STM32CubeMX errata 6.14.x

1. Main fixed issues for 6.14.0

ID Summary
196934 For the STM32CubeMX projects based on STM32H745IIT3 MCU the action of disabling The JPEG peripheral configured with MDMA fails if multiple MDMA requests are queued.

The correction for this matter was provided with STM32CubeMX 6.14.0.

197123 The STM32CubeMX is overwriting the generated '.cproject' file by renaming it'.cproject.bak' when switching from one toolchain to another one in the regeneration stage

This issue disappeared with STM32CubeMX 6.14.0

197842 A compatibility issue prevents STM32CubeMX 6.13.0 from opening the IOC files generated by earlier versions (up to and including 6.13.0) when configured for STM32H5 or STM32H7Sx/STM32H7Rx microcontrollers with both Ethernet and the memory management tool active.

The STM32CubeMX 6.14.0 integrates the solution for this issue

198064 Generating a project from either the BLE_Beacon_AoA_Tag or BLE_Beacon_Scanner_AoA_Locator example in STM32CubeMX 6.13.0 and subsequently building it in STM32CubeIDE results in a build failure due to missing osal.h and compiler.h header files.

The STM32CubeMX 6.14.0 integrates the solution for this issue

198146 The Linked List utility is unavailable for STM32H533 microcontrollers within the Utilities category of STM32CubeMX 6.13.0.

The Linked List utility is available for STM32H533 microcontrollers in STM32CubeMX 6.14.0.

199154 An issue with the initialization of the interrupt handler for DMA1 channels 4-7 and DMAMUX overrun events on the STM32U031xx microcontroller. The generated code in stm32u031xx.h references the interrupt with a definition that does not align with the corresponding entry in the IRQn_Type enumeration in the firmware.

The STM32CubeMX 6.14.0 contains the fix for the issue.

2. Known limitations

  • For the STM32 products supporting the ThreadX feature natively ,the build of the projects that enable ThreadX in "Low Power Support"mode with Makefile or CMake toolchains results in warnings.
  • The compare Projects tool cannot compare projects for which the DMA (Direct Memory Access) feature is enabled.
  • From Ubuntu version 23.10 and subsequent, when using CAD > tools then selecting 'MCU commercial part number' to configure CAD > MCU selector, the CAD viewer is not functional.
  • In the case of file access issue during a compilation with some examples on partner IDEs (for instance with the “cannot open-source input file” error message), consider to move either the full package manually, or just the example. For the example, use the Example Selector from STM32CubeMX, closer to the root of the disk (long path issue).
  • If “CAD resources” feature is not fully functional when using “Use System Proxy parameters”, try to use the “Manual Configuration of Proxy Server” or “No proxy” instead. (Menu : [Updater Settings…]>[Connection Parameters])
  • When unzipping a package on a macOS® system, use an official macOS® application such as the default graphical archive application, or the ditto tool in the command line:
    $ditto -x -k setupArchive.zip
    If a Linux®-like application is used (such as unzip), the expanded files lose the signature and are not recognized as signed.
  • For users of Keil® MDK, particularly those utilizing STM32CubeMX generated projects, a critical update regarding default toolchains is in effect. Starting with Keil® MDK version 5.37, Arm Compiler 6 (AC6) has become the default, superseding the deprecated Arm Compiler 5 (AC5). This change introduces a compatibility concern for specific STM32 products. Notably, STM32Fx, STM32L (0x, 1x, 4x), STM32H7 (2x, 3x, 4x, 5x, Ax, Bx), STM32Gx, STM32WB (1x, 3x, 5x), and STM32MP15x series,Users may encounter compilation errors when using the AC6 compiler with the previously listed products. An error message appears to indicate that the required Arm Compiler is unavailable.
    • Workaround: By following the steps below, you can continue using Arm Compiler 5 and avoid potential issues with STM32 projects of the products listed previously:
  1. Download Arm Compiler 5 manually from https://developer.arm.com/documentation/ka005198/latest/.
  2. Follow the step-by-step instructions available in this guide [1] to add Arm Compiler 5 to Keil® MDK 5.37 or newer.
  3. Once installed, select AC5 as the Arm Compiler of your project settings.

2.1. When selecting microcontrollers in the STM32G0 series

  • Regarding the cohabitation between USB and USB Power Delivery, the VID and PID of USB Power Delivery and USB are not automatically aligned. VID/PID values must be aligned manually.
  • When both the USB Power Delivery and FreeRTOS™ CMSIS_V1 middleware are enabled at the same time, the FreeRTOS™ eTaskGetState parameter must be enabled in the include parameters tab.

2.2. When selecting microcontrollers in the STM32G4 series

  • When attempting to create a new STM32G411 project using STM32CubeMX with the firmware "STM32Cube_FW_G4_V1.6.0", the project creation fails. Instead of generating a correctly structured project, the process terminates unexpectedly.

2.3. When selecting microcontrollers in the STM32H5 series

  • When migrating projects with OEM-iROT boot path from STM32CubeMX V6.8.x to STM32CubeMX V6.10.x or later releases, the user might need to reconfigure ROT_Provisioning.
  • The makefile generation no longer works as soon as the project structure is changed from "Secure Project only" or "Non Secure Project only" to "Secure Project and Non Secure Project enabled (dual project)".
  • In Microsoft® Azure® NetX Duo, some configuration flags, which are not used in the STM32Cube firmware package examples, might be nonfunctional when combined.

2.4. When selecting microcontrollers in the STM32H7 series

  • A compilation issue appears in the build of STM32H7RS examples that activate the TRACER_EMB utility and use STM32CubeIDE toolchain due to a limitation in the size of TRACER_EMB_STRUCTURE_MEMORY_LOCATION buffer.
    • The solution involves modifying the linker file to allocate a larger non-cacheable Buffer memory region.

tracer.png

  • During the migration from an older STM32H7 project (created with STM32CubeMX version coming earlier than V6.13.0) to the STM32CubeMX V6.13.0, The following files aren't automatically updated:

system_stm32h7xx.c and startup_stm32h7nnxx.s which are needed for the correct initialization of the system power supply.

  • This limitation might appear: An early RAM access prior to the configuration of the system power supply which is not allowed.
    • For new projects created by STM32CubeMX v6.13.0 and later, those files are correctly updated.
    • The system power supply configuration is also kept in SystemClock_Config() to avoid runtime issue with existing projects.
    • The workaround :To successfully migrate the project:The user should Copy the new files from the firmware side and ensure that they are correctly included in the project. In addition he should verify the compiler compatibility: he should use the appropriate startup_stm32h7nnxx.s file for the chosen compiler.
  • For the STM32H7Sx microcontrollers in the STM32H7 series, when using the NUCLEO-H7S3L8 board, the boot path is not supported. It is only supported for STM32H7S78-DK board or custom boards with the same flash and same pin mapping.
  • For the STM32H7Rx microcontrollers in the STM32H7 series, the boot path is not supported and Debug authentication is disabled.
  • MDMA and HSEM are not supported in LL. Only HAL is supported.
  • When activating any mode under SPDIFRX:
    • The alternate function configuration code is not generated in the HAL_SPDIFRX_MspInit function in the stm32h7xx_hal_msp.c file.
    • Add the workaround code in the user section after “GPIO_InitStruct.Speed =GPIO_SPEED_FREQ_LOW;” as described in Table 2 depending on the channel and selected pin.
Table 2. Workaround for alternate function configuration code
Channel Selected pin Workaround code
IN0 PD7 /* USER CODE BEGIN alternate function configuration */
GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF;
/* USER CODE END alternate function configuration */
PG11 /* USER CODE BEGIN alternate function configuration */
GPIO_InitStruct.Alternate = GPIO_AF8_SPDIF;
/* USER CODE END alternate function configuration */
IN1 PD8 /* USER CODE BEGIN alternate function configuration */
GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF;
/* USER CODE END alternate function configuration */
PG12 /* USER CODE BEGIN alternate function configuration */
GPIO_InitStruct.Alternate = GPIO_AF8_SPDIF;
/* USER CODE END alternate function configuration */
IN2 PC4 /* USER CODE BEGIN alternate function configuration */
GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF;
/* USER CODE END alternate function configuration */
PG8 /* USER CODE BEGIN alternate function configuration */
GPIO_InitStruct.Alternate = GPIO_AF8_SPDIF;
/* USER CODE END alternate function configuration */
IN3 PC5 /* USER CODE BEGIN alternate function configuration */
GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF;
/* USER CODE END alternate function configuration */
PG9 /* USER CODE BEGIN alternate function configuration */
GPIO_InitStruct.Alternate = GPIO_AF8_SPDIF;
/* USER CODE END alternate function configuration */

2.5. When selecting dual-core microcontrollers in the STM32H7 series

  • Only Boot0 is supported: both cores boot at once.
  • Import from and to dual-core STM32H7 is not supported.
  • For memory-to-memory DMA or BDMA or MDMA configuration, the initialization code is generated for both cores.
  • OpenAMP issue when compiling under EWARM and MDK-ARM when OpenAMP is activated under STM32CubeMX:
    • To avoid link errors in OpenAMP when compiling in EWARM IDE, add the next four lines of code in the linker files (.icf):
/* Create region for OPENAMP */
define symbol __OPENAMP_region_start__ = 0x38000400;
define symbol __OPENAMP_region_size__ = 0xFC00;
export symbol __OPENAMP_region_start__;
export symbol __OPENAMP_region_size__;
  • To avoid link errors in OpenAMP when compiling in MDK-ARM IDE, add the next four lines of code in the linker files (.sct):
; ***** Create region for OPENAMP *****
.resource_table +0 ALIGN 4 { ; resource table
*(.resource_table)
}
; Shared Memory area used by OpenAMP
__OpenAMP_SHMEM__ 0x38000400 EMPTY 0xFC00 {}
  • OpenAMP under STM32CubeIDE needs linker file update:
    • The following lines must be added under the .ld file:
/* Specify the memory areas */
MEMORY
{
...
m_ipc_shm (RW) : ORIGIN = 0x38000400, LENGTH = 63K
}
/* Symbols needed for OpenAMP to enable rpmsg */
__OPENAMP_region_start__=ORIGIN(m_ipc_shm);
__OPENAMP_region_end__=ORIGIN(m_ipc_shm)+LENGTH(m_ipc_shm);

2.6. When selecting microcontrollers in the STM32L5 series

  • Arm® TrustZone® support:
    • Fixed default SAU is configured in the application partition_stm32l552xx.h and partition_stm32l562xx.h files.
    • Import does not work for TrustZone® projects (TZEN=1).
  • To facilitate the peripheral privilege configuration, from STM32CubeMX V6.2.0, the GTZC peripheral is split into two domains: secure and nonsecure. The side effect is that, in the case of project migration from a release version before V6.2.0, if GTZC is configured in both the secure and nonsecure domains with previously configured privilege peripherals on a nonsecure peripheral, this configuration is lost during the migration. The GTZC_NS privileges must be configured again.
  • Regarding the cohabitation between USB and USB Power Delivery, the VID and PID of USB Power Delivery and USB are not automatically aligned. VID/PID values must be aligned manually.

2.7. When selecting microcontrollers in the STM32N6 series

  • The contexts alignment for interdependent middleware is not automatically managed in STM32CubeMX. To avoid compilation errors,if the user activates a middleware that depends on another middleware/IP within a specific context, he must ensure that the dependent middleware/IP is also set with the same context.
Info white.png Information
Dependencies among Middleware might be a:
  • Total dependency (middleware/ip):The dependent ip or middleware can't be configured unless the first middleware is active for example the dependency of NetXduo on ThreadX or of the USBX on USB1_OTG_HS and/or USB2_OTG_HS.
  • Partial dependency (modes):A given mode activation needs the activation of the related middlware for example the modes of FileX depend on LevelX activation.
  • Code generation dependency:The generated code is going to be modified once a middleware is active for example USBX code generation changed when enabling ThreadX.
  • To avoid linking issues with Keil® MDK-ARM when a USBX Core System is enabled, the following modes should be enabled :
    • "UX Host HS1" or "UX Device HS1" if USB1_OTG_HS IP is used.
    • "UX Host HS2" or "UX Device HS2" if USB2_OTG_HS IP is used.
  • Warning messages appear after building a project that configure the ThreadX with 'Low Power Support' mode, regardless of the toolchain.
  • During the external memory flashing, two XML parsing errors occur in the following files:
  1. EXTMEM-LOADER.board due to a leading blank line, the user can fix the error by removing this blank line
  2. EXTMEM-LOADER.flash due to a faulty XML element inside it, the user can resolve the error by deleting the below content from the file
<pass>
<range>CODE 0x08000000 0x0800FFFF</range>
<loader_offset> 0x20000000</loader_offset>
<loader>$TOOLKIT_DIR$\config\flashloader\ST\FlashSTM32H7R-Sxx8.flash</loader>
</pass>
  • In the full LL mode, the function that activates the VddIOx power domain LL_PWR_EnableVddIOx() is missing from STM32CubeMX generated code. Consequently, there's no signal in some pins. (Note that for LL_PWR_EnableVddIOx() and VddIOx the x could be 2,3,4,5 depends on the activated power domain)
    • To fix the issue the user should add manually the LL_PWR_EnableVddIOx() in the main() after calling SystemClock_Config() when working in full LL mode.
  • Projects utilizing the DCMIPP peripheral may encounter errors due to the generated code lacking essential GPIO initialization/deinitialization and clock activation instructions.
    • The user needs to check the GPIO Settings panel of the DCMIPP configuration, and for each IO, he should add manually its configuration and the related clock instruction.
    • For example, if DCMIPP_D0 is in PD7, the following code should be added to HAL_DCMIPP_MspInit():
 __HAL_RCC_GPIOD_CLK_ENABLE();
GPIO_InitStruct.Pin = GPIO_PIN_7;

GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;

GPIO_InitStruct.Pull = GPIO_NOPULL;

GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;

GPIO_InitStruct.Alternate = GPIO_AF9_DCMIPP;//===Note that if "PE6", "PN9" and "PF10" pins are used the instruction become GPIO_InitStruct.Alternate = GPIO_AF10_DCMIPP;===

HAL_GPIO_Init(GPIOD, &GPIO_InitStruct);
  • When activating the DCMIPP and the CSI features the clock is not fully configured in the generated code, the user needs to add manually the following instructions in the stm32n6xx_hal_msp.c
/* USER CODE BEGIN DCMIPP_MspInit 0 */
PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_CSI;
PeriphClkInitStruct.ICSelection[RCC_IC18].ClockSelection = RCC_ICCLKSOURCE_PLL1;
PeriphClkInitStruct.ICSelection[RCC_IC18].ClockDivider = 60;
if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK)
{   
   Error_Handler(); 
}
/* Enable CSI clock */
__HAL_RCC_CSI_CLK_ENABLE();
__HAL_RCC_CSI_FORCE_RESET();
__HAL_RCC_CSI_RELEASE_RESET();

HAL_NVIC_SetPriority(CSI_IRQn, 0x07, 0);
HAL_NVIC_EnableIRQ(CSI_IRQn); 

void CSI_IRQHandler(void)
{ 
  HAL_DCMIPP_CSI_IRQHandler(&hdcmipp);
}
/* USER CODE END DCMIPP_MspInit 0 */

2.8. When selecting microcontrollers in the STM32U5 series

  • Regarding the cohabitation between Azure® RTOS USBX and USB Power Delivery, the VID and PID of USB Power Delivery and USBX are not automatically aligned. VID/PID values must be aligned manually.
  • To avoid linking issues with Keil® MDK-ARM when a USBX Core System is enabled, "Device CoreStack FS" or "Host CoreStack FS" must be enabled according to the USB_OTG_FS selected mode.
  • To avoid compilation issues when one DMA channel request is activated for one TIMx peripheral, replace htim_xx by htim_base. For example, replace:
    __HAL_LINKDMA(htim_oc, hdma[TIM_DMA_ID_CC1], handle_GPDMA1_Channel11);
    by
    __HAL_LINKDMA(htim_base, hdma[TIM_DMA_ID_CC1], handle_GPDMA1_Channel11);
  • In Microsoft® Azure® NetX Duo, some configuration flags, which are not used in the STM32Cube firmware package examples, might be nonfunctional when combined.

2.9. When selecting microcontrollers in the STM32WB series

  • The value of the CFG_BLE_MAX_CONN_EVENT_LENGTH parameter in the file app_conf.h is wrongly formatted: uint16_t is used instead of uint32_t. This impacts the Data Throughput of the application since the max value is 0xFFFF, while it should be 0xFFFF FFFF. The defined value must be changed manually in the generated code.

2.9.1. When selecting microcontrollers in the STM32WB0 product lines

  • The following expansions packages for STM32Cube are not supported by microcontrollers from the STM32WB0 product lines:
    • X-CUBE-NFC10
    • X-CUBE-NFC9
    • X-CUBE-NFC4
    • X-CUBE-NFC10
    • X-CUBE-NFC6
    • X-CUBE-WB05N
    • X-CUBE-IPS
    • X-CUBE-TCPP
    • X-CUBE-SAFEA1
    • X-CUBE-GNSS1
    • X-CUBE-SUBG2
    • X-CUBE-EEPRMA1
    • X-CUBE-TOF1
    • X-CUBE-ALS
    • X-CUBE-BLEMGR
    • X-CUBE-ISPU
    • X-CUBE-BLE1
    • X-CUBE-BLE2
    • X-CUBE-MEMS1
    • X-CUBE-SFXS2LP1

2.10. When selecting microcontrollers in the STM32WBA series

  • When the selected middleware is STM32WPAN for Bluetooth® Low Energy with the parameter CFG_BLE_NUM_LINK set above 8, use the Bluetooth® Low Energy link layer library LinkLayer_BLE_Basic_20_links_lib.a with the header file from the path \link_layer\ll_cmd_lib\config\ble_basic_20_links.

2.11. When selecting microcontrollers in the STM32WL series

  • If LoRaWAN®, SubGHZ_Phy or SigfoxTM middleware is used with the option Generate peripheral initialization as a pair of '.c/.h' files per peripheral disabled, it is advised to untick the visibility of the SUBGHZ and IPCC peripherals in [Project Manager]>[Advanced Settings] Generated Function Calls panel to avoid an issue when compiling.
  • Import from and to dual-core is not working for the STM32WL series.
  • For dual-core products, IPCC LL + RF middleware (LoRaWAN®, SigfoxTM, and SubGHZ_Phy) are not supported.
  • If a Sigfox project is generated with MDK-ARM, the following option must be set in the project Options C/C++(AC6) panel: Misc Controls: -fshort-enums
  • The SUBGHZ peripheral is forced on the Cortex®-M0+.
  • In the case of a project migration from a release version before V6.2.0, to facilitate the GTZC configuration, some previously default configuration ("enabled"/"disabled") has been moved to "default" configuration. This new state provides the default configuration of the MCU without any code generation. Users specifically needing this code generation must modify this state.
  • When compiling under IAR Embedded Workbench®, in case of dual-core products, the user must activate the share mode in both CM4 and CM0PLUS ST-LINK project options.
  • The "Time base: System tick timer" value selected in the NVIC configuration panel is not used for the code generation. This value must be updated by the end user in the generated code.
  • KMS and STM32Cube Azure® RTOS ThreadX cannot be enabled in the same core.

2.11.1. When selecting microcontrollers in the STM32WL33 product lines

  • The following expansions packages for STM32Cube are not supported by microcontrollers from the STM32WL33 product lines:
    • X-CUBE-NFC10
    • X-CUBE-NFC9
    • X-CUBE-NFC4
    • X-CUBE-NFC10
    • X-CUBE-NFC6
    • X-CUBE-WB05N
    • X-CUBE-IPS
    • X-CUBE-TCPP
    • X-CUBE-SAFEA1
    • X-CUBE-GNSS1
    • X-CUBE-SUBG2
    • X-CUBE-EEPRMA1
    • X-CUBE-TOF1
    • X-CUBE-ALS
    • X-CUBE-BLEMGR
    • X-CUBE-ISPU
    • X-CUBE-BLE1
    • X-CUBE-BLE2
    • X-CUBE-MEMS1
    • X-CUBE-SFXS2LP1

2.12. When selecting microprocessors in the STM32MP1 series

  • DMA nodes are generated in the device tree, but the DMA properties in the IP clients nodes are not generated.
  • Import from and to MPU projects does not work properly.
  • Dual-core project structure compatibility break : the action to import (migrate or continue) projects created with versions earlier than STM32CubeMX V5.3.0 is supported but requires the manual copy of USER SECTIONS for the device tree and Cortex®-M4 firmware from the former folder structure (DeviceTree/Inc/Src) to the new one (CA7/DeviceTree - CM4/Src - CM4/Inc).
  • Additional software is not supported.
  • RCC generation in Production mode is not supported on the coprocessor side. Only the Engineering mode is supported.
    By default, the STM32CubeMX-generated code is compliant with the Engineering mode. Therefore, the call of the following clock functions must be removed in the Production mode since these clocks are then managed by Linux®: SystemClock_Config(), PeriphCommonClock_Config(), and HAL_RCCEx_PeriphCLKConfig():
    • The system parts (SystemClock_Config() and PeriphCommonClock_Config()) can be removed in STM32CubeMX by selecting [Not Generate function call] for RCC in the Project Manager, then Advanced Settings tabs.
    • HAL_RCCEx_PeriphCLKConfig() must be removed manually from file stm32mp1xx_hal_msp.c (STM32CubeMX-generated code).
    • To make the user code compatible with both the engineering and production modes, the above RCC functions can be put under dynamic condition
      if(IS_ENGINEERING_BOOT_MODE()).
  • On macOS®, installation issues may result from the fact that the install is not signed. Use the following procedure:
    • Download STM32CubeMX on a Window® OS personal computer.
    • Copy the downloaded install into the macOS® personal computer.
    • Launch the install.
  • OpenAMP warning when compiling under MDK-ARM if OpenAMP is not activated under STM32CubeMX:
    • Remove the next four lines of code from the linker files (.sct) to avoid warning “No section matches pattern *(.resource_table)”:
; ***** Comment these 4 lines if OPENAMP is not used *****
.resource_table +0 ALIGN 4 { ; resource table
*(.resource_table)
}
; Shared Memory area used by OpenAMP
__OpenAMP_SHMEM__ 0x10040000 EMPTY 0x8000 {}
  • Device tree generation: the "pwr" user section name is changed to "pwr_regulators".
    • Existing code in the "pwr" user section must be backed up and reported manually into the new "pwr_regulators" user section after code generation.
  • About the HRTIM peripheral: for the "Set Source Selection" & "Reset Source Selection" parameters, the "No source is selected" must be manually set for any unused source before decreasing the number of sources.
  • When using the STM32CubeMP13 bare-metal firmware, the secure mode of the peripheral RTC is not available for the STM32MP13xx microprocessors. It is only available when the STM32CubeMP1 MCU package is used.
  • When using the STM32CubeMP13 bare-metal firmware and activating Azure® RTOS ThreadX, the STM32CubeIDE linker file must contain the following section to avoid compilation issues:
.stack:
{
 _stack_bottom = ABSOLUTE(.) ;
 /* Allocate room for stack. This must be large enough for the
 IRQ, FIQ, and SYS stack if nested interrupts are
 enabled.*/
 . = ALIGN(8) ;
 . += 32768 ;
 _sp = . - 16 ;
 _stack_top = ABSOLUTE(.) ;
 } >RAM
 _end = .;

2.13. When using the Memory Management Tool

  • Linker file issues may result from configuring MMT after the initial code generation (more precisely activating the MMT in the second code generation).
  • When using the Memory Management Tool in a project based on CMake or Makefile build generators,The following configurations are not supported:
    • The TrustZone activation.
    • The Use of the STM32H7Rx/7Sx microcontrollers from the STM32H7 serie.
  • For the projects based on STM32WB series and using the MMT,the generated linker file in not taking into account the activation of the option "Boot Info".
  • When settingthe mode of the Extmem Manager in the boot runtime context , the Memory Management Tool generates only an 'Execute' memory region and omits the 'LOAD_REGION' one. The 'LOAD_REGION' is displayed as reserved in the UI. This limitation applies to all toolchains and IDEs.
  • The linker script is not automatically updated to incorporate the 'isrvercor' configuration.

2.14. When using the Example Selector

  • When generating STM32CubeMX (version 6.13.0) projects for RF applications of the STM32WB0x and STM32WBA5x series, with the STM32CubeIDE selected as a tool chain, users may encounter issues with the generated project structure. More precisely essential header files might be missing, resulting in compilation errors.
    • Workaround: To address this issue, it is recommended to regenerate the project within STM32CubeMX.
  • When starting an example from the Example Selector and regenerating the code, some files can be duplicated. It can lead to potential compilation issues. In this case, remove the duplicated files.

2.15. When using additional software packs

  • If a software component refers to a specific peripheral, this peripheral must be initialized with HAL APIs (not with LL APIs).
  • When using dual-core devices, if a software component refers to a specific peripheral, this peripheral must be assigned only to the same core as the software component.
  • When a pack is disabled, the generated files are not removed from the project. Workaround: remove these files manually.
  • Functionalities that are not supported:
    • maxInstances, isDefaultVariant, generator attributes of the component element
    • Dtz, Ddsp, Dsecure attributes of the condition element
    • repository element
    • tag and url attributes of a release element
    • dominate element
    • public attributes for the file element
    • preIncludeLocal and preIncludeGlobal file category attributes
    • Pre_Include_Local_h element
    • Pre_Include_Global_h element
    • Pack components where attribute values come with a "." character
  • Compilation issues when using both X-CUBE-AZRTOS-H7 v1.1.0 and OpenAMP middleware in the same project with minimum version MDK-ARM v5.32:
    X-CUBE-AZRTOS-H7 v1.1.0 requires Arm C compiler version 6 while OpenAMP is not compatible with this version (only Arm C compiler version 5 is supported). The workaround consists in using X-CUBE-AZRTOS-H7 v1.0.0 instead. This one is compatible with Arm C compiler version 5.
  • In the case of an error message when downloading SEGGER I-CUBE-embOS:
    • Download SEGGER.I-CUBE-embOS manually from the SEGGER download site at https://www.segger.com/downloads/embos.
    • Open the STM32CubeMX Embedded Software Packages Manager.
    • Use the option Load from Local and select the pack.

2.16. STM32CubeIDE toolchain

  • It is functional only with a Java 8 64-bit virtual machine with versions earlier than STM32CubeMX V5.6.1.

2.17. DDR test suite

  • STM32CubeProgrammer (STM32CubeProg) is not supported from v2.10.0 onwards.

2.18. User manual

  • Some chapters in the user manual STM32CubeMX for STM32 configuration and initialization C code generation (UM1718) are not fully up to date.

2.19. Symbolic links on Ubuntu

  • When using Ubuntu 20.04 if you use a symbolic link to refer to the "Firmware Relative Path" in the STM32CubMX Project Manager tab, it will be translated to the absolute path before saving down.

3. Recommendations

3.1. Command line authentication required

Since introduction of authentication at the command level, we recommend our costumers to review their scripts. They should make sure they are authenticating before trying to download a package or before trying to generate code on the command line. Failure to do so will result on errors displayed on the command line.

3.2. DDR binaries for the STM32MP1 boards

The DDR binaries needed to connect to the STM32MP1 boards are available from the GitHub website at https://github.com/ with the keyword STMicroelectronics/STM32DDRFWUTIL.

3.3. List pinout-compatible microcontrollers

The loading of microcontrollers can take a long time if all series and all packages are selected. If the loading takes too long, stop it, refine the microcontroller filters on a dedicated series or package, and restart the loading.

3.4. How to improve the wake-up from Stop sequences without relying on the global SystemClock_Config()

The SystemClock_Config provided in the HAL examples is intended to be used to configure the system clock at startup. It is not recommended to use it to restore the clock settings after a Stop mode.
To keep the wake-up as quick as possible, it is highly recommended to restore only what has been changed by the hardware to enter the Low-power mode. This is typically the case for the oscillators and system clock sources. The RCC configuration registers are unchanged, and there is no need to restore them.
Typically, after a Stop mode, it is recommended to call a separate SystemClockConfig_STOP after the wake-up that enables the LSE and PLL, and selects PLL as system clock source (LSE and PLL are disabled in Stop mode). Find below an example of SystemClockConfig_STOP (provided in the HID_Standalone_LPM application):

static void SystemClockConfig_STOP(void)
{
#if defined (USB_USE_LSE_MSI_CLOCK)
:/* Configures system clock after wake-up from STOP: enable LSE,
:PLL and select PLL as system clock source (LSE and PLL are disabled in Stop mode) */
:__HAL_RCC_LSE_CONFIG(RCC_LSE_ON);
:/* Wait till HSE is ready */
:while(__HAL_RCC_GET_FLAG(RCC_FLAG_LSERDY) == RESET)
:{}
:/* Enable the main PLL. */
:__HAL_RCC_PLL_ENABLE();
:/* Wait till PLL is ready */
:while(__HAL_RCC_GET_FLAG(RCC_FLAG_PLLRDY) == RESET)
:{}
:/* Select PLL as SYSCLK */
:MODIFY_REG(RCC->CFGR, RCC_CFGR_SW, RCC_SYSCLKSOURCE_PLLCLK);
:/* Wait till system clock switch to PLL */
:while (__HAL_RCC_GET_SYSCLK_SOURCE() != RCC_CFGR_SWS_PLL)
:{}
#elif defined (USB_USE_HSE_CLOCK)
:/* Configures system clock after wake-up from STOP: enable HSE,
:PLL and select PLL as system clock source (HSE and PLL are disabled in Stop mode) */
:__HAL_RCC_HSE_CONFIG(RCC_HSE_ON);
:/* Wait till HSE is ready */
:while(__HAL_RCC_GET_FLAG(RCC_FLAG_HSERDY) == RESET)
:{}
:/* Enable the main PLL. */
:__HAL_RCC_PLL_ENABLE();
:/* Wait till PLL is ready */
:while(__HAL_RCC_GET_FLAG(RCC_FLAG_PLLRDY) == RESET)
:{}
:/* Select PLL as SYSCLK */
:MODIFY_REG(RCC->CFGR, RCC_CFGR_SW, RCC_SYSCLKSOURCE_PLLCLK);
:/* Wait till system clock switch to PLL */
:while (__HAL_RCC_GET_SYSCLK_SOURCE() != RCC_CFGR_SWS_PLL)
:{}
#endif /* USB_USE_LSE_MSI_CLOCK */
