==Article purpose==<br />
The purpose of this article is to:<br />
* briefly introduce the SPI peripheral and its main features<br />
* indicate the level of security supported by this hardware block<br />
* explain how each instance can be allocated to the three runtime contexts and linked to the corresponding software components<br />
* explain, when necessary, how to configure the SPI peripheral and for some of them the I2S features.<br />
<br />
==Peripheral overview==<br />
The SPI peripheral can be used to communicate with an external devices using the SPI (Serial Peripheral Interface).<br> <br />
A subset of the SPI instances supports the I2S audio protocol. These '''SPI/I2S''' peripherals can alternatively be used in '''audio''' applications, when they are configured as an I2S interface. Refer to [[#Peripheral assignment|peripheral assignment chapter]] to check I2S feature support for each SPI instance.<br />
<br />
===Features===<br />
==== SPI main features ====<br />
* Full-duplex, half-duplex and simplex synchronous modes.<br />
* Slave and master modes.<br />
<br />
==== I2S main features ====<br />
Only available for SPI supporting I2S mode.<br />
* Full-duplex or simplex modes.<br />
* Slave and master modes.<br />
* Four audio protocols supported.<br />
<br />
==== Specific features ==== <br />
Some of the SPI peripheral characteristics depend on I2S support, as summarized in following table:<br />
{| class="wikitable"<br />
! SPI modes/features<br />
! I2S supported<br />
! I2S not supported<br />
|-<br />
| Rx & TxFIFO size (N) [x 8-bit]<br />
| 16<br />
| 8<br />
|-<br />
| Maximum configurable data size [bits]<br />
| 32<br />
| 16<br />
|}<br />
<br />
Refer to [[STM32MP15 resources#Reference manuals|STM32MP15 reference manuals]] for the complete list of features, and to the software components, introduced below, to see which features are implemented.<br><br />
<br />
===Security support===<br />
SPI6 is a '''secure''' peripheral (under ETZPC control).<br><br />
The other SPI instances are '''non-secure''' peripherals.<br />
<br />
==Peripheral usage and associated software==<br />
===Boot time===<br />
The SPI is not used at boot time.<br />
<br />
===Runtime===<br />
====Overview====<br />
The SPI6 can be allocated to: <br />
* the Arm<sup>&reg;</sup> Cortex<sup>&reg;</sup>-A7 secure core to be controlled in OP-TEE by the SPI OP-TEE driver<br />
<br />
All the SPI instances can be allocated to:<br />
* the Arm<sup>&reg;</sup> Cortex<sup>&reg;</sup>-A7 non-secure core to be controlled in Linux<sup>&reg;</sup> by:<br />
:* the SPI framework for SPI configured in SPI mode <br />
:* the ALSA framework for SPI configured in I2S mode<br />
or<br />
* the Cortex-M4 to be controlled in STM32Cube MPU Package by [[STM32CubeMP1 architecture|STM32Cube SPI driver]]<br />

<br />
Chapter [[#Peripheral assignment|Peripheral assignment]] describes which peripheral instance can be assigned to which context.<br />

|-<br />
|}<br />
<br />
====Peripheral configuration====<br />
The configuration is applied by the firmware running in the context to which the peripheral is assigned. The configuration by itself can be done via [[STM32CubeMX]] tool for all internal peripheral, then it can manually be completed (especially for external peripherals) according to the information given in the corresponding software framework article.<br />
<br />
When the Arm<sup>&reg;</sup> Cortex<sup>&reg;</sup>-A7 core operates in non-secure access mode, the SPI is controlled by the Linux kernel framework.<br />
<br />
* SPI mode:<br />
Refer to [[SPI_overview|SPI framework]] to check how to drive SPI through Linux kernel.<br />
<br />
* I2S mode:<br />
Refer to [[I2S Linux driver]] to drive the SPI through Linux kernel [[ALSA_overview|ALSA framework]]. Refer to [[Soundcard configuration]] to configure it through the Linux kernel device tree<ref>[[Device tree]]</ref>.<br />
