OpenSTLinux distribution does not provide the flash memory layout (flashlayout) files required to use a UART as a serial boot device.

Refer to Using_STM32Programmer_over_UART article to see how to modify a flashlayout file to use a UART as serial boot device.

You can use this modified flashlayout as described in STM32CubeProgrammer#How to flash with STM32CubeProgrammer article.

For example, the provided FlashLayout_sdcard_stm32mp157c-dk2-optee.tsv file can be used on USB with the command: 

 
  STM32_Programmer_CLI -c port=usb1 -w FlashLayout_sdcard_stm32mp157c-dk2-optee.tsv

By replacing tf-a-stm32mp157f-dk2-usb.stm32 to tf-a-stm32mp157f-dk2-uart.stm32 in this tsv file, the resulting file FlashLayout_sdcard_stm32mp157c-dk2-optee_uart.tsv can be used on UART port /dev/ttyACM1 with the command: 

 
  STM32_Programmer_CLI -c port=/dev/ttyACM1 -w FlashLayout_sdcard_stm32mp157c-dk2-optee_uart.tsv

OpenSTLinux distribution does not provide the flash memory layout (flashlayout) files required  to use a UART as a serial boot device.

Refer to [[STM32CubeProgrammer_flashlayout#Using_STM32Programmer_over_UART|Using_STM32Programmer_over_UART]] article to see how to modify a flashlayout file to use a UART as serial boot device.

You can use this modified flashlayout as described in [[STM32CubeProgrammer#How to flash with STM32CubeProgrammer article]].

For example, the provided '''FlashLayout_sdcard_stm32mp157c-dk2-optee.tsv''' file can be used on USB with the command:

  {{PC$}}  STM32_Programmer_CLI -c port={{Highlight|usb1}} -w {{HighlightParam|FlashLayout_sdcard_stm32mp157c-dk2-optee.tsv}}

By replacing '''tf-a-stm32mp157f-dk2-{{Highlight|usb}}.stm32''' to '''tf-a-stm32mp157f-dk2-{{Highlight|uart}}.stm32''' in this tsv file, the resulting file {{HighlightParam|FlashLayout_sdcard_stm32mp157c-dk2-optee}}{{Highlight|_uart}}{{HighlightParam|.tsv}} can be used on UART port {{Highlight|/dev/ttyACM1}} with the command:

  {{PC$}}  STM32_Programmer_CLI -c port={{Highlight|/dev/ttyACM1}} -w {{HighlightParam|FlashLayout_sdcard_stm32mp157c-dk2-optee}}{{Highlight|_uart}}{{HighlightParam|.tsv}}
