How to rebuild TF-A (Trusted Firmware-A) for STM32MP157C-DK2 ?

I am using the STM32MP157C-DK2

For testing purpose I need to build and replace the BSP and in particular the bootloader.

The documentation is a bit messy and I'm not able to find the information I need.

I need to rebuild and replace TF-A and u-boot.

I read so far:

https://wiki.st.com/stm32mpu/wiki/TF-A_overview

https://wiki.st.com/stm32mpu/wiki/STM32MP1_Starter_Package_-_images

https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout

Where I can find all the sources and documentation explaining how to rebuild TF-A (Trusted Firmware-A)?

Thank you.

Hi @Community member​ ,

thank you for answering.

I read in chapter 5.4 Installing the TF-A

tf-a-stm32mp-2.0-r0 TF-A installation directory
├── [*].patch ST patches to apply during the TF-A preparation (see next chapter)
├── arm-trusted-firmware-2.0 TF-A source code directory
├── Makefile.sdk Makefile for the TF-A compilation
├── README.HOW_TO.txt Helper file for TF-A management: reference for TF-A build
├── series List of all ST patches to apply
└── v2.0.tar.gz Tarball file of the TF-A source code

Where is next chapter ?

Hi @Community member​ 

thanks to your clarification I built

make -f $PWD/../Makefile.sdk all

I see the *.stm32 files, but I don't have the *.tsv needed to run STM32CubeProgrammer.

What's missing?

Hi @koan​ 

This is normal, developper package does not manage .tsv generation.

Please see section 6 in same readme to update the TF-A partition without STM32CubeProgrammer/.tsv

Else you can still use STM32CubeProgrammer by updating the .tsv provided in Starter Package with your custom TF-A binary.

Hope it help,

Olivier
