tf-a and u-boot custom compile fails

[ASkri.1]

Hi, Everybody!

Referring to this issue:

https://community.st.com/s/question/0D53W00000oVNtqSAG/qaudspi-spinand-flash-device-tree-for-tfa-and-uboot

PatrickF suggested to manually configure U-BOOT for my board. I have downloaded tf-a sources patched it, of course installed and configured SDK and trying to do all according to it's README.HOW_TO.txt file.

As I have my specific DT I need to specify it in makefile parameters:

README.HOW_TO.txt has this example:

make -f $PWD/../Makefile.sdk TFA_DEVICETREE=stm32mp157c-ev1 TF_A_CONFIG=trusted ELF_DEBUG_ENABLE='1' all

But in fact TFA_DEVICETREE var-name should be TF_A_DEVICETREE. Is this correct?

Then, file format. We have .stm32, also .fip file format avaialble

I can compile both .stm32 tf-a and u-boot, but u-boot fail to start with following error:

Then I'm trying to compile tf-a with fip option, but it fails with following error:

Why optee? I don;t need optee.

Can anybody help me with correct sequence compiling tf-a and u-boot starting from source download and finishing with success kernel load...

Thank you in advance

Looking forward for your reply

Hi,

This wiki page might help you: https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package.

Please note that with a defined Ecosystem SDK (here v3), you should also be careful with the tools versions (e.g. CubePro, CubeMX and CubeIDE) as listed in https://wiki.st.com/stm32mpu/wiki/STM32MP15_ecosystem_release_note

some useful pages too:

Hi, Patrick!
Thank you very much for your reply. Finally I've got tf-a and u-boot assembled and FIP image generated.
(using this wiki page: https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package#U-boot_-_unpack_and_patch_sources
)
But u-boot load fails with following log:

Hi,

Btw, your fail is within TF-A.

I suspect something not well formed in the uBoot FIP image around FW_CONFIG size.

On Flashing DK2, I see :

INFO:   Loading image id=31 at address 0x2ffff000

INFO:   Image id=31 loaded: 0x2ffff000 - 0x2ffff226

INFO:   FCONF: Reading FW_CONFIG firmware configuration file from: 0x2ffff000

INFO:   FCONF: Reading firmware configuration information for: dyn_cfg

INFO:   FCONF: Reading firmware configuration information for: stm32mp1_firewall

Note that device column = mmc0 mean SD-Card on SDMMC.

To build a Serial-NAND CubeProgrammer Flashlayout, please have a look to https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout#NAND_Flash_memory_with_FIP

Device column should be spi-nand0 and offset to be carefully selected (see also https://wiki.st.com/stm32mpu/wiki/STM32MP15_Flash_mapping#NAND_memory_mapping)
