tf-a and u-boot custom compile fails

ASkri.1 · ‎2021-05-27

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)

Hi, Patrick! Could you please be more specific about FW_SIZE? I've just executed steps from Wiki. About flashlayout - I've copied it from the emmc version and I know that I need to spacifi spi-nand0 device to load. And, yes, I've read a wiki-page about flash-layouts :) But at this step I want to see U-BOOT loaded with qspi-nand recognized... Thank you in advance Looking forward for your reply пн, 31 ма�? 2021 г. в 17:37, ST Community :

Could you please try this (adapt the path if required):

fiptool info ./sources/arm-ostl-linux-gnueabi/FIP_artifacts/fip/fip-stm32mp157a-stm32mp151-dk1-mx-trusted.bin

example of result when using the scripts from wiki.

Secure Payload BL32 (Trusted OS): offset=0x100, size=0x1347C, cmdline="--tos-fw"
Non-Trusted Firmware BL33: offset=0x1357C, size=0xCF9D8, cmdline="--nt-fw"
FW_CONFIG: offset=0xE2F54, size=0x226, cmdline="--fw-config"
HW_CONFIG: offset=0xE317A, size=0x1D0A0, cmdline="--hw-config"
TOS_FW_CONFIG: offset=0x10021A, size=0x4748, cmdline="--tos-fw-config"

Seems you FW_CONFIG is not well defined. I'm not a strong SW guy, Maybe try:

regenerate TF-A (as described in https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package#TF-A_-_regenerate_TF-A)
when regenerate uBoot (as described in https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package#U-boot_-_regenerate_fip_image_within_new_u-boot), insert "make mrproper" e.g.

pushd $WORKDIR/sources/arm-ostl-linux-gnueabi/u-boot-stm32mp-[0-9]*/u-boot-sources
make stm32mp15_trusted_defconfig
make mrproper
make -f ../Makefile.sdk DEVICE_TREE=<device tree> DEPLOYDIR=$FIP_DEPLOYDIR_ROOT/u-boot FIP_CONFIG=" trusted" FIP_BL32_CONF="tfa," all
popd

Please find fiptiil info output below: /FIP_artifacts/fip$ fiptool info ./fip-stm32mp157a-stm32mp151-dk1-mx-trusted.bin Secure Payload BL32 (Trusted OS): offset=0x100, size=0x1347C, cmdline="--tos-fw" Non-Trusted Firmware BL33: offset=0x1357C, size=0xCFA18, cmdline="--nt-fw" FW_CONFIG: offset=0xE2F94, size=0x4F27, cmdline="--fw-config" HW_CONFIG: offset=0xE7EBB, size=0x12A91, cmdline="--hw-config" TOS_FW_CONFIG: offset=0xFA94C, size=0x4258, cmdline="--tos-fw-config" It looks similar to yours... Not clear with stm32mp157a-stm32mp151-dk1-mx-fw-config.dts file (TF-A). According to this wiki page: https://wiki.st.com/stm32mpu/wiki/How_to_configure_TF-A_FW_CONFIG It has some complex structure. But mine (generated by CubeMX) have just one include: // SPDX-License-Identifier: (GPL-2.0+ OR BSD-3-Clause) /* * Copyright (c) 2020, STMicroelectronics - All Rights Reserved */ #include "stm32mp157a-stm32mp151-dk1-mx.dts" Maybe this is wrong? In this case where to get the correct fw-config file? Thank you in advance Looking forward for your reply пн, 31 ма�? 2021 г. в 18:51, ST Community :

There was a problem: stm32mp157a-stm32mp151-dk1-mx-fw-config.dts file - "stm32mp15-ddr-512m-fw-config.dts" should be included.

Thank you very much for your support - I will go on with kernel loading :)

Next.

Finally I have modified flash-layout file and tried to download all to nand:

Here is flash_layout file - it matches to mtd partitions above:

#Opt

Fortunately all flashed correctly :) Now I want to boot from qspi flash :)

But setting BOOT0-2=111 gives no result - only science in console output..

I can check spi ins activity during boot - there IS activity during a few seconds. So, at least it is trying to boot.

Could you please give me a hint again :)

Thank you very much. Today is a lucky day :)

Hi,

If fail in BootROM, PA13 will toggle at about 5Hz (open-drain, need external resistor to watch it) and should go back to USB DFU.

See https://wiki.st.com/stm32mpu/wiki/STM32MP15_ROM_code_overview#Debug_and_error_cases

Please provide BootROM traces https://wiki.st.com/stm32mpu/wiki/STM32MP15_ROM_trace_analyzer, got after the fail.

Otherwise, it could be TF-A which crash once loaded.
