local build TF-A crashes during boot, STM32MP157A-DK1 kit

EAlex.1 · ‎2020-11-13

Hello

i'm trying to get started with the STM32MP1 env, and I'm having some issues building the trusted firmware boot image, after following the steps from: https://wiki.st.com/stm32mpu/wiki/STM32MP15_TF-A

I'm, building it with the following commands, on the v2.2-stm32mp branch, with gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04) , no changes on the git branch:

make distclean
 
make CROSS_COMPILE=arm-linux-gnueabihf- ARCH=aarch32 ARM_ARCH_MAJOR=7 PLAT=stm32mp1 DTB_FILE_NAME=stm32mp157a-dk1.dtb FDT_SOURCES=fdts/stm32mp157a-dk1.dts DEBUG=1 STM32MP_SDMMC=1 dtbs
 
make CROSS_COMPILE=arm-linux-gnueabihf- ARCH=aarch32 ARM_ARCH_MAJOR=7 PLAT=stm32mp1 DTB_FILE_NAME=stm32mp157a-dk1.dtb FDT_SOURCES=fdts/stm32mp157a-dk1.dts DEBUG=1 STM32MP_SDMMC=1

I can see the following messages on the serial console:

The SD-CARD image is build with create_sdcard_from_flashlayout.sh, based on the following script:

#Opt	Id		Name		Type		IP		Offset		Binary
-		0x01	fsbl1-boot	Binary		none	0x0			arm-trusted-firmware/tf-a-stm32mp157a-dk1-serialboot.stm32

P		0x08	rootfs		FileSystem	mmc0	0x05284400	st-image-weston-openstlinux-weston-stm32mp1.ext4

U_BOOT (also local build) and the other images are ok, as it will boot properly if I use tf-a-stm32mp157a-dk1-trusted.stm32 instead of the locally compiled binary

Are there any knows issues regarding TF-A build ?

I can't see anything related to the GCC version in https://wiki.st.com/stm32mpu/wiki/PC_prerequisites

(edit reason: wrong gcc version)

Thanks,

Alexandru

Hi @EAlex.1 ,

I'm a bit surprise by your build command and value of CROSS_COMPILE

Simple command line to properly buid a TF-A in provided SDK is :

make -f Makefile.sdk TF_A_CONFIG=trusted TFA_DEVICETREE=<board>

I guess you should rather look at page :

https://wiki.st.com/stm32mpu/wiki/STM32MP1_Developer_Package#Building_and_deploying_the_TF-A_for_the_first_time

Rather than https://wiki.st.com/stm32mpu/wiki/STM32MP15_TF-A which expose a solution for expert likely more error prone.

Hope it help,

Olivier
