Hello.
I am on porting STM32MP135F-DK Discovery Board source to STM32MP133D based customizing board.
With bitbake build, the firmwares work well with STM32MP135F-DK.
But with our developing board, it stuck on BL2 boot with panic.
The main difference is like below.
1. PMIC is connected to i2c5 not i2c4
2. DDR ram size is changed from 512MB to 256MB
3. There is no display controller. (LCD).
4. SDCard is changed to eMMC.
I changed tf-a-stm32mp/fdts/stm32mp135f-dk.dts file to match difference.
And followed the instruction of the link below.
When I build after some changes, build commands are like below.
bitbake -C compile tf-a-stm32mp optee-os-stm32mp
bitbake tf-a-stm32mp optee-os-stm32mp -c deploy
I used STM32CubeProgrammer to download the firmware.
Boot log was like below.

Would you give an advise?
Thanks for reading.
