Error Flashing first partition: Hello, I have a custom board with STM32mp157c and i'm trying to load the u-boot for ddr testing. I created u-boot basic defconfig with ddr_interactive=1 and

[Lmoio.1]

a tsv file with

#Opt	id	Name	Type		IP		Offset		Binary
 -	0x01	fsbl		Binary		none	0x00000000	u-boot-spl.stm32

I got different error messages:

Hi @Lmoio.1​ ,

Did you already successfully boot the same custom board with Trusted boot chain ?

How did you manage Device Tree customization for you board ?

Can you share Console output during CubeProg execution ?

Thx,

No, I get the same error at partition 1.

For the moment we are using the Device Tree from the stm32mp157c-ev1.

With trusted boot chain, there is nothing in the console.

With basic boot chain, there is:

U-Boot SPL 2020.10-stm32mp-r1-gbde7c9b2f1 (Jun 14 2021 - 10:00:44 +0200)
Model: STMicroelectronics STM32MP157C eval daughter on eval mother
RAM: DDR3-DDR3L 32bits 533000kHz
0:DDR_RESET

Hi @Lmoio.1​ ,

Strange you don't have even a single trace in Trusted boot mode.

You are using stm32mp157c-ev1 DT. I assume then your design is similar or very close ?

Any difference ?

Did you have same DDR reference and configuration ?

I presume you are trying to use Serial USB boot ?

Did you follow carefully recommendation in AN5031 Getting started with STM32MP151, STM32MP153 and STM32MP157 line hardware development for OTG_HS_DP/DM pins and for boot pins ?
