STM32MP157DAB1 custom board eMMC recognition problem

[jaehoon]

Hello, I built FIP artifacts following wiki, `STM32MPU Developer Package`, 5.2. Installing the OpenSTLinux BSP packages.

And I could get binary files:

1. TF-A binary: tf-a-stm32mp157d-smp4-mx-optee-emmc.stm32
2. OPTEE binary: tee-*.bin files
3. u-boot binary: u-boot{,-nodtb,-dtb}.bin files

I did not build linux kernel yet. I want to check PMIC's 1.35v output in current step, because I've read somewhere in ST wiki that works when TF-A is flashed.

But Cube Programmer disconnected from the device before doing something.  <-- This was soldering problem. after resoldering, its fixed.

and even more, eMMC is not detected in cube programmer.

eMMC recognition problem.

No partitions are related for eMMC. should I flash first partition and FSBL?

Or how can I check this problem?

Hi,

did you load a correct flashlayout file to CubeProgrammer ?

https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout#e-E2-80-A2MMC

Here is an example on how to flashload a board (here it is SD-Card, but will be similar for eMMC, apart different flashlayout file)

Hello, Ah, I tried to flash my boards with customized TSV file.
and it includes just custom TF-A binary and FIP binary. but Cube programmer returns following message:

18:13:56 : Download in Progress:
18:13:57 : File download complete
18:13:57 : Time elapsed during download operation: 00:00:00.662
18:13:57 : RUNNING Program ...
18:13:57 : PartID: :0x01
18:13:57 : Error: Start operation failed at partition 0x01
18:13:57 : Error: TSV flashing service failed

And then, Cube programmer is crashed to desktop.
Is this a problem on TF-A's device tree? @PatrickF

hi @jaehoon ,

worth to look at board console output if any messages. TF-A is probably crashing.

Did you check your DDR settings/behavior with DDRFW-UTIL ?

Regards.
