Seeking the SampleProject for STM32MP157 with zephyr

[dotaituan]

Hi Everyone

I am new member of ST device, now I face problem regarding SPI communication on STM32MP157F-DK2 kit.
I am using the latest zephyr RTOS version (which primarily supported STM32157C-DK2 kit).

Problem:
- The Master Out pin does not output the data

Note:

- The CS and CLK is working normally 

If anyone have the Zephyr reference, I am appreciated.

Best regards,
Tuan Do

Hello,

Do you check if the GPIO is not already used by the Cortex-A7 running the Linux?
