NPi-STM32MP157C DTS for Linux

I have been trying without success to use the stock buildroot v2024.04 stm32mp157c_odyssey_defconfig with the NPi-STM32MP157C board. I have a Seeed SoM STM32MP157C plugged into it.

The buildroot image boots, but there are errors with programming the e.MMC and the Ethernet PHY cannot be found.

I am trying to use this stock image as a guide to get it working…

https://files.seeedstudio.com/linux/ODYSSEY–STM32MP157C/stm32mp1-debian-buster-console-armhf-latest-2gb.img.xz

It uses an stm32mp1-seeed-npi-base.dtb, however I cannot find the DTS for that published anywhere.

Is this DTS available? I also noticed U-Boot / SPL are using the STM32MP157C-DK2 Discovery Board definition. Is that the correct one for this configuration?

Thank you,
Maury

Hi there,
I may out in LEFT field , but I saw somewhere it works best or most of the time if the EMMC is flashed with a tool as opposed to the buildroot.? Nice board though.

Are you flashing the system into the sd card? As far as I know, you need to configure additional things to be able to use Wifi
