EMMC Device Tree Path Not Found during U-Boot

[devinschubert14]

Hi everyone,

I was finally able to get to the kernel and use the shell using the sd card (yay!). However, we want to boot from the emmc (sd card was for dev purposes but we want only emmc) and I am running into an issue. Here is my boot log from booting on emmc after flashing with DFU:

I have attached my U-Boot dts and kernel dts. I am using a custom Yocto dev environment with the meta-st-stm32mp layer included (scarthgap branch, version: openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06 ).
