STM32MP131 waiting for UUID

[devinschubert14]

Hi everyone, I made it past the bootloader stages but am now running into errors with starting the Linux kernel. I have an eMMC and SD card but I am trying to only use the SD card for now. I have completely removed the eMMC from device tree and removed the machine.conf settings so eMMC should not be used. When I get to the Linux kernel boot I get stuck at:

[    5.630620] Waiting for root device PARTUUID=e91c4e10-16e6-4c0e-bd0e-77becf4a3582...
[    5.737317] mmc1: error -84 whilst initialising MMC card
[    5.885839] mmc1: error -84 whilst initialising MMC card
[    6.045167] mmc1: error -84 whilst initialising MMC card
[    6.236994] mmc1: error -84 whilst initialising MMC card
[    6.242418] mmc1: Failed to initialize a non-removable card

I am confused if I am stuck because of waiting for root device or mmc1 is not being intialized (even though it shouldnt be trying since I disabled it) and I am able to read/write to SD card just fine until this point (and can see with u-boot shell). I have attached my dts files and log from boot and any help is appreciated as I feel I have messed with the dts a bunch and cannot get past this stage. I am using the Distribution package with the "scarthgap" branch.

Thank you,

Devin

I am unable to send .zip files because of my company IT and only allowed 3 uploads so here are the rest of the dts files. Thanks

I found the solution. Had to a little deeper dive into Yocto, but I discovered I am not using the distribution package, I am creating my own Yocto directory and I have the 'meta-st-stm32mp' BSP layer added. Since I was cloning directly from the Github page, I had the latest commit which seems to cause an error (maybe needs to be looked into). After changing my repo to the same release commit as the distribution package, I successfully got into Linux shell. (yay!) I can't get the eMMC to work still but I will make another post. Thank you!
