Question
stm32mp135D-odyssey fails to find rootfs when booting from SD Card
The kernel is complaining that the specified root partition (identified by the PARTUUID) is not found or isn’t valid, and this is happening at the kernel level rather than in U‑Boot. In other words, U‑Boot is simply passing the kernel command line (which includes something like:root=PARTUUID=e91c4e10-16e6-4c0e-bd0e-77becf4a3582) to the kernel, and then the Linux kernel itself is trying to locate that partition during its mounting phase.
please find the boot logs attached.
