Hi!
After flashing imx8qmmek board with Zeus image built from manifest imx-5.4.70-2.3.1.xml:
uuu -b emmc_all imx-boot core-image-minimal-imx8qmmek.wic.bz2
Loading a Zeus image, through tftpboot (kernel and dtb), works fine.
But loading a Sumo image, through tftpboot (kernel and dtb), leads to :
mmc0: Timeout waiting for hardware interrupt.

The same procedure, but on a board flashed with Sumo image, used to work fine.
Could it be a uboot/kernel Zeus/Sumo incompatibility?
Thanks!

Hi fabatera
>Could it be a uboot/kernel Zeus/Sumo incompatibility?
in general yes, as each uboot/linux versions should be formally aligned as
described in Release Notes document on linux documentation link
Also it is necessary to follow sect.1.2 System Controller Firmware (SCFW) Requirements
