i.MX8MP booting fail

JasonFSYang — Sat, 12 Apr 2025 14:56:21 GMT

Hi Sirs,

I am using Flexbuild to build an image for imx8mp, after flashing emmc by following command

flex-installer -d /dev/mmcblk2 -m imx8mpevk -f firmware_imx8mpevk_emmcboot.img -b boot_IMX_arm64_lts_6.6.36.tar.zst -r rootfs_lsdk2412_debian_desktop_arm64.tar.zst

I get an error message when boots from emmc

-----------------------------------------------------------------------------------------

however this image works fine if boots from SD card

question 1 : Which error will cause this message?

question 2 : Should I use UUU to flash emmc?

Any help would be appreciated.

HI @JasonFSYang

Please use the uuu command flash the image to the emmc and see the result
