dunfell var-som-mx8m-mini sd card boot stuck at waiting for root device #28

Closed mhuangwm closed 3 years ago

mhuangwm commented 3 years ago

Hi, I'm following a guide according to https://variwiki.com/index.php?title=Yocto_Build_Release&release=RELEASE_DUNFELL_V1.4_DART-MX8M-MINI

I created the sd card image:

zcat tmp/deploy/images/imx8mm-var-dart/fsl-image-gui-imx8mm-var-dart.wic.gz | sudo dd of=/dev/sdX bs=1M conv=fsync

and when attempting to boot via SD card, the kernel is stuck at Waiting for root device /dev/mmcblk1p1..

I know that root is at /dev/mmcblk1p1 from the ls mmc command:

u-boot=> ls mmc 1:1

<DIR>       1024 ..

           45795 imx8mm-var-som-symphony.dtb

however, when i try to switch to that partition, I errored out:

u-boot=> mmc dev 1 1
Run CMD11 1.8V switch
switch to partitions #1, ERROR

I tried this with multiple SD cards just in case. Am I doing something wrong?

Here are the kernel logs:
