Unable to load rootfs, numerous SD card errors

dluberger — Wed, 19 Sep 2018 16:57:47 GMT

Despite the fact that my sd card seems fine, I'm getting lots of errors while the kernel attempts to load the rootfs. Boot log attached. Also, I noticed that while the kernel loads, my LCD screen gradually fades to all white. I'm wondering if this is just a symptom of the kernel hanging up and the LCDIF buffer filling? The issue starts at line 409, where it says mmc0: Timeout waiting for hardware interrupt. Is this related to the card detect line? I tried changing the device tree setting for the card to non-removable but that didn't help.

Hello,

please check your board, using recommendations of the Hardware Development

Guide for the i.MX 6UltraLite.

Perhaps, it makes sense to test memory:

Is it possible to try booting SD card instead of eMMC?

Have a great day,

Yuri

Thanks, I actually figured this out a while ago. It turned out I had disabled something in my defconfig file that I hadn't realized was related to the SD card (SCSI or something like that). The kernel now loads the rootfs.
