Error While Initializing MMC Card

lifesaglitch · February 2018

I just received my Up Board and installed Ubilinux. However, upon booting I am presented with the following MMC error:

I'm unclear how to begin troubleshooting this. I can't tell if this is a hardware or software problem.

Hi lifesaglitch,

Looking in these forums it appears this may be a ubilinux 4 issue:
https://forum.up-community.org/discussion/2346/up2-mp-8g-128g-emmc-speed-issue

I wasn't available at the time of that report and I haven't experienced this myself yet. Following @Bartek's footsteps, there are two workarounds you can try:

Changing the eMMC Max Speed parameter in BIOS as shown in the first post
Installing Ubuntu

Please let me know if any of those fixes your issue, as that would indicate a software bug.

Thanks!
