C4 doesn't boot any Ubuntu images on eMMC

Post by bastiffi »

Hi,

I cannot get my new C4 to boot with any of the default Ubuntu images with eMMC. It's the old v0.3 8Gb eMMC for C2 and it works fine with C2.
The eMMC also boots fine with C4 with armbian. The Ubuntu images boot fine with C4 with microsd. They also boot with microsd even when the eMMC is attached.

Any ideas?

Did you flash ubuntu-20.04-4.9-mate-odroid-c4-hc4-20210128.img.xz image with Etcher?

BTW, what is the color of your eMMC module PCB?

Hi,

Let me jump into the discussion, as I am involved in the project...

Yes, we flashed all images (including the cited one) with Etcher.

The color of our eMMC module PCB is red. The sticker "8" on it is a pink circle. So the card is actually a "Ubuntu for C1" one.

The red eMMC modules must be compatible with C4 and N2 series.

Anyway, I've found an old red PCB eMMC module in our office.
We will test it and get back to you in a couple of hours.

The red eMMC module is not compatible with C4 while other Orange and Black eMMC modules boot fine. :o
It stuck at the u-boot stage.

Code: Select all

MMC init failed

We will try finding a root cause of this incompatibility issue. It may take quite long time though.

No problem, we'll get a newer module. Thanks for the quick replies!
