I recently bought a 64 GB eMMC module (chip on orange board) from Ordoid/Hardkernel but u-boot does not recognize the eMMC.

What I did:

• installed the official Armbian_20.11.10_Odroidc2_focal_current_5.9.14.img.xz with Etcher on SD card
• booted successfully from SD card, eMMC is accessible from within Armbian/Ubuntu
• executed nand-sata-install to transfer the system to eMMC, which completed without error messages
• shutdown the system, removed SDcard and restarted it

 

The serial console displayed the following:

and then tried to boot via network.

 

I then flashed the eMMC with the official Odroid image ubuntu-20.04-3.16-minimal-odroid-c2-20200617.img.xz and the system booted up successfully, so the eMMC module is working fine.

Next step was to try the nightly build (Armbian_21.02.0-trunk.80_Odroidc2_focal_current_5.10.10_gnome_desktop.img.xz, with Etcher flashed on SD, then nand-sata-install) and again the eMMC as not visible in u-boot so the system did not come up.

 

Therefore I set up an Armbian build environment and first tried to use this promising patch for u-boot https://gitlab.denx.de/u-boot/custodians/u-boot-amlogic/-/commit/5ccd5d2cc98224108ae9fb09593a862c9caa5e80 but it seemed not to be suficient.

I then replaced the provided u-boot v2020.10 with the new v2021.01 version and after replacing the kernel and uboot packages with the self compiled ones the eMMC was recognised by u-boot and the system boots from the orange 64GB eMMC module.

The "Card did not respond to voltage select" message is from the missing SD card

 

Therefore I kindly ask to upgrade the u-boot of Odroid C2 to version 2021.01 in the next release.

You only need to do this:
https://github.com/armbian/build/pull/2601 (sometimes there is lots of work, this time I only lost half an hour)

Optional for adding info to release log:
