eMMC not recognized

Gordon · October 2016

I just got the up board with 2GB RAM and 32GB eMMC. The eMMC doesn't show up in the BIOS nor in the EFI shell.
Attached is the snapshot of the EFI shell screen.
Do I need to change the BIOS setting to enable the eMMC?
Thanks,
Gordon

There might be a broken initialisation (e.g. grub corrupted, or file system not loading)

The next step is partially documented here https://up-community.org/wiki/Firmware
(you might need to plug-in a usb stick with the OS installation if it is a ext4 file-system corruption).
You might just need to restart the efi subsystem from this msdos-like environment.

type the following commands

fs2:
dir
cd \efi
dir

there is a file name with the suffix .efi. enter it,
It reinitializes the missing boot part and re-enter grub from existing file system, or fresh install from usb key.
(the fresh install will overwrite the existing emmc, and re-create a proper grub initial setup)

An other possibility : you never installed anything on the board

To get started
Download an operating system : https://up-community.org/wiki/Software#Operating_Systems
Put it in a usb device e.g. as described here https://up-community.org/wiki/Installing_ubilinux
Plug the usb device into any usb connector

Reset the board, press f7
you will get the choice between entering the bios or the install from the usb device.

It might not work (why ??? why ??) and you enter the screen you mention
from that stage type "exit", you will be asked for a bios password, just press the reset button of the board, this enters the bios, press esc to exit the bios and this brings you to the install from your usb device.

And then you will never see that screen again :-)

It's a brand new board with nothing installed.

It works fine after installing the ubiliux via USB.

Thanks,
