Ubuntu eMMC image

wood-brandon · March 1, 2022, 2:33pm

Hi,

I have seen there is an updated version of the ubuntu images released via this thread. I understand these run off the micro SD card, and am trying to flash the image to the eMMC. I noticed in the setup steps as per the install guide that there seems to be specific images with ‘eMMC-flasher’ as part of the name, which I can’t find in the new directory.

Just wondering if this ‘flasher’ image is required specifically to flash the eMMC, or if there is a way to flash the normal images. For reference I am using a BB black industrial.

Cheers

Hi @wood-brandon yes, i stopped doing discreet “flasher” images, it artificially doubles my server hosting size… (and thus “upload”, so things takes 2x…)

this should work… but please let me know if it doesn’t!!! So from the command line…

sudo apt update
sudo apt install bb-beagle-flasher

Then configure for BBB microSD → eMMC:

sudo cp -v /etc/beagle-flasher/beaglebone-black-microsd-to-emmc /etc/default/beagle-flasher

Then 2 modes…

Basic user-mode…

sudo beagle-flasher

bootup “auto” flasher mode…

sudo enable-beagle-flasher

Hi @RobertCNelson

This works a treat - thanks for your help and detailed reply.

Cheers

Tobias_Hochguertel · June 8, 2022, 10:03pm

I tried as first “sudo enable-beagle-flasher” and got no output or message. and a help menu (-h) is not available. Then I used the command: “sudo beagle-flasher” and got a lot of output.

While the second command was running, I came to the idea, maybe the first command just set up a switch so that after rebooting the BB-B the flashing to emmc is starting from the bootup process?

I would like to get there some informations with “sudo enable-beagle-flasher”, some output like: “Hey Dude, the copy to emmc flag got set up. Reboot now, and let the BB-B work.”.

Getting no output is always unclear, and not explaining what happened, and what is to do as next.
