Generic eMMC Flasher fails on newest BBone-Images (Ubuntu)

[orgua]

Activating the flasher in /boot/uEnv.txt halts the BBone on reboot (heartbeat stops).

It seems the /dev/mmcblk# devices have been renamed or moved. I see spidev#.# and dev/disk/... now.

Update

the sd-card is present, but eMMC is missing? when I remember correctly both were present on older images.

Setup

• latest image 2023-09-28 (also 08-17) from https://rcn-ee.com/rootfs/ubuntu-armhf-22.04-console-v5.10-ti/
• copied to sd-card and booted from it
• unchanged kernel, but also fails with 4.19.94-ti-r74

@orgua pretty sure i debugged this last week.. what's the output of:

sudo beagle-version

Thanks for the feedback! I had a a chance to try this on a bunch of BBone Green - PCB version 1.0. Four of them are 3y old, but untouched & fresh out of the box. Two were older. All 6 failed / hang with the activated flasher.

It would be odd if all of these are broken? The eMMC-IC is present though.
