Ubuntu – Ubuntu core webdm alpha for Beaglebone Black not booting

beagleboardubuntu-core

I have tried the flashing SD card for Beaglebone Black with 'Ubuntu Core WEBDM' image i.e. 'ubuntu-core-WEBDM-alpha-02_armhf-bbb.img' as mentioned in the steps here.

But the system is not booted. I have the following error captured in serial console. Thanks in advance for your suggestions and help.

From console:

Net:   <ethaddr> not set. Validating first E-fuse MAC

It seems uEnv.txt (on your SD card) is wrong. Change ${bootpart} to ${mmcdev}:${mmcpart}, i.e.

# where to load initrd
initrd_addr=0x88080000
# load Snappy environment and call into Snappy boot after processing this file
uenvcmd=load mmc ${mmcdev}:${mmcpart} ${loadaddr} snappy-system.txt; env import -t $loadaddr $filesize; run snappy_boot

This should fix the error "File not found snappy-system.txt" and allow U-Boot to continue.
