Hi ralphy,

Sorry for reviving this old thread. I, too, have a dockstar running with
bodhi's latest kernel and u-boot. I think running Alpine on the dockstar
would really help, given the limited memory on this device.

I've been trying to get Alpine to run on my dockstar for a week, but I
seem to have run into a dead end. I'm kind of new to u-boot, and
troubleshooting is hard without a serial connection.

I have netconsole enabled on a very similarly configured pogoplug_v4,
and here is as far as I get:

--------------------


As per bodhi's installation guide, everything is just on sda1, formatted
to ext4.
No other partitions on the drive. So far, I've tried the following:

Used sodface's armel_genrootfs.sh to generate the Alpine rootfs
Added alignment=2 to uEnv.txt
Played around with /etc/fstab

I would appreciate if you or sodface could point me in the right
direction. Thank you.
