Building

Make sure to adjust ~/ssh-keys according to your configuration:

SHELL=bash kas-docker --ssh-dir ~/ssh-keys build meta-trenchboot/kas-pcetb-base.yml

Change a directory to build/tmp/deploy/images/pcengines-apu2. Find the tb-minimal-image-pcengines-apu2 files with extensions wic.gz and wic.bmap. Copy them to the apu platform (for example through ssh or memory stick). At the platform, check device (/dev/<dev> ) of the drive to be flashed:

fdisk -l

Then flash the drive with bmap-tools:

bmaptool copy --bmap tb-minimal-image-pcengines-apu2.wic.bmap tb-minimal-image-pcengines-apu2.wic.gz /dev/<dev>

Example output

# bmaptool copy --bmap tb-minimal-image-pcengines-apu2.wic.bmap tb-minimal-image-pcengines-apu2.wic.gz /dev/sda
