How to build Yocto Image

The flasher image can be build with kas build ava_flasher.yml See the Documentation for more details.

How to flash WIC image

The wic image can be flashed to the USB stick with the following commands, where /dev/sdX a path to the target USB stick:

sudo bmaptool copy \
    --bmap build/tmp/deploy/ava/adlink-flasher-image-ava.wic.bmap \
    build/tmp/deploy/ava/adlink-flasher-image-ava.wic.gz \
    /dev/sdX

The wic image can also be flashed to the NVME drive using a USB stick with the adlink-flasher-image:

1. Attach the USB stick, (re)boot the board and select the proper USB drive in the UEFI Boot menu.
2. Select: 'USB Boot (If Drive is present): COM-HPC AVA Yocto Image'
3. Copy the *.wic.bmap and *.wic.gz images to the board.
   1. The files can be copied over the network from the build machine with e.g.:

      scp build/tmp/deploy/ava/adlink-flasher-image-ava.wic.* \
           root@<BOARD_IP_ADDRESS>:/tmp

4. Flash the wic images on the NVME drive with:

   bmaptool copy \
       --bmap /tmp/adlink-flasher-image-ava.wic.bmap \
       /tmp/adlink-flasher-image-ava.wic.gz \
       /dev/nvme0n1
