I would like to manually modify the content of the
/data partition from a generated yocto image. I mounted the partition using the block offset, changed some data there, compressed and flashed the image with
bmaptool. Unfortunately, this changes a checksum which
bmaptool complains about.
Is there a tool such as
mender-artifact that allows to modify that partition?
EDIT: I just gave it a try to run
bmaptool create on the (uncompressed) image. The generated
.bmap file contains just a single line in
<BlockMap> whereas the original hat around 15 entries. So, I guess this does not work just like that?
EDIT: I successfully flashed the image and booted the device. Also file system expansion of the
/data partition works as expected. Are there things that can go wrong with regard to future updates this way or do I just have to live with the reduced writing efficiency because of that single
