Hi all,Could please you sent your modification the next time as patch or text snippet?
Within this modification, linux.efi could contain its own root parameter.
I don’t know if it is a right way, please let me know if you have some suggestions. Thanks in advance.With a fixed root parameter you need to ensure
that the partition you update is on all devices the same, e.g.
A -> B -> A
1.0 -> 1.1 -> 1.2
For example this does not work:
A -> A
1.0 -> 1.2
The customer needs to update first to 1.1 and B before updating to 1.2.
In cip we have solved this issue of root fs selection by adding a uuid or use verity checksum to identify the root file system corresponding to the linux.efi. This allows us to update independent from the root parameter.
