Hi Enrico,
Thanks for your prompt reply.
For us the 'realpath' command is working fine. The devices do exist at the
respective location. Below are the logs from our end for the post-boot
scenario and the bootargs. It seems RAUC is trying to look for device '
00000000-01' whereas the actual device is '1b325bba-01'. Is there a way we
can configure RAUC in userspace to look for device 1b32bba-01 in place of
00000000-01?
