Hi Team, I am working on boot from a USB flash drive and try to flash the data (rfs/appfs) to MMC partitions using RAUC. I am currently facing some issues on the same. The same scenario works well when we boot from NFS and try to flash the data to MMC partitions. By attempting to boot from a flash drive partition that has RAUC and trying to install the bundle to MMC are we trying to do something that RAUC supports or are we missing something? Please find the related logs for USB flash drive based RAUC installation attempt below *root@test:~# rauc install test.raucb * rauc-Message: installing /home/root/test.raucb: installing rauc-Message: installing /home/root/test.raucb: 0% Installing rauc-Message: installing /home/root/test.raucb: 0% Determining slot states rauc-Message: installing /home/root/test.raucb: 20% Determining slot states failed. rauc-Message: installing /home/root/test.raucb: 100% Installing failed. *rauc-Message: installing /home/root/test.raucb: LastError: Did not find booted slot* Installing `/home/root/test.raucb` failed root@test:~# root@test:~# root@test:~# *root@test:~# rauc status* *rauc-Message: Failed to resolve realpath for '/dev/disk/by-partuuid/00000000-01'* Failed to determine slot states: Did not find booted slot root@test:~# root@test:~# root@test:~# root@test:~# *root@test:~# /usr/bin/rauc --mount=/run/rauc service* *rauc-Message: Failed to resolve realpath for '/dev/disk/by-partuuid/00000000-01'* rauc-Message: Failed to obtain name de.pengutronix.rauc root@test:~# root@test:~# root@test:~# *root@test:~# ps ax | grep rauc* 380 ?
