hello seeky15,
please check below steps to update the RootFS info variable.
this should update the slot-A status to normal after system reboot.
for example,
# cd /sys/firmware/efi/efivars/
# printf "\x07\x00\x00\x00" > /tmp/var_tmp.bin
# printf "\x3c\xc0\x01\x00" >> /tmp/var_tmp.bin
# chattr -i RootfsInfo-781e084c-a330-417c-b678-38e696380cb9
# dd if=/tmp/var_tmp.bin of=RootfsInfo-781e084c-a330-417c-b678-38e696380cb9; sync
# chattr +i RootfsInfo-781e084c-a330-417c-b678-38e696380cb9
# reboot
FYI,
we’ve plan to create separated UEFI variables for rootfs A/B status, so user may rest them in UEFI menu.
it’s schedule for next JetPack public release.
thanks
