fw_utils have the correct setup, a manual call of fw_utils
shows the correct environment of uboot.
I fixed this problem with a script, starting before the rauc daemon,
forcing the mmcblk3bootX devices to enable read/write.
Why do I need to set the "force_ro" to 0, before rauc can access the u-
boot environment?
Why RAUC does not handle the "force_ro" after start?
Attached the script, which is triggered before the rauc daemon.
#!/bin/bash echo 0 >>
/sys/block/mmcblk3boot0/force_ro
echo 0 $gt;> /sys/block/mmcblk3boot1/force_ro
sorry for being a bit unresponsive, but I was only rarely in the office the last
weeks. Did you resolve your issue?
Is that intentionally that you have the environment in the eMMC boot partitions?
Don't you loose the state after updating the bootloader?
We had a similar question as issue on GitHub some time ago:
