note, you’ve indicate the target as bootloader if you did not specify -t option in the nvbootctrl command-line.
please switch between rootfsA/B with this command, $ sudo nvbootctrl -t rootfs set-active-boot-slot <SLOT>.
the default retry counts for bootloader is 7-time, and the default retry counts for filesystem reloading is 3-time,
please check SMD info, i.e. smd_info.rootfs_AB.cfg to configure the settings.
for example, < MAX_BL_RETRY_COUNT 7 > and < MAX_ROOTFS_AB_RETRY_COUNT 3 >
We kept bootloader count and rootfs retry count as below,
< MAX_BL_RETRY_COUNT 7 > and < MAX_ROOTFS_AB_RETRY_COUNT 3 >
but sometime system taking 3 reboots, 4 reboots or 8 reboots to change the slot and to boot from other partition,when we crash the one of the rootfs partition.
So we need to know on which parameter reboot count is considered.
