Referring this post, I tried to disable reboot on Assert error but then my nvbootctrl status is something like this with slot 1 : unbootable:
sudo nvbootctrl dump-slots-info
Current version: 35.6.0
Capsule update status: 0
Current bootloader slot: A
Active bootloader slot: A
num_slots: 2
slot: 0, status: normal
slot: 1, status: unbootable
Serial boot logs bypassing ASSERT error :
�I/TC: Reserved shared memory is disabled
I/TC: Dynamic shared memory is enabled
I/TC: Normal World virtualization support is disabled
I/TC: Asynchronous notifications are disabled
