i've got a different camera with Ambarella chip, i can get into Amboot, but the problem is, it will not stay on amboot, about a minutes it will reboot. And another problem is, it dont have fs command.
Here are some commands that exist in AMBoot:
my question is:
1. How can i stop the board to reboot randomly.
2. How do i backup the partitions before write it with the partitions from other camera?
3. Does the other command can replace the fs command?
The 'nand' command usually has some very useful capabilities - try 'help nand' or 'nand' with no parameters to see what functionality is available.
If it can read a partition to memory, the tftp command should be able to extract it externally.
1. Yes, i set a stopwatch and it is reboot after 30 seconds, and it not enough for me to do anything to restore the camera partitions.
