Handle booting failure for u boot ( Debian )
I am working on OTA Update for a device.
I have an sd card with 3 Partitions. mmcblk0 is the disk and mmcblk0p1, mmcblk0p2 ,mmcblk0p3 are the 3 partitions.
Partition mmcblk0p1 has a uboot configuration ( uEnv.txt and other files required for booting ). Partitions mmcblk0p2 and mmcblk0p3 have a Debian OS.
Partition mmcblk0p2 and mmcblk0p3 are used as an active and inactive partition. When an update comes it is downloaded and installed to the inactive partition. Once it completes user reboots the device and the user is booted into the last inactive partition ( The partition on which update is performed )
I am using uEnv.txt to change the boot configuration i.e. If I want to boot from mmcblk0p2 I can give
mmcargs=setenv bootargs console=tty0 console=${console} ${optargs} ${cape_disable} ${cape_enable} root=/dev/mmcblk0p2 rootfstype=${mmcrootfstype} ${cmdline}
in the uEnv.txt
This works when the update is successful
But if uEnv.txt gets corrupt due to any failure or the partition gets corrupt then the device won't boot from either of the partitions. ( i.e. OS )
Is there any way to handle this issue? ( For example, if partition mmcblk0p3 is updated ( But it gets corrupted due to some reason ) and now it's trying to boot in that partition and fails to boot from that partition, in that case, is there any way I can boot back from mmcblk0p2 )
