Hi TI,
How to setup TDA4AL to support a/b rootfs ?
like..
partition:
mmcblk0p1 rootfs_a
mmcblk0p2 rootfs_b
When slot =_a , load rootfs_a to booting
When slot =_b , load rootfs_b to booting
If TDA4AL can support a/b rootfs, we can do a/b update for rootfs.
When system run at rootfs_a, we update image into rootfs_b.
After rootfs_b updated, we switch slot from rootfs_a to rootfs_b to boot.
Now I know how to add rootfs_a and rootfs_b partition.
And I know how to flash rootfs.ext4 into rootfs_a or rootfs_b.
I have no idea about how to load rootfs_a or rootfs_b to booting
Is there any suggetion for this, thanks.
Thanks
Jiahao
