Thanks for your clarification.
If your kernel and rootfs partition is just one UBIFS in a bigger UBI volume,Yes, I use one UBIFS for 4 partitions, RO rootfs, RO kernel, RO DTB
and RW application, no write for RO partitions, that should be safe, I
your device is somehow connected to a network. So what I suggested was havingThe reason we don't update kernel and rootfs because the size of
kernel and rootfs is too large, it is hard to download 60MB image OTA
via 4G CAT M1. If we are going to change to use 4G CAT1 or higher
speed, I'll use either RAUC or SWUpdate, which one is the most popular
for embedded system using uboot and UBFIS?
Thank you very much.
