I have a OpenWRT device that I'm wanting to backup the partitions to see if I can make any customization or enhancements.
I followed https://openwrt.org/docs/guide-user/installation/generic.backup, however, I have two partitions that seem to not want to let me copy data from them.
Backing up mtd14 (log_data) dd: can't open '/dev/mtd14ro': Resource busy Backing up mtd16 (rootfs_data) dd: can't open '/dev/mtd16ro': Resource busy
Not too worried about mtd14, but I'm assuming mtd16 is where the fun items are. What would be the best way to copy this out?
