Hello there,
Has anyone been able to edit an ubi/ubifs successfully?
I’m working with the RM551E-GL and December firmware on Ubuntu.
So far I’ve figured out how to generate a simulated nand flash pretty much identical to what the Mtd is on the real nand.
I’ve been using ubiformat to flash the sysfs.ubi to the simulated flash then ubi attaching, and mounting ubi0_0
I can then edit the rootfs and then use mkfs.ubifs on the mount point. I then ubinize.
I’ve also tried using dd on the ubi0_0 (ubifs) device and MTD block (ubi)
I’m able to boot the edited sysfs.ubi after flashing with Qflash once but if I mount -o remount,rw / the modem is guaranteed to not boot next time and be stuck in Sahara dump mode. (DM port only)
