Switching root from Flash to RS-MMC without Flasher
On my Nokia 770, I use a 128mb rs-mmc card formatted with ext3 to hold the development rootfs.
The most obvious way to boot off the rs-mmc card is to use the Flasher tool with this command line:
./flasher –set-root-device mmc
And to resume normal operation:
./flasher –set-root-device flash
However flasher needs a PC at hand- cal-tool to the rescue!
For development (on mmc):
chroot /mnt/initfs cal-tool -R mmc
For release (on flash):
chroot /mnt/initfs cal-tool -R flash
N.B. This command requires xterm and root permissions on both your release and development (so you can switch back) images.
