how to wipe mtd1 off your pogoplug mobile

[hecatae]

step one, replace ubifs with rescue system,

step two, replace rescue system with openwrt following http://blog.qnology.com/2015/02/openwrt ... obile.html

step three, try to reset rootfs using "mtd -r erase rootfs" in terminal

result, mtd0 valid, but nothing in mtd1,

can I tftpboot the rescuesystem ubifs back to mtd1 using serial?

What exactly is the issue you're trying to solve?

"mtd0 valid" means that your uboot is okay? If so boot Debian/ALARM from USB and do whatever you want with the internal nand - rescuesystem/openwrt.

as far as I can tell my uboot is okay, but nothing will boot, usb, sdcard, ubifs...

so I'm stuck as after 5 usb sticks and 4 sd cards, there is definitely something wrong.

Did you setup netconsole? That would help determine if uboot is okay and if your uboot environment parameters are correct.

If not, you'll need a serial console connection. Worst case, uboot is messed up, and you need to recover via UART booting.

Use bodhi's kwboot found here - https://www.dropbox.com/s/bx1usk1bzt87ufh/kwboot

yes i setup netconsole,

serial tells me host 10.10.10.5 is not available,

hang on:

He is missing those variables because he installed 2015.04 arch uboot and modified bootcmd, probably taking the line from bodhi's environment along with mixing in crap from other posts in the forum. Of course it will not work.

OP, make your choice of the U-Boot you want. You absolutely do not need to edit environment if you install 2015.04 uboot.
If you want to see the logic behind those long lines in arch uboot, refer here: https://github.com/moonman/u-boot/commi ... fb841ac5f1

He got netconsole, and in IRC I had him run this to reset his environment.
