bricked by nandtest

[weary]

hi..

i ran nandtest on my plug, and that turns out to be very destructive. now it won't boot at all anymore (nothing showing up in the serial terminal, and only one green led).

i am guessing the nandtest erased all the nand, so i don't have u-boot anymore, is that correct?

Also, i can't get the installer/runme.sh to work. It gives the output shown below. It is similar to the output shown in other threads, but it has the added 'Error: cpsr contains invalid mode value - communication failure'.
Anyone who can tell me what is wrong, and how to fix it?

Regards.

Code:

run nandtest without option -k will erase everything in the device you point to.

Depend on your openocd version, v2 or above you need to modify board/guruplug.cfg in the proc guruplug_reflash_uboot {} the line nand erase 0 0 2 to nand erase 0 0 0x40000 and in the proc guruplug_reflash_uboot_env {} the line nand erase 0 2 4 to nand erase 0 0x40000 0x80000.

Once you modify the file you can run the runme.sh to see if you can get a successful flush. if it did not succeed then try a few more time. unplug the power in between failure to reset the plug sometimes help.

Good luck
