After unsuccessfully flashing different root-filesystems, I finally
found this note:
If you upload rootfs image that is smaller that previous one it
won't work - you need to attach to bootloader, erase NAND and then
upload your rootfs first:
cu -l /dev/ttyACM0
GTA01Bv3 # nand erase rootfs
This *should* help but I am trying to understand why dfu-util can't
do that? And what do I do if I have no serial interface? Does this
mean I can't ever again flash a (smaller) rootfs?
I have no info on the first question, but about the serial interface.
The commands above actually run over USB. Simply boot the Neo into
uBoot
(hold the Aux button while powering on) and select the option to
use the
console over USB (Move selection using Aux, invoke the selection by
pressing
power). Then plug in the USB cable and run the "cu" command.
Many thanks for your suggestions,
but MacOS X has no cu command :-(
And, I want to automate this all with dfu-util.
BTW: the bug tracker (bugs #419, #719, #726) says it has been solved
by a newer version of uboot - but to my experience
it is not completely solved even by an uboot compiled 19th August.
It looks like that contrary to the warnings on http://
wiki.openmoko.org/wiki/Flashing_openmoko it is NOT optional.
We all should flash a newer uboot first.
