Re: Can't flash smaller root-fs through dfu-util?
Dr. H. Nikolaus Schaller [EMAIL PROTECTED] [2007-08-19 21:23:08]: 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? http://bugzilla.openmoko.org/cgi-bin/bugzilla/show_bug.cgi?id=419#c7 ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

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. - John ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

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?

Nikolaus The problem is that many of us don't have a debug board, and it's a bit scary to flash a new uboot which could brick the device. It would be nice if some uboot builds were blessed so that we know we can safely flash those without bricking the neo. ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
