Somebody in the thread at some point said:
| Hello,
|
| I've tried to upgrade software on my Freerunner, but when I'am trying
to enter
| DFU mode it doesn't work. I'am booting from NOR as described here:
| http://wiki.openmoko.org/wiki/Flashing_the_Neo_FreeRunner
| but when I'am runnig dfu-util it only shows "USB Device Firmware Upgrade":
DFU never worked in a straightforward way for me until I wrote a little
workaround script, this one is the u-boot dfu upgrade one I use
#!/bin/bash
../../dfu-util/src/dfu-util -a 1 -d 0x1d50:0x5119 -D u-boot.udfu
if [ $? -eq 1 ] ; then
../../dfu-util/src/dfu-util -a 1 -d 0x1d50:0x5120 -D u-boot.udfu
../../dfu-util/src/dfu-util -a 1 -d 0x1d50:0x5119 -D u-boot.udfu
fi
Somehow it changes VID / PID after enumeration maybe, anyway if you
adapt this script it may help you out.
