I have a little problem with dfu-util and my new Freerunner.
I thought I'd make a backup of my Neo's filesystem before flashing new
images onto it, so I tried to use dfu-util in upload mode to transfer
the content of the Neo's flash to my desktop PC. Backing up the kernel
partition works, but when I back up the rootfs partition dfu-util
transfers about 247MB and then dies with dfu_upload error -84, while
the phone immediately reboots. It always dies at the same position, but
I'm not sure whether the backup is complete or not.
Just wanted to say that I'm having the same problem (and same
questions): I was able to upload 258076672 bytes (=246 Mb), but then
dfu-util dies with dfu_upload error -16, and the FreeRunner reboots.
This is on Mac OS X.
Further details: I've tried it on my desktop and on my laptop PC, with
Ubuntu 7.10, Ubuntu 8.04 and a grml live-cd, with various dfu-util
binaries and one built from SVN, but the error appeared every time. The
phone was hooked up directly to the host (no hub or something), U-Boot
version on the phone is the originally installed 1.3.2-moko12 from May
Any ideas what's wrong?
At least one other person (you?) has indicated a similar problem at
http://wiki.openmoko.org/wiki/Pre-Flash_Backup. Any ideas, anyone?
