You will need the Dfu-util to make a backup of your existing image.

As when flashing, you will need to be in U-Boot in the NOR Flash. Log into the NOR uBoot menu and select Set console to USB. Now you will be able to flash, make backups of your Freerunner or query the Freerunner with dfu-util.

NOTE: On a Windows host, omit the "./" or "sudo ./" that precedes the commands listed on this page


THIS WILL TAKE AWHILE. The rootfs will take significantly longer than the kernel.

./dfu-util -a kernel -R -U good-kernel.bin
./dfu-util -a rootfs -R -U good-rootfs.jffs2

Here is what my successful output looked like...

on the host PC:

$ sudo ./dfu-util -a kernel -R -U good-kernel.img

Despite the fact that there was a device status with state=dfuERROR, everything seems to have worked.

on the FreeRunner:

DFU: Switching to DFU Mode
DEVICE_CONFIGURED: 1
Starting DFU Upload of partition 'kernel'
DEVICE_CONFIGURED: 1
Starting DFU Upload of partition 'rootfs'

I could backup the kernel of my GTA02 but trying to use this method to backup the rootfs failed several times....
