Firmware update under Linux

Hello,

I'm trying to write Deviation dfu to Devo8 under Linux using dfu-util 0.6. No success. Is it possible?

I did the following:

dfu-util -d 0483:df11 -a 0 -D deviation-devo8-v1.1.2.dfu

Tried with -R option as well. It seems to upload data but does not leave DFU mode then.

I'm using dfu-util 0.6 on OS X 10.8, works fine.

Leaving DFU mode through dfu-util doesn't work, though, but flashing, then manually resetting the transmitter works.

From the Makefile:

Hm, reset did not work in my case. Even removing the battery had no effect. It just returns into firmware update mode immediately.

Maybe I have to try JTAG to debug the issue.

Tried Windows, still no success even with native Devo firmware. The TX just does not leave upgrade mode at all even after removing the battery.

Now going to use JTAG to reflash everything including the bootloader.

I'm pretty sure the upgrade failed and the checksum is wrong. For some strange reason dfuse does not see the TX anymore while dfu-util still does. Looks like the TX's bootloader is stuck in some strange state preventing it from normal upgrade.

I think I'll better treat the CPU as empty and reflash everything. At least it will be readable then. Probably I'll end with a custom bootloader
