Bricked my Odrive 3.6? Firmware update problem


Just tried to update my v3.6 to the newest RC firmware RC2 v0.5.1.

(The original need for firmware update is related to can-bus, and I was adviced to update to 0.5.0, but I couldn’t find the HEX file for it.)

During firmware update, I get this:

(base) C:\Users\Magnar Tharaldsen>odrivetool dfu ODriveFirmware-v3.6-24V.hex
ODrive control utility v0.4.11
Waiting for ODrive…
Found ODrive 20763370304B (v3.6-24V) with firmware [unknown version] in DFU mode

You are about to flash firmware [unknown version] which is the same version as the firmware on the device ([unknown version]).
Do you want to flash this firmware anyway? [y/N] y
The configuration cannot be backed up because the device is already in DFU mode. The configuration may be lost after updating. Do you want to continue anyway? [Y/n] y
Erasing… done
Flashing… (sector 0/6)

–> 187 raise RuntimeError(“An error occured. Device Status: {!r}”.format(status))
189 def read_sector(self, sector):

RuntimeError: An error occured. Device Status: (0, 2, 0, 0)

Now the Odrive won’t boot up and connect with odrivetool, what to do? :stuck_out_tongue:

This is what the DFU switch is for. :slight_smile:

It will force it to enter the bootloader immediately on power on, for cases just like this.

Yes, I needed to use the switch for my second, third and forth attempt, but, it fails with different error each time.

Maybe I need to test another hex file?

You may need to try a different DFU tool (see here
