Cant update firmware, can't check serial number

Hello everyone,
I am using an odrive v3.6 56v. when i try to update the firmware via : odrivetool dfu, i get the following code:

ODrive control utility v0.5.4
Waiting for ODrive…
Found ODrive 209030725432 (v3.6-56V) with firmware v0.5.3
Checking online for newest firmware… found v0.5.4
Downloading firmware v0.5.4…
Putting device 209030725432 into DFU mode…

This keeps on going.

Does anyone know how I could fix this?

Kind regards

Where did you buy this device?

yeah i bought it on aliexpress :)). Is there a way though to update the firmware though because except for not being able to opdate, the board works great.

@Wetmelon

I actually have the same problem, but I bought the device from your shop.

I noticed that the encoder calibration isn’t stored in memory (as I assume it should be), so I gave a shot at updating the firmware.

Any idea why this could be happening?

You can try flashing with the RUN/DFU switch in DFU, or you can use the STM32CubeProgrammer tool to flash the device if odrivetool dfu isn’t working.

hi ı have a same error and ı try what you say but didnt work, ı try to stm32cube already, how can ı set serial number does anyone know
