Can not find ODrive

After flash ODrive using sudo dfu-util -a 0 -s 0x08000000 -D build/ODriveFirmware.hex,odrive can not be found.
and I can not use the command, sudo odrivetool dfu build/ODriveFirmware.hex,to flash ODrive.
what should I do?

Same issue here. Just bricked by ODrive last night. I’ll try again tonight and update if I find anything useful.

Are you getting an error code? You can try updating with a different DFU tool (see this page)

$ sudo odrivetool dfu

it seems that odrivetool can’t find the device…
