flash_can.py not going into boot loader mode

[treaves]

I'm trying to upgrade Klipper on a Manta M8P board that was already running successfully. The latest version of Klipper requires the MCU's be updated as well.

I'm following the steps I found in a closed ticket that I thought were to be able to do this. When I run the
python3 ~/katapult/scripts/flash_can.py -r -u your-uuid
command, it does not report an error and the
Bus 001 Device 005: ID 1d50:606f OpenMoko, Inc. Geschwister Schneider CAN adapter
device disappears. But nothing ever shows up in /dev/serial/by-id/. I also see this in the dmesg output:
[ 284.055674] usb 1-1.4: USB disconnect, device number 5
[ 284.056028] gs_usb 1-1.4:1.0 can0: Couldn't shutdown device (err=-19)

Has anyone overcome this issue?

I'm having the same issue with an Octopus STM32F446. It was working fine 2 version ago. Same problem with flashtool.py and flash_can.py.
