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.

Sending bootloader jump command...
Bootloader request command sent
Flash Success

An issue was introduced recently when some deprecated code was removed, as mentioned it should be fixed now. The OP appeared to have some kind of driver issue, hopefully BTT resolved that.
