Is it possible to dump the firmware from an existing controller?JTAG pins is on easy point at the controller board. Problem for me is what i have to do without f-series full dump file?According to reddit, you can replace the motor controller. I think it will be difficult to find the JTAG pins as the the controller is covered in black resin.
you will only be helped by the firmware using ST link
Is the format of the firmware file different when flashing via JTAG than when flasing via Bluetooth? The apps are able to download firmwares from somewhere at least.
