m365-rescue

Python based helper to restore m365 devices. Works on Linux!

The project is based on https://github.com/CamiAlfa/M365_DRV_STLINK.

No firmware files are provided with this tool. You have posess the binary you want to flash.

WARNING: Most of the stuff is untested, be prepared to brick your device and open an issue / PR here :). Thanks!

Usage

You can flash any firmware suited for the device (that you own!) by providing the path to the file as an CLI argument.

Use the -s or --simulate flag to generate an output file specified by -o or --outfile, instead of flashing with STLink.

Use the ble subcommand for BLE related functions. Use the --16k flag to indicate a M365 / Pro device with 16kb RAM (includes most clones). Default is 32k RAM device (Pro2/1S/3). Type ble --help for more help.

Use the esc subcommand for ESC related functions. Use the --gd32 flag to indicate a GD32 instead of the default STM32 MCU. Use the --sn and --km options to set the serial number and kilometer counter respectively. Type esc --help for more help.

STLink / OpenOCD

Connect STLink to the target device and start a openocd session. Then, in a new terminal, enter one of the example commands.

Restore 32k (Pro2..) BLE

python m365resc.py ble BLE134.bin

Restore 16k (Pro..) BLE

python m365resc.py ble --16k BLE090.bin

Restore STM32 ESC

python m365resc.py esc --sn "..." --km 123 DRV236.bin

Restore GD32 ESC

python m365resc.py esc --gd32 --sn "..." --km 123 DRV247.bin

Restore 4Pro ESC

python m365resc.py esc --nb --sn "..." --km 123 DRV022.bin

Simulation

Simulation allows generation of the final output file without STLink connection.

Generate full 32k (Pro2..) BLE rescue file

python m365resc.py -s -o out_ble134.bin ble BLE134.bin

Generate full 16k (Pro..) BLE rescue file

python m365resc.py -s -o out_ble090.bin ble --16k BLE090.bin

Generate full STM32 ESC rescue file

python m365resc.py -s -o out_drv236_stm32.bin esc --sn "..." --km 123 DRV236.bin

Generate full GD32 ESC rescue file

python m365resc.py -s -o out_drv247_gd32.bin esc --gd32 --sn "..." --km 123 DRV247.bin

Generate full 4Pro ESC rescue file

python m365resc.py -s -o out_drv022.bin esc --nb --sn "..." --km 123 DRV022.bin
