Which Bafang CAN controller uses which processor?

I wonder if there is an overview for modern Bafang CAN bus controllers already. I screened the firmware files in this library and have some controllers on my workbench, perhaps someone has more information?

For the M620 and M820 there are the links to STM32F10x standard peripheral library files in plain text in the firmware files, so I assume, this processor family will be used....

CRS10F HUB version 1.0 NXP S32K142H

M400 CRX10BC version 1.0 NXP S32K142H
M400 CRX10BC version 2.0 STM32F10x (according to bin)
M400 CRX10BC version 2.1 STM32F10x (according to bin)

The M400 Hw version 2.0 and 2.1 the STM 32F10x is mentioned in the bin file
in the same way as your code picture for the M620

The HC32F460 seems to be a quite similar to the GD32F303, same peripheral registers as the STM32F103, but faster and with FPU. I have no experience, if a GD32 firmware would run 1:1 on the HC32....

The open firmware should be portable to all this STM32F103 like derivates quite easily, if Bafang uses the same pin function on all processor variants...

What program do you use to open .bin the firmware files?

You should ask in this thread, this guys seem to have done the job...

"FAKE TAXI Project" - the modified original firmware for Bafang M820 motor

Hi all, I'd like to present a first public version (11.01.2026) of FAKE TAXI firmware for Bafang M820 motor. Link: Proton Drive File: FT_2026_01_11_public.zip SHA256: 60c785e7010da3314eff8d91130a45da5c33051d7e1ef8006375dfe4bfd2f856 Inside the archive, you'll find a readme file with all...

But everything, that is settable by the BESST/Canable tool, will not be hardcoded in the firmware file, but stored in a virtual EEPROM at the end of the flash memory. If I change the max speed from 25 to 30 kph on my hub motor controller, I can see, that the memory changes in two bytes on page 120 (offset 0x03C000)

FW files for CRX- and MMG- motors appear to be scrambled or compressed. They do not have any string traces in plain text.
