CNC3018 Grbl Offline Controller Ali Firmware


Hello, I have an offline controller for a CNC3018 Arduino Woodpecker Board, shown in pictures (source internet)
Buy playing with the firmware, I managed to brick it
Unfortunately my backup of the original firmware is lost
Does anybody has this firmware or wants to read it out
It is a STM32F103RBT6 MCU on board and can be read with STLlink v2 with the SW connections
the order is +5V, SDClck, SDIO, GND, and setting is slow speed 480khz
Tnx 4 help

No it is not.
It is an APM32F103RBT6

The APM is mostly compatible with the STM but there are differences.

A quick search for "arduino woodpecker" gives lots of results relating to GRBL and apparently there are some versions of GRBL floating around that work for that hardware.

Tnx DP, for answer, but does it help me ?
off course not... just corrections...
What I need is firmware and some helpfull tips or someone can read it , with an SWD programmer
And look at the attached picture.. what shoud it be ?
it is the old version from 2018 and not the new

Tnx for any helpfull messages.
