M365 DRV FIRMWARE downgrade via stlink
Posted: Thu Oct 03, 2019 8:34 am
Hi community
Just bought a brand new m365 classic, build date around may 19.
Unfortunately, i got it with firmware 1.5.4.
Reading a lot how to downgrade to 1.3.x and upload a custom fw, but all methods failed.
It seems that for the newest m365 scooters, the magical stlink method is not working anymore - i am getting "cannot connect to target*. All wires are ok, no shortcuts, all links are between stlink usb device are following the pcb marks and not the metal ones, etc. The board has all 4 leds on but its not working. Seems to be on more people with new scooters.
So in the end, i want to ask you, if i can upload a custom firmware from m365.botox.bz site via connecting stlink directly to DRV/ESC with m365rec.exe tool and bypass the bluetooth connection.
I saw that ESC has also clk/dio/gnd and 3.3 or 5v on motherboard.
