Hi guys.
I was stupid enough to update my FW to FOCBOX Unity when i have the VESC single motor controller 4.12 HW.
Now it's bricked.
Is there any way to rewrite to whole thing again when i can't connect to it?
Any way to erase it and reinstall maybe?
Thanks.
You should program it by st-link(x) programmer via swd interface. 2x7pin header is used for programming. From top left corner 5 pins should be enough for programming. (3V3, SWC, GND, SWD, RST) These pins is to be connected to ST-LINK (v2) programmer. You should have a full fw or a bootloader for Unity.

Thanks but I just want to make sure that this procedure is doable for VESC 2 or what some call VESCX for a single motor.
Do you guys have a good recomendation for a reliable ST- link?
Uv
Any clone from ebay. Do not connect 3.3v! CLK, IO, GND is enough. If you have a second vesc, you can also use the second vesc as a programmer. Vesc tool has a feature called SWD PROG.
