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?

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.

Hello everyone. I need lot of help. First of all sorry ,English is not my born language and I am an amateur in terms of VESCs,etc. Some year ago I built myself a skate board with VESC 4,12( this was in 2018) using 2 X3S batteries total 6s. I also used a Turnigy 245v motor. Ran ok for a while. Than I built another battery bank with 40 x 18650 batteries( 10S total) it was perfect. After some time stopped i make it happens again, now with 2 x 6S batteries, total 12 S and 8 amps. I updated firmare using an updated VESC tool and set the parameters. The acceleration curve is not good and it has some failures, like some cuts. I was checking the Motor spec and it seems that cannot support 12S but maximum 10S. I am not sure about the Vesc hardware capacity. Can anyone help to understand and maybe make the right configuration for this combination??? Thank YOU
maybe cut from over voltage, you could check it with the battery 30% charged
