I’m making a build with two Vesc 6’s that was working okay until I went to update the firmware. One worked flawlessly but the other one got its power disconnected in the process. Now I’m with one Vesc functional and the other one only with the blue light on, and I can’t connect to it with the usb port, which means it’s probably bricked.
I bought a ST Link V2 clone to connect to it, but it kept giving an “could not connect to target” error even after checking the wiring many times (Gnd - Gnd, Swclk - Clk, Swdio - Io). I tried connecting the St link to the working Vesc as well but I had the same problems, so It’s not an issue with the Vesc itself.
I also tried connecting one Vesc to the other and using “SWD Prog” through the Vesc Tool but it also gave target errors.
What am I doing wrong? Do I need to buy a original St link like an Nucleo board?
