Yeah, goddamn it. Through a very unfortunate series of events, I accidentally uploaded Unity fw to my focboxes. Now, when I try to connect on BLDC Tool, I get this:
…and since I can’t connect to it, I can’t replace the fw with the correct version.
Am I officially in ST-LINK territory or is there a more graceful alternative recovery procedure (that works nicely on a mac)?
I mean if that is too much of a problem for you than yes…
It’s super easy to do and you just need a working vesc based esc for it.
If you don’t have header for the focbox pcb you can solder the wires on temporarily or go with the needle thing (I wouldn’t do that needle thing thou )
I’ve got another two focboxes running Ack 3.102, which I notice doesn’t have the SWD Prog feature. I’ve got another one lying around somewhere. I’ll check that.
And whether I use another VESC or the STLink, I need to solder JTAG/JST headers on as you described earlier here?
Fuck me. Such a simple mistake to make. Such a PITA to fix.
