I was unfortunate enough to get a VESC without a bootloader, but after some research, I think I can flash it myself. I’m pretty confident about the process, but there’s one issue that I’m running into. I’ve poured over all the threads and documentation I can find, but I can seem to find the pin out information so I can hook up my ST-Link correctly.
Was wondering if any of you had that info on hand.
I’m trying to run a dual motor setup. I got both my VESCs within the last month from TorqueBoards.
The process that you suggested @ZmasteR worked seamlessly for one of my VESCs, but I can’t get the 2nd VESC to take the firmware. I thought that it might not have a bootloader, but I haven’t had success using VESC tool to flash a bootloader to my problem VESC.
@ElBandido How many seconds do you wait before you reconnect after you update new firmware? I’d wait about 5-10 seconds. Usually, you’re computer will make a sound and you’ll be able to reconnect.
That worked great for one of the two VESCs that I have, but the other one hasn’t been cooperating.
If I’m not having any luck with Vesc tool, is it reasonable to think that if I reflash the bootloader with an ST-link, that I could get the update to the VESC?
I’ve had a hard time figuring out how the pin-out from the VESC correlates to the pins on the ST-link. Other than that, the process seems pretty straightforward.
Is there a data sheet you could point me to that I’m missing?
