How are you powering the VESC? The target voltage seems strange.

yeah, I was expecting something more like 3.3 V.

I've tried both with the the V-ESC powered with 36V and no power to the V-ESC, just the USB power to the discovery board.

I've got some connectors coming tonight that will let me try a shorter programming cable(I'm currently using a sensor wire and adapater that is around 15 cm long).

I'll report back if that cures the issue.

I'm still bothered by the flash drive not coming up, seems like that would be an easy work around.

I tried again with a programming wire that is about 6 cm long, no difference.

Any ideas?

Flashing the binary into the F411 on the discovery board is an "exercise" to see if you have the software and commands set up correctly.

The next step is to remove the jumpers hook up the cable to the target VESC and program the VESC. If that does not work, it would seem your connections are not correct or your VESC is broken. The error messages you get in THAT case are more important than showing you succesfully programmed the '411 on your discovery board.
