busblaster 4.1V and OpenOCD

October 14, 2020, 05:55:11 am

Hi I have a 4.1 that I got years back when it was recently released. I am trying to get it up again now and I keep getting errors from OpenOCD.

The following is what I get when I use the instructions in your manual. What changes should I be making if any to the cfg file now that ft2232 is depreciated for ftdi?

openocd -f busblaster.cfg
