Digging into the code a bit it looks like the FT231X would not be supported by the 'ftdi' driver as that driver is for chips with MPSSE. So that takes me to the ft232r driver and looking at Emard's patch at http://openocd.zylin.com/#/c/4681/ it seems there is no support for FT231X GPIO yet. Any patches out there for FT231X GPIO yet or any pointers to get me started hacking it into OpenOCD?
