Why don't you use the other serial interface? I wired it as debug port,
you could use it as general IO...

Hi,
When using channel A of the ftdi 2232H as JTAG there are spare pins
available as GPIO.
I want to be able to read/write to these pins.
I've managed to this by modifying ft2232.c (i'm not planning to change
the driver, just wanted to verify it was possible).
I would like to have a command i can manually execute (such as halt,
resume, etc) to read/write to the gpio pins.
What I need is similar to getting a command to manually blink the leds
on a given layout (execute layout->blink @ ft2232.c). The difference
would be that i want to send/receive parameters.
I've been looking around, but everything at levels higher than the
driver seems to only use jtag...
Any tips/ideas on how to do this?
Thanks!

Rodrigo.
