I did use ft2232_write() and ft2232_read(), and it works from the
driver code...
to try it out i modified an existing command: "runtest" and used it as
an interface to the driver ("runtest 1" would read and "runtest 2"
would write some data to the outputs.)
what I would like to implement is a user command to run from the
telnet interface to read and write to the io pins available on the
ftdi chip while set to jtag mode.
if the command were to be called "io": io read/write mask [data], then
i would like to be able to the following from the telnet interface:
io read mask
the previous command would set the pins selected by "mask" to be
inputs, read them, and print their value to the telnet interface.
io write mask data
the previous command would set the pins selected by "mask" to be
outputs and write "data" to them.
i did not find a way to add a custom command in an elegante way...
