[ts-7000] I/O, kernel mode...

[Lissandro <>]

Hi

I´ve being struggling with the 7300 board in order to make a small software that
would make a faster use of GPIOs.

Well maybe I should try other interfaces, but anyway my question is.

- While having a 200 MHz ARM running in the board, so far I was able to make I/O
changes using the sample code and mmap that have reached nearly 13MHz speed
(say, a 7MHz or so "square" wave output). I think one should be able to put out
something like a 50 MHz sq wave or even more, doing some direct I/O. In order to
accomplish that, I should run the software in kernel mode? Or is there any other
way.

Thanks :-)
