Hi Ian.
Last week I only managed to make it work after I found info from other guy, basically I had to disable the default TS FPGA file, and load only the open core one. Also, With the open core itself without a change I was able to access the GPIO. However, with some tests I found out that the transfer rate from ARM to GPIO is very slow, less than 1.5 MHz. I access the board via telnet or serial terminal and can reload fpga code without reboot. Tests became much more aqgile now :-).
You can find it searching a message from in the yahoo group. "TS-7300 fpga code".
Using a silly fpga code to output a square wave by itself the fpga is able to put 25 MHz with little wave deformation.
I wish I could transfer data from ARM with more frequency than this less than 1.5 MHz...

Lissandro As long as you don't have any device drivers attached to the FPGA hardware, you should be able to issue "load_ts7300" as many times as you like without any problems. Ian T.
