Hi, When looking to the set-up of the FoxBoard, then one can see that with the default settings only one pin is left for IO or interrupt purposes on port PA.
The rest of the pins are claimed to control the LED's, spy the switch and also control ttyS2 (4 pins of PA are used for DTR, DSR, DCD and RI signals). In the kernel configuration, I disabled serial port 2, since I don't need this port. After recompiling the kernel, I saw during the boot process that ttyS2 has indeed disappeared. I assume the 4 pins of PA have become available now as IO again. How can this easily be tested just to be sure I can use them as IO or interrupt again? Best rgds, --Geert
