Hi, all
i'm using OMAP35X EVM board with the linux kernel 2.6.32 maintained by TI.
In my project, i need a gpio pin to communicate to another peripheral FPGA board.(Just one bit tell it starts to work.)
i've surveyed the hardware guide document. But seems that there are no gpio pins on my board.
But i still want to know are there any solutions can be accessed like a gpio pin?
I've tried to use the i2c port by access the SDA line as an gpio but failed....
Also tried to use the J2 two pins jumper.(it is pin-out of gpio_141)
but the schematic doucment tells me: Do not consider this net for OMAP35x Processor Board configuration.
why??
Can anybody helps me??
Thanks a lot!!!
