Other Parts Discussed in Thread: OMAP-L138

Hello

I am working on the LCDKOMAP-L138 board and my requirement is I need to interface external FPGA device using GPIO Pins available on the LCDKOMAP-L138 board.

Is ts possible to use it this way?

If it is possible or anyone has tried this technique then please provide me guidance for this problem.

Waiting for the response ..

Thanks and Regards

Hello,

If you want to receive an input from the FPGA on a GPIO pin you may want to refer to the following guide for configuring GPIO. The guide is for AM57xx but the concept is the same for OMAP-L138.

I'm also linking the documentation for the GPIO driver below.

I hope this helps.
