DM6446 GPIO driver?

Dennis C
Intellectual 360 points

Hi, our board is closely based on the DM6446EVM TI demo board. We have a few LEDs that are driven by GPIO pins on the processor. My app would like to open the gpio driver and write to it to control the LEDs. However the DM6446EVM DVSDK MV kernel does not seem to have a GPIO driver to do this. Am I missing it? Any sample code or pointers would be appreciated.

Thanks

    Hi,

    Controlling GPIO is not a big task. It requires a handful of register access. You should be able to pick this from the user's guide.

    That said, the driver is capable of accessing GPIO. I do not know the details on doing that. Will forward your question to the Driver/Linux forum.

    Best regards, Zegeye
