Hi,
I am trying to verify that the buttons on the development board are received by the kernel.
I have enabled CONFIG_INPUT_EVBUG but I see nothing printed to the console when I press the buttons.
I also noticed that the touchscreen is not working (I see a pointer but it does nothing). This worked on the demo that shipped with the board but is not working with 4.2.0.7 kernel and filesystem.
On the hardware side I have probed the TCA6416. I can see the button press pulling the line low but I do not see an interrupt generated.
The driver is initialized with .polling = 0.
I also tried to plug a mouse in to the USB input but it complained (via messages to the console saying cannot enable port and cannot enumerate device).
So lots of questions:
1. Any help with the touchscreen? Any ideas how to debug it? I don't need it for my application but I thought perhaps this is a sign of a common input issue.
2. Has anyone used the TCA6416 in interrupt mode? The default is .polling = 1. I am wondering if the devices registers are configured properly to enable the interrupt.
3. Pin muxing? I'm very familiar with pin mux configuration in my usual RTOS environments as I set up the registers myself but I'm not sure how this is done in Linux. I'm wondering if that pin is driven by the microprocessor.
Thanks!
Ken
