Cannot read/write Keyboard register in Pandaboard

Hi,

I am using CCSv5.2 along with XDS100v2 for debugging Pandaboard. I have created a CCS project and have been trying to perform read/write operation on Keyboard registers but CCS is not able to read  registers. It gives an error of unable to read.

However i am able to read/write Pad control and core registers.

I am attaching snapshots of the same. Please suggest solution for this problem.

    Aniket,

    I was not successful in accessing the keyboard controller registers on my Pandaboard as well. However, that does not mean a bug.

    Several peripherals do not allow their registers to be accessed unless they are powered up. Also, some peripherals also require system registers properly configured to allow access to these.

    Unfortunately I am not an expert on the OMAP4 device to have an example code that enables the keyboard controller - for that you will have to check the suggestions from the experts on the device forum.

    Regards,

    Rafael

    Hi,

    Your are right.. After configuring proper system registers i am now successfully able to access keyboard registers.

    Thank you.
