hi,

    We are use AM335X and ti-sdk-am335x-evm-05.06.00.00 to design our own pruducts. 

    Now we need to use a HW timer to get 500us timing interrupt accurately.

    And the question is:

    1 As we currently know is that timer 5 6 is used in cpsw, are there any other timer used in ti-sdk-am335x-evm-05.06.00.00?

       which timer we can use?

    2 Is there any examples used timer?

    The CPSW interrupts connections were corrected in silicon revision 2.0.  We should have a new AM335x errata published in a few days which includes silicon revision 2.0 updates.

    I assume your AM335x based product will be using silicon revision 2.0 or newer devices if you are still developing the product.  Therefore, these timers should be available for other functions. 

    I'm not sure when software will be changed to free-up these timers.
