Hello NXP:

I want to use gpt(General Purpose Timer) to capture external pulse for counting, I know the gpt1 is used by the kernel to generate the ticks for the OS, so I want to use gpt2, but when I access the base register of gpt2 in console by uart, then the OS hangs. 

Can you help me? Thank you!
