[Gumstix-users] OSCR timer

[eduardo b. <ef...@ya...>]

Hi all.
   
  I can write and read GPIO's using mmap perfectly in my gumstix connex 400xm-bt. 
  My problem is with OSCR register, when I read it always gives back the same value although the developers's manual says: "The OSCR is a 32-bit counter that increments on rising edges of the 3.6864 MHz clock. This counter can be read or written at any time."
   
  When i try to write on it, my program freezes and the gumstix crashes. I'm not using interruptions in my program, just want to initiate and capture a precise and fast count.
   
  Can i use this register freely? there is any condition to use it? How can i initialize the OSCR appropriately?
   
  Any help or idea is welcome.
   
  Thanks in advance
