How to read the clock counter (CCNT) of PXA270 processor?
Posted: Mar 27, 2006 @ 2:11pm
I'm writing a small assembly routine to read the clock counter (CCNT) from
my Pocket PC (PXA270 processor).
I used the following assembly code:
MRC p14, 0, R0, c1, c1, 0
Unfortunately, all I got was a constant number (86334131) while it
was supposed to change over time.
What's wrong? Please help me.
