Hi, A few months ago, Christian Lamparter suggested to me the use of get_clock_counter() in the carl9170 firmware code for time measurement purposes. I just got back to that, after a long period of other things to do instead. According to the results of a few tests I've been running yesterday, it looks that this clock is 44Mhz, not 40Mhz, nor 80Mhz. According to Christian, the clock source, as accessed through get_clock_counter() is stable and does not depend on calls to clock_set(). This is further corroborated by the definition and use of the AR9170_TICKS_PER_MICROSECOND *constant* in timer.h. But still, how comes that constant is 80 then? I'm obviously missing something here. I would be really thankful to anybody who could explain how these clocks/timers work and how they are supposed to be used.
