Hi,
In the below post I was told to ask this question in this forum.
http://e2e.ti.com/support/embedded/tirtos/f/355/t/360858.aspx
Regarding the SYS/BIOS Sys Tick, we understood that the DMTimers(2-7) will be used as the tick timer.
As mentioned in the above post the SYS/BIOS uses 32KHz as the default timer frequency for AM335x DM Timers,
And we would like to know what is the accuracy of this system tick(DMTimer).
Can we assume the accuracy of DMTimer will be equal to the external clock source CLK_M_OSC(crystal) -in our case 24MHz?
In our sample application(on AM3352) using Clock_getTicks() , we found that system tick
is not that accurate. For every 1 second time there is an extra delay of 7ms.
Best Regards
Prad
