We have a product using an AM3505, with a 26 MHz oscillator connected to the sys_xtalin. We find that the system time (like what you see when you type "date") falls behind about 0.48 seconds per minute. The drift seems very regular, across all instances of this product that we have looked at. I tried playing with the kernel CONFIG_OMAP_32K_TIMER_HZ parameter, but I haven't been able to correct this. Is there a configuration somewhere to specify how the oscillator relates to ticks?
