How long is a time-stamp OMAP l138

I am using the DSP/BIOS Logging, and if I look into the ROV->LOG and then my log I see time-stamps like 3742262535 and 3742264007. Between those stamps are 1472 ticks. How much time is this? Or how long is a time-stamp tick?

    Someone else who's more familiar with your device could probably give you a quick answer, but I think a Timestamp tick is usually equal to 1 cycle. So divide by the clock rate of your device to get seconds.

    There's also a target API you can call to get the frequency [Edit: This code only works in BIOS 6; it sounds like you're using BIOS 5]:

    Types_FreqHz freq;

    /* Get the Timestamp frequency. */
    Timestamp_getFreq(&freq);

    System_printf("Frequency hi: %d, lo: %d\n", freq.hi, freq.lo);
