What's the freqency for this DM6467

I have got a EVM for DM6467, but i don't know the DSP frequency for this EVM. How can I know the freq. for this EVM? The Device name is TMS320DM6467CZUT$N30-8BA0K3W. Thanks a lot! Is there any command for check the DSP frequency?

    the frequency of dm6467 is set in ubl；you can find the code to set the frequency （PPL），and see it by printing the value of  register！

    Do you meaning the PLLM register? The value in PLLM was 0x00000015 when I checked the register via CCS, so I think the frequency is 594MHz. But I also want to know how to check the C64x+ frequency in Montvista Linux, how can I get the C64x+ frequency in linux?

    I am not sure if there are any built-in functions to allow you to do this in Linux, but in a very similar fashion, reading the value of PLL registers should allow you to determine the speed of c64x+.  You can write a kernel driver to read these registers if you need to; alternatively, if there is a standard linux command to get the ARM CPU frequency, then the DSP (64x+) frequency would just be twice the ARM frequency
