Hi,

We want to check  the Clock frequency of various processor on TI-Netra platform,

Can you please provide the register details that needs to be read in order to find out the clock rate of A8, M3s, IVA, DSS, DSP ?

 

Thanks in advance

Regards,

Srilakshmi

    Hi Srilakshmi,

    http://www.ti.com/lit/ug/sprugx8/sprugx8.pdf

    You can get the details from TRM, section "1.10 Device Clocking and Flying Adder PLL" and "1.16.1.2 PLL Control Registers"

    We are measuring the stock ARM clock at 600MHz on the 'DM814x EVM and 800 MHz on the 'DM816x EVM. Since TI frequently uses these platforms for testing and development, so running faster may take you into uncharted territory. See e.g. advisories 2.0.2, 2.0.32, 2.0.68 in the DM816x errata, available on the product page.

    Note that such problems are unavoidable whenever you have lots of high-performance asynchronous functional blocks sharing memory in a flexible configuration. The devices' lack of arbitration for CPU requests to SDRAM complicates matters in this case.
