6678 ethernet clock range

Which example are you trying to run ?
NDK examples ?
Able to get the IP address and just not able to ping ?
Have you modified the clock related platform code for new clock ?

Let check with HW guy on this new clock 240MHz for PASS.

In case of example, it doesn't matter. It will be ok if I can run client or helloworld project in 240MHz SGMII clock. I can get the IP and just not able to ping.

I set some changes in gel file such as:

#define PLL1_MULTIPLIER 8 (because my input DSP clock is 120MHz(not 100MHz))

SGMII_SERDES_CFGPLL = 0x00000051; (because my input DSP clock is 240MHz(not 312.5MHz))

Thank you so much.

Armin,

Please refer the C667x PLL Clocking spreadsheet which consists of all the peripheral clocking with their limitations.

Please note, this is preliminary version and yet to be released public.

Hi Senthikumar

I know that the ethernet can work with 156.25, 250 and 312.5MHz. My question is can ethernet work with 240MHz or not. If yes what changes I must do?

Hi SenthilKumar

Thank you so much. So I must provide 250MHz clock for Ethernet.
