Hello,

We have developed a custom board based on MPC8640D processor

In a board we are using serdes 1 - x8 PCIe and serdes 2 - SRIO port.

In temperature testing the processor resets at ambient 55 deg cel temperature testing with in 1 hour.

We have done 2 -3 iterations of the heat sink.

From processor point of view, I want to use and Implement  Dynamic frequency switching for Core, in order to reduce the power dissipation.

Kindly help how I can enable Dynamic frequency switching for MPC8640D

Regards,

Amit
