Hi All, I am trying to clock down the MIPS Processor by changing the PLL setting. So I can change the CPU Freq at runtime just switching between the PLLs. During my try, after changing the PLL Freq, the board is stops running. I feel, it is due to change in SDRAM Refresh rate. Is it right ?? Any body tried this, Kindly share exprience with me. Like how to reprogram the peripherals with-out affecting the operation etc.. Kindly CC to me. Thanks, -- Bharathi S
