OMAPL138 frequency setting

Other Parts Discussed in Thread: TPS65070

 Hi all,

I have a question on the CPU frequency。

My board power supply chip  is TPS65070 ,  just like the  logicpd design,  and now processor work frequency is 300M.

But now I want to increase the frequency to 475M,  how should I do? (just ONLY need to rewrite the PLL0 configuration? )

The PDF saids  that 475M need 1.3 V power supply but 300M is 1.2 V power supply, so i wanta know  how to solve the power problem?

the last ,if i  increase the frequency, is there  negative effects? Such as instability and so on.....

Thanks for your help
