hello all

Do any one know how can i set the operating frequency of ARM core on beagle board to 600 MHz. I am currently running it at 500 MHz with kernel 2.6.28. If I need to use another Uimage then pls let me know which image i should use and is there any changes to be made in the operating voltage then pls let me know about it.

Thanks in advance

500MHz -> 600MHz:

Yes, you want to change operating voltage, too. But I can't remember to have seen any patch to do this properly.

It's in the PM branch (which only allows 550MHz), if you build linux-omap-pm with OE you get a 600MHz capable kernel.

I believe the CPU frequency is set in u-boot.
