Forum Post: RE: Changing from AM335 720MHz to 1GHz

Oh okay, no problem : ).  Yeah U-Boot doesn't seem to have any issues, it sets the 1GHz speed and voltage and runs without a hiccup. When i try to boot linux though it just locks up during uncompression or occasionally will throw an uncompression error caused by: "invalid distance too far back".  Reading the MPU voltage at this point in time it is still 1.325, so no issues there.

The only way i can get the kernel to boot is by turning the speed back down to 800MHz or lower before callling boot in U-Boot.  I am currently playing with my kernel init stuff (arch/arm/mach-omap2/board-am335xevm.c) assuming the issue is there somewhere and hoping i can pinpoint it : /.
