Problem booting Overo Tide at 720MHz

Hi list,

a couple of days ago I was posting a similar issue where Linux wouldn't start after u-boot. I am trying to boot a recent kernel using Steve's omap-3.2 branch on an Overo Tide based board.

A recent checkout doesn't boot and hangs after u-boot hands over to the kernel. After some digging I figured out that this has something to do with the OPP settings for running at 720MHz.

After commenting out omap3_opp_enable_720Mhz() in opp3xxx_data.c the kernel boots fine.

Does this work for all others?

Seems to work fine for me.

Give the binary here a try and let me know if it works for you:

If it does then perhaps it is a defconfig issue. If not, then I need to dig up a Tide to try to reproduce.

Nope, doesn't work either. The funny thing is that it works for the omap3-pm branch which has the 720MHz thing included, too. So maybe the workaround is just hiding something else?

Could you send me the complete processor version string from the u-boot banner so that I can try to use precisely the same processor/version?
