Hi!
I’m using OMAP3530 720MHz and the software from http://www.angstrom-distribution.org/demo/beagleboard/. It is not Beagle and there are no magic pins to detect BB revision. But the board has BB C3 based schematics, at least 99% from that.
In u-boot I setenv mpurate to 720 and during the kernel booting I see the following:

Angstrom further works, but I don’t consider this as a good behavior. Any suggestions?
