We are using the AM3715 with a ubuntu installation. The system has been set to 1GHz and read back of the settings confirms this is now set.
I have set SPI out freq to 20MHz, but on a scope I see 12MHz.
If I set usleep(250) I see 416us on on the scope.
Both are out by 0.6 - this would be the ratio of 600MHz main clock and the one currently set at 1GHz.
Is there a setting somewhere which still thinks the clockrate should be 600MHz?
Any clues on where to look for this?
