OMAPL138 on 456 MHz

Hi Guys,

I would like to let the OMAPL138 (using the ARM only) run at 456 MHz as opposed to the 'default' 300 MHz. I have the appropriate gel-files to do this and I can get it to run at the desired speed. However, when running at 456 MHz my UART (interrupt) does not work anymore. Does anybody know whether I have to change anything else?

Thanks in advance!

Best,
Jeroen
