[Gumstix-users] Overo CPU > 500MHz ?

[Marco V. <Marco@Vienup.de>]

Dear all,

I am using a Gumstix Overo Air with the preinstalled kernel. At boot time I
get the following output:

So I think the board is currently running with only 500MHz. Can someone
please give me some hints what to do to get clock rates > 500MHz ?
