Hi Gunnar,

Unfortunately, we miss code for PLL2 configuration as PLL input.
Though, I'm adding Attie who investigated that point and may have code to get it working.

Hi!

I got a board with the crystal at 25MHz, and need to use the PLL2 as input to the system clock.
I just do not seem to understand the code enough to see how to set the prediv and multiplication for the PLL2
I can choose PLL2 as input to the PLL, and PLL as input to the system clock, but how do set the parameters for PLL2?

Any pointers would be very much appreciated.

Cheers,
