I'm using Boundary devices u-booot version 2016.03 and linux kernel - Linux-boundary 4.1.15.

 

I'm can see following message while loading the kernel. What is the problem here ?

 

Could you please tell me how to set the ENET PLL (PLL6) 100 MHz (SATA) PFD output in order to access the registers in the PCIe IP block ? Is that the problem here ?

 

Can you tell me where should I set above clocks ? Is that in uboot ? Can I have file location ?

Thank You,

Peter.
