How to use HPS internal clock in Agilex 7 SOC

Hi,

   How to use HPS internal oscillator as a source for both main and peripheral PLL.

I tried by choosing the Internal oscillator in a general configuration in Platform Designer device->device and pin options. But it does not work. How I verified this by reading the main_pllglob register. The address is  0xFFD10048. The VCO source is kept at 0 even though I chose it as an internal oscillator.

Hi Veerappan,

Apologies for the long delay in replying , was on medical leave for 2 weeks and my forum account access got revoked, just manage to regain access this week.

 

I will look into this case and feedback to you later, once again I'm sorry for the long response delay.

 

Thanks
