How to use HPS internal clock in Agilex 7 SOC

[Veerappan]

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. 

Thanks,

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

Hi Veerappan, 

Sorry for the delay, was discussing your 3 forum issues with our team. Could you give more details like what other changes in your configuration and the steps you use to build, program and read back the register, additional logs /design files would be helpful? 

I will try to see whether I could source an Agilex 7 SOC on my side to replicate based on your configuration.

Thanks

Regards

Hi khtan,

I am using ARMDS to program, debug the uboot and read register value. Actually My question is how to configure HPS internal oscillator as source for both main and peripheral PLL.   

Thanks,
