AM6421: Can OSPI be configured as a free running clock?

Hello Ryan,

Ryan LIU said:

As the title suggests, I want to configure OSPI to be a hold clock when free.

Do you mean to say that you want the OSPI clock to be running freely independent of it being used?

Hi Vaibhav,

Yes,  Even if there is no data is being exchanged, I still want the clock to always exist.

On other chips, I have seen this kind of setting. Is it achievable on the AM64x?

Hello Ryan,

I guess I would need to check with the HW expert on this.

I am assigning this thread to the correct HW expert and you can expect responses in sometime.

Could you please share the use case.

The clock may not have been characterized fpor any other use case other that the OSIP interface.

Hello Ryan,

I checked with the design team internally and there is no provision to generate continuous clock.

If you could please provide the use case, i can check with the team if there are  any alternate recommendations or suggestions.

Hi Sreenivasa,

The current case: using the OSPI interface to communicate with the FPGA, and the FPGA expects a continuous clock.

Hi Sreenivasa,

This conclusion is of great help to our project.

Thank you very much for your support.
