Dear Champs,

Is it possible to set PRU clock to 200Mhz in AM623x?

If so, could you please provide a guide to set 200Mhz PRU clock?

My customer is using Linux SDK v8.6.0.

Thanks and Best Regards,

SI.

Hello Sung-il,

Yes, it is possible to set the PRU clock to 200MHz on AM62x.

Please refer to these two FAQs. I wrote them for PRU_ICSSG devices, so the details will be slightly different. However, the same concepts should also apply to the PRUSS on AM62x:

If these resources are not sufficient, please provide detailed feedback on the missing information, and I will take a closer look next week.

Regards,

Nick
