Hello, I am looking at two questions now. 1) How to see the AM65x core frequencies at runtime from Linux? At the moment, I only know how to show BogoMIPS. I will have another answer on this in a couple of days. 2) How to update CPU frequencies for both clusters? Let's take the uboot dts file arch/arm/dts/k3-am654-r5-base-board.dts in Processor Linux SDK 6.0 as an example. To assign clock rates for multiple PLLs, I would update the file like so: a53_0: a53@0 { compatible = "ti,am654-rproc"; reg = ; power-domains = , ; resets = ; - assigned-clocks = ; - assigned-clock-rates = ; + assigned-clocks = , ; + assigned-clock-rates = , ; ti,sci = ; ti,sci-proc-id = ; ti,sci-host-id = ; u-boot,dm-spl; }; I am not sure if "resets" also needs to get passed both clocks, double checking on that as well. Regards, Nick
