AM5728: Lowest possible Cortex-A15 frequency

Marka Reddy

Part Number: AM5728

we are using AM5728 EVM. we have modified OPP entries in dts to get multiple available frequencies(200MHz,400,800..1500MHz) apart from the default ones. Now my question is what is the lowest frequency supported by the AM5728?

Mark,

The Cortex A15 frequency does not have a lower limit. It can function all the way down to having the PLL in BYPASS.
