We are considering reducing SOC and ARM power consumption.
I would like to change the clock root frequency of AXI, AHB, IPG from the information written in the Reducing Power Consumption of page 5 of AN 5383, but I can not boot with either fix.
There seems to be some limitation on the clock root frequency of AXI, AHB, IPG, but can you give me relevant information?
When entering Wait mode or Deep sleep mode, we have to adjust the frequency of the above 3 clocks.
Is there any change procedure and sample source code ?
