After the system boots, I would like to slow down the CPU/Memory to save energy. My system is not doing much except logging multi channels of 1200 baud communications to SD card. So most of the time, I would like my system to stay low speed.
If the default speed of CPU is 800MHz, I am thinking to run it at 100MHz after booting. I still need it to boot fast at 800MHz. So how to do that? I am using Petalinux. Regards
