The CPU and system clocks speeds are changed with the boot loader (S1L or kick start).
You may need to build a new version of the boot loader with your desired setup.
The Linux kernel has built-in power management and you should be able to enter the
suspend-to-mem state on the LPC32x0 and then wakeup on a specific event (ie, gpio,
SD card insertion, RTC alarm, etc.)
A basic write-up using the RTC alarm is here:
I know this works for the Phytec board, but it hasn’t been tested on the EA and FDI
boards with DDR memory, although the code should be complete.
