Zynq UltraScale+ Shutdown Routine

Jump to solution

Hi All,

I want to power off linux and than power down everything else on the Zynq chip.

I have a push button interrupt controller connected to PS_MIO (this GPIO is avaliable for PMU)

I want to use XPm_SystemShutdown or XPm_SelfSuspend from:
https://www.xilinx.com/support/documentation/user_guides/ug1199-zynq-power-management.pdf

I am not sure what module should run this function.
Is it RPU or PMU?
What is a safe way to turn off linux?
Do think that im using correct approach to the problem?

Thanks,

Anton
