mimxrt1050-EVK(B) Changing System Clock

[michaelsmorto]

Is there a way to change the system clock and its dependencies at run time.  Think there was a power_mode_switch app in an old version of the SDK that someone mentioned to me.  Is there a way to get a copy?

Thanks

Mike

EDIT:  I believe its the app referenced in application note AN12094, Power consumption and measurement of i.MXRT1050

Hi Michael

power_mode_switch.c can be found in software for AN12245

Power Consumption and Measurement of i.MXRT1060

https://www.nxp.com/webapp/Download?colCode=AN12245SW 

https://www.nxp.com/docs/en/application-note/AN12245.pdf 

In general changing the system clock and its dependencies at run time

possible using guidelines in sect.13.6.1.5.1 Clock Switcher i.MXRT1050 Reference Manual.

For example changing DDR frequency should be done from internal memory like OCRAM or FlexRAM.
