TMS570LS1224: Change system clock during runtime

Konstanty Kuczynski1

Tool/software:

Hi,

is it possible to change the system clock during runtime? In our application, we want to start the system on a lower clock frequency and adjust it to 160MHz after the startup routine. Is this even possible? If so, what steps are necessary?

Kind Regards,

Konstanty

Hi Konstanty,

I don't have any direct code to provide, however we can change the clock frequency based on our requirements.

Refer below thread once:

(+) CCS/TMS570LS3137: How to Dynamic change PLL output frequency - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

And also refer below steps in the TRM:

Based on this data i hope you can write a code to change the core clock frequency. Just try from your end and if you face any issue then i will do further assistance.
