RTOS/MSP432P4111: Dynamically changing priority of Clock Module SWI

Julian Kolodko

Part Number: MSP432P4111

Tool/software: TI-RTOS

G'Day all,

I understand that the clock module in SYSBIOS runs as a SWI and the priority of that SWI is configured either using Clock.swiPriority in the .cfg file or via the GUI.

Is there any way to change the Clock SWI priority dynamically using the Swi_setPri() function?

Cheers

Hello Julian,

Reading the TI-RTOS Kernel Runtime APIs and Configuration, I did not find any reference to configuring Clock.swiPriority dynamically (during runtime instance creation) using an API or modifying an element in a structure.

I will try to find out more on this.

Thanks,

Sai

In theory using Swi_getPri/Swi_setPri should work. The issue is finding the Swi_Handle. We don't expose a way to get the Clock's Swi_Handle. It's inside an internal Clock structure (which we don't recommend directly accessing).

Thank you Sai,

Given that what I'm trying to do is unsupported, I'll restructure a bit (maybe using a dedicated timer) to achieve what I need.

Cheers
