Periodic timer Interrupt Priority configuration

Dev15 — Tue, 13 Feb 2024 06:12:39 GMT

Hello Team,

We have configured periodic timer interrupt (PIT) instance 0 with 4 channels in S32 SDK configuration tool which are listed below

channel 0 (ISR 1)

channel 1 (ISR 2)

channel 2 (ISR 3)

channel 3 (ISR 4)

I'm trying to prioritize the ISR for above channels. Please help me in setting the priority for each of this channels

Thank you

Sorry for the late reply. Please post question in the S32K community next time. So that the internal system can assign your question to the engineer.

These four channel share the same Interrupt Priority, so you are not able to set different priorities for channels of an LPIT instance.

Best Regards,
Robin

@Robin_Shen ,

Thank you for your response.

I'm trying to create task schedulers based on priority levels say 1ms, 5ms, 10ms tasks.

Please let me know if any other sources available in s32k apart from PIT
