S32K3XX STM timer causing DMA error

Chase1234 — Tue, 15 Aug 2023 16:54:46 GMT

I am using an S32K. I have an STM timer that is being initialized in my code that is causing a 37 vector to be activated. This vector is tied to the DMA Channel 17. I was wondering what interactions the STM and the DMA have that could be causing this vector to be active while the DMA is not turned on?

Hi @Chase1234,

what is the package's name you are using?

Did you check the interrupt handler function installed for STM interrupt and DMA interrupt?

Could you send me your configuration files (.arxml files)?

Best regards,

Dan
