ARM Cortex-R4F Re-entrant Example

Taylor Hillegeist

I was reading a post regarding re-entrant interrupts where you said:

Re: Is there ANY Cortex core that supports reentrant interrupts?


Hi Marcus, Cortex-R and Cortex-A processors does not have NVIC. Users (SoC designers) using these processors can use the Generic Interrupt Controller (GIC) or they could use their own interrupt controller. In terms of the processor itself, these processors don't have the priority level management as in Cortex-M processors so a programmer can create reentrant interrupt as in ARM7TDMI. regards, Joseph"

I have a TMS570LS3137 ARM Cortex-R4, I was curious if you could link me an example of how to implement a re-entrant interrupt on this?

Thanks,

    Hi Taylor,

    For Cortex-R, the code is dependent on the interrupt controller being used (not a part of the processor core).

    So different Cortex-R microcontroller products might need different arrangement.

    Currently I am on a business trip now, do you mind put your question on the ARM Connect Community forum so that other people can help out?

    Thanks
