IMXRT595-EVK DSP and CM33 Peripheral Access Isolation

[wx1]

Hi NXP community, I'm working with the MIMXRT595-EVK​ board (Cortex-M33 + Fusion F1 DSP dual-core system) and have a question about peripheral access between the two cores.
I'm developing a dual-core application where the CM33 acts as the main processor and the DSP handles real-time signal processing. After processing data, I'd like the DSP to directly control some peripherals (like GPIO/LEDs) to indicate status without involving the CM33 for every operation.

Wish it helps you.
If you still have question about it, please kindly let me know.

Thank you, the peripheral access address of both cores is the same, right?
I'm using zephyr and rt595, but I find that there is no device tree for peripherals in DSP, Is it my code version issue?

Hi @wx1 ,

Thanks for your updated information.

A1: Yes, it is right that  the peripheral access address of both cores is the same. Please refer to RT500RM chapter2 Memory Maps

A2: I do not think  it is  your code version issue,  Currently, Zephyr's support for the MIMXRT595 is mainly focused on the Cortex-M33 core.

please create a new case for future issues. we will do our best to support you.
