RTOS/AM5718: Examples of AM5718 PRU and DSP interaction

Hendrix

Part Number: AM5718

Tool/software: TI-RTOS

I'm looking for some good example code to load, run, and pass data from the AM5718's PRU to the C66x core. This needs to show how to interrupt the C66x from the PRU.

The RTOS team have been notified. They will respond here.

Hello,

Is the ARM running TI-RTOS or Linux?

The ARM core is running Linux, but is not involved in this part of the processing. The C66x is running without any RTOS, just using CSL.

We have a PRUSS example that demonstrates event and interrupt handling between the PRU and DSP. It will need to be built into a CCS project by running the following commands in terminal:

cd C:\ti\pdk_am57xx_1_0_12\packages
pdksetupenv.bat
pdkProjectCreate.bat AM571x all little pruss all dsp

Some documentation for reference:
