Hi experts

I just have finished transporting data between DSP and PRU by regarding internal memory as shared memory .

And I'm facing a problem：

My project require hard real time,when PRU finish writing data ,I can easily post a interruption to DSP, and DSP will read data from the specified memory address in time. But I don't find any introduction on how to post a interruption to PRU.

Any help will be appreciated.

Hi,

We have a Wiki for PRU-ICSS with interrupt examples, can you take a look: processors.wiki.ti.com/.../PRU_Training:_Hands-on_Labs

Thanks for your help ,Eric

In this training, communication between ARM and PRU base on RPmessage.

If it is possible to do that between DSP and PRU? And I need DSP post message to PRU.
