RTOS/AM5728: Shared interrupts

Hello，

When I configure the communication between the ARM and the DSP on AM5728, I use MessageQ . This way is a polling mode waiting for the message from the other one.

Now I want to use the shared interrupt to communicate,but I cann't find the shared interrupt in "AM572x Technical Reference Manual".

I know a shared interrupt register like SYSCFG_CHIPSIP on OMAP138.

Is there a similar one on AM5728?

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

Now after I read the manal about AM5728,I find ,OCMC_RAM that is the shared memorry between ARM and DSP. Can DSP response the interrupt about OCMC_RAM from ARM ?Can you give me some help about OCMC_RAM and the example about it?

Are you using Linux or bare metal RTOS?

Hello,

AM5728 uses mailbox for interrupts, please see Chapter 19 of the Technical Reference Manual for details on the mailbox module.

The IPC Notify driver uses mailboxes to send notifications to remote processors, you may also refer to the cdocs located at ipc\docs\cdoc\ti\sdo\ipc\family\vayu to see how it's been implemented.

If you have any further questions please let me know.

My board is AM5728. CCS RTOS

Now I want to generate a interrupt from ARM and the DSP can respond the interrupt .I find that the DSP can respond the GPIO interrupt from the ARM.

I also find that the OCMC_RAM is the shared memory which can generate a interrupt? Can I use this interrupt to achieve my purpose?Is there a example about the OCM?
