AM2434: IPC Notify instead of SGI

Mari Tsunoda
Expert 5726 points
Part Number: AM2434


Tool/software:

Hi Team,

Is there no software interrupt for the AM2434?  I checked the interrupt map in the TRM for the R5F0-0 core but could not find. 

Can IPC Notify be used similarly to a software interrupt?

Best regards,

Mari

    Hi Mari, if you can give us more details about your use case it would be great. I am guessing you need to notify an "event" between cores, if so, IPC could be used. However, please keep in mind IPC's main purpose is for communication between cores by sending messages to synchronize tasks or share data and there is a latency associated.

    While looking for this question, I found that indeed we don't have a replacement for PDK's SWI API's in MCU+SDK AM243x MCU+ SDK: OSAL Migration Guide. However, I found few other ways this could be achieved in FreeRTOS, few options below

    Hardware Interrupts, RTOS Timers, Task Notifications, Direct Task Switching, Deferred Interrupt Handling

    As mentioned before, let us know more details about the use-case, so I can pull the right experts to help us with ideas or point us to examples

    Thank you,

    Paula
