[FAQ] TDA4VM: Routing interrupts via the interrupt router

TDA4VM: Interrupt Router configuration

Hello Team,

The TDA4x support interrupt router configuration through TI-SCI RM interfaces.

I came across an IntRtr configuration @ti-processor-sdk-rtos-j721e-evm-07_03_00_07/gateway-demos/mcuss_demos/mcal_config/IntRtr_Cfg/output/generated/soc/j721e/mcu1_0/IntRtr_Cfg.h and also @ ti-processor-sdk-rtos-j721e-evm-07_03_00_07/mcusw/mcal_drv/mcal/examples_config/IntRtr_Cfg/soc/j721e/mcu1_0/IntRtr_Cfg.h.

So how is there any possibility to configure the interrupts through EB tresos tool apart from SCI interfaces ?

    Hi Namashivayam,

    I believe you need to use the SciClient APIs to configure the interrupt routers and this can not be done via configurator. I will still double check this. 

    The MCAL examples in the SDK also do that. You can see the can_app example as well - see CanApp_InterruptConfig() in sdk7_3/ti-processor-sdk-rtos-j721e-evm-07_03_00_07/mcusw/mcal_drv/mcal/examples/Can/soc/j721e/mcu1_0/CanApp_Startup.c

    Regards,

    Karan
