MCU-PLUS-SDK-AM263X: Generating interrupts from CMPSS?

Hi Daniel,

You can do it in a similar way, route the signal to Input X-Bar and use the 10.2.1 Vectored Interrupt Manager (VIM) to register the interrupt.

Can you give me more details?  Using Sysconfig?

From the TRM: It is important to note that the function selected on the GPIO multiplexer does not affect the INPUTXBAR. The INPUTXBAR simply connects the signal on the input buffer to the selected destination.

So you can directly route the CMPSS trip from OUTPUTXBAR to INPUTXBAR by choosing the muxed GPIO with the XBAR, which can be found in the Control Card User Guide.

After that you can use the DPL, HwiP to register an interrupt an example for which can be found in examples/kernel/dpl/dpl_demo.

All the available interrupt numbers can be found in source/drivers/hw_include/am263px/cslr_intr_r5fss0_core0.h

Are you familiar with Sysconfig?  Your answers don't seem to address that.  I wasn't able to get it working with just Output XBAR and INPUT XBAR.

and calling interrupt number like this:
HwiP_Params_init(&hwiParams);
hwiParams.intNum = CSLR_R5FSS0_CORE0_INTR_GPIO_INTRXBAR_OUT_14;
hwiParams.callback = &cmpss0IntrISR;

Are you saying I need to physically connect a wire between two GPIOs?
