Hello,
I am very new in TI-RTOS. I want to add a CAN interrupt handler to my testing system.
I started with an empty example from "Resource Explorer" of Code Composer Studio 6.1.1.00022.
I initialized CAN device. When I send a CAN message from my PC to TM4C based target device, Interrupt from CAN is activated.
I can know this because there is an error saying that system cannot find ISR. This is the error message on a console when I send a CAN message to the target.
[CORTEX_M4_0] Starting the example
System provider is set to SysMin. Halt the target to view any SysMin contents in ROV.

Terminating execution...
This is the setting for CAN ISR in empty.cfg.
/* ================ Driver configuration ================ */
var TIRTOS = xdc.useModule('ti.tirtos.TIRTOS');
TIRTOS.useGPIO = true;
var hwi0Params = new Hwi.Params();
hwi0Params.instance.name = "hwi0";
Program.global.hwi0 = Hwi.create(40, "&testInterruptHandler", hwi0Params);
And This is the ISR named testInterruptHandler.
Void testInterruptHandler(UArg arg0)
{
System_printf("Testing Interrupt Handler\n");
/* SysMin will only print to the console when you call flush or exit */
System_flush();
}
Can you give me an advise to solve this problem?
Regards,
Young
