Hi experts;

(1)I have Refered this similar thread AWR1243:

I use nonos mmm demo, what should i write in pHandler??

RL_P_EVENT_HANDLER g_RlInterruptFunc;
char gDeviceIndex = 0;
rlInt32_t app_RegisterInterruptHandler(rlUInt8_t deviceIndex, RL_P_EVENT_HANDLER pHandler, void* pValue)
{
g_RlInterruptFunc = pHandler;
return 0
}
/* GPIO interrupt handler for HotINT*/
void gpioIsr(gioPORT_t *port, uint32 bit)
{
g_RlInterruptFunc(0, &gDeviceIndex);
}

Hi Dan,

This is correct implementation to handle the interrupt from AWR device, where HostIRQ line is connected to one of your GPIO on Host Processor.

Another point to note that whenever you are expecting Async-event in your flow then rlNonOsMainLoopTask and rlAppSleep as implemented in one of DFP example

C:\ti\mmwave_dfp_02_02_03_01\ti\example\mmWaveLink_SingleChip_NonOS_Example\mmw_example_nonos.c

retVal = rlDevicePowerOn(deviceMap, clientCtx);
while (mmwl_bInitComp == 0U)
{ /* waiting for powerup Async-event */
rlNonOsMainLoopTask();
rlAppSleep(5);
timeOutCnt++;
if (timeOutCnt > MMWL_API_INIT_TIMEOUT)
{
retVal = RL_RET_CODE_RESP_TIMEOUT;
break;
}
}

Regards,

Jitendra
