我在使用AWR1843 EVM过程中，开启了Can口中断接收功，有时通信频繁会造成板卡意外死机，仿真中发现Can口中断影响了chirp的正常计数，造成frame启动时计数不为0。有没有设置中断优先级的资料，使chirp计数优先级更高？
你好，
我看了一下代码，目前canfd和chirp/frame event中断都是设置的优先级都是一样的。相关代码如下：
canfd的中断注册代码：
canfd.c
HwiP_Params_init(&hwiParams);
hwiParams.name = "CANFD_0";
hwiParams.arg = (uintptr_t)ptrCanFdMCB;
ptrCanFdMCB->hwiHandle0 = HwiP_create(ptrCanFdMCB->hwCfg.interruptNum0, CANFD_MCANInt0Isr, &hwiParams);
chirp中断：
dss_main.c
/* Register interrupts. */
SOC_SysIntListenerCfg listenerCfg;
/* Register Chirp Available Listener */
memset((void*) &listenerCfg, 0, sizeof(SOC_SysIntListenerCfg));
listenerCfg.systemInterrupt = SOC_XWR18XX_DSS_INTC_EVENT_CHIRP_AVAIL;
listenerCfg.listenerFxn = MRR_DSS_chirpIntCallback;
listenerCfg.arg = 0;
gMrrDSSMCB.chirpIntHandle = SOC_registerSysIntListener(gMrrDSSMCB.socHandle, &listenerCfg, &errCode);
soc_xwr18xx_dss.c
void SOC_deviceInit (SOC_DriverMCB* ptrSOCDriverMCB, int32_t* errCode){...
/*********************************************************************************** * Frame Start System Interrupt ***********************************************************************************/ HwiP_Params_init(&hwiParams); hwiParams.name = "FrameStartISR"; hwiParams.arg = (uintptr_t)&ptrSOCDriverMCB->sysIntTable[sysIntIndex]; ptrSOCDriverMCB->sysIntTable[sysIntIndex].intNum = SOC_XWR18XX_DSS_INTC_EVENT_FRAME_START; ptrSOCDriverMCB->sysIntTable[sysIntIndex].hwiHandle = HwiP_create(ptrSOCDriverMCB->sysIntTable[sysIntIndex].intNum, SOC_SystemISR, &hwiParams); HwiP_disableInterrupt (ptrSOCDriverMCB->sysIntTable[sysIntIndex].intNum); sysIntIndex++;
/*********************************************************************************** * Chirp System Interrupt ***********************************************************************************/ HwiP_Params_init(&hwiParams); hwiParams.name = "ChirpAvailableISR"; hwiParams.arg = (uintptr_t)&ptrSOCDriverMCB->sysIntTable[sysIntIndex]; ptrSOCDriverMCB->sysIntTable[sysIntIndex].intNum = SOC_XWR18XX_DSS_INTC_EVENT_CHIRP_AVAIL; ptrSOCDriverMCB->sysIntTable[sysIntIndex].hwiHandle = HwiP_create(ptrSOCDriverMCB->sysIntTable[sysIntIndex].intNum, SOC_SystemISR, &hwiParams); HwiP_disableInterrupt (ptrSOCDriverMCB->sysIntTable[sysIntIndex].intNum); sysIntIndex++;
...}
HwiP_tirtos.c
void HwiP_Params_init(HwiP_Params *params){ params->name = NULL; params->arg = 0; params->priority = ~0; params->enableInt = TRUE;#ifdef SUBSYS_MSS params->type = HwiP_Type_IRQ;#endif}
