AWR1642: 添加自定义CLI命令以实现动态chirp配置，在调用该CLI命令时报错

您好，我在SRR demo的基础上进行代码修改，我只启用了USRR模式
在mss_srr_cli.c文件中，我添加了新的CLI命令及其回调函数

cliCfg.tableEntry[4].cmd= "reconfiguration";cliCfg.tableEntry[4].helpString= "Idle time";cliCfg.tableEntry[4].cmdHandlerFxn  = SRR_MSS_CLIChirpReconfiguration;

static int32_t SRR_MSS_CLIChirpReconfiguration(int32_t argc, char* argv[])
{int32_t retVal;rlDynChirpCfg_t dynChirpCfg[1U];unsigned int cnt;dynChirpCfg[0].chirpRowSelect=0x30;//Enables only chirp row 3 to be reconfigureddynChirpCfg[0].chirpSegSel=0;dynChirpCfg[0].programMode=0;for(cnt=0;cnt<2;cnt++){dynChirpCfg[0].chirpRow[cnt].chirpNR3=(rlUInt32_t)atoi(argv[0]);}rlDynChirpCfg_t *dynChirpData[1]=&dynChirpCfg[0];retVal=rlSetDynChirpCfg(RL_DEVICE_MAP_INTERNAL_BSS,4U,&dynChirpData[0]);/* Check for mmWaveLink API call status */if (retVal != RL_RET_CODE_OK){System_printf("Error: Unable to configure the dynamic chirp [Error %d]\n",retVal);return -1;}rlDynChirpEnCfg_t dynChirpEnCfg = {0};retVal = rlSetDynChirpEn(RL_DEVICE_MAP_INTERNAL_BSS, &dynChirpEnCfg);if(retVal != RL_RET_CODE_OK){/* Error: Link reported an issue. */System_printf("Error: rlSetDynChirpEn retVal=%d\n", retVal);return -1;}return 0;
}

在调试时，CLI命令advFrameCfg和sensorStart执行得很好，但输入自定义的reconfiguration命令后出现以下错误：

请问这个问题该如何解决？

Cherry Zhou：

您好，收到您的问题了，我们需要请求下国外工程师的帮助。

Cherry Zhou：

您好，

这个错误看起来与毫米波链路无关。

可能是与 ARM Memory Protection Unit相关。

调用"rlSetDynChirpCfg（)"之后是否会发生此错误？

你好,修改我的CLI函数后该问题不再出现
