Hi team,
Here's an issue from the customer may need your help:
The code modification is based on SRR demo and only USRR mode is enabled. In the Mss_SRR_CLI.c file, the customer added a new CLI command and its callback function:
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 reconfigured
dynChirpCfg[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;
}
The CLI commands advFrameCfg and sensorStart perform well during debug, but after entering the custom reconfiguration command, the following error occurs:

Could you help check it? Thanks.
