在进入调试模式之后，更改了profile.cfg文件中的起始频率，使其满足IWR1843的起始频率，运行GUI，但是依然报错：

在mmWave_link.c中定位到这个错误的解释是：
/****************************************************************************************

freqLimit.freqLimitLow = ptrMMWaveMCB->openCfg.freqLimitLow;
freqLimit.freqLimitHigh = ptrMMWaveMCB->openCfg.freqLimitHigh;
retVal = rlRfSetCalMonFreqLimitConfig(RL_DEVICE_MAP_INTERNAL_BSS, &freqLimit);
if (retVal != RL_RET_CODE_OK)
{
/* Error: Frequency Limit Calibration */
*errCode = MMWave_encodeError (MMWave_ErrorLevel_ERROR, MMWAVE_ECALCFG, retVal);
retVal = MINUS_ONE;
goto exit;
}
