IWR6843ISK: IWR6843: Problems with openSensor and Out-of-Box HWA demo with mmWave-SDK 3.4.0.3

Hi,

I have a problem with running the out of box HWA demo on the IWR6843-ISK module.

I'm using the following configuration (from mmWaveDemoVisualizer 3.4.0, note that the HWA demo needs the platform to be set to xWR64xx which is kind of strange):

% ***************************************************************

After sending the config to the mmw-device using the visualizer I get the following error:

Error: mmWave Open failed [Error code: -3119 Subsystem: 119]

The error code means:

/**
* @brief Error Code: mmWave link BSS calibration configuration failed
*/
#define MMWAVE_ECALCFG (MMWAVE_ERRNO_BASE-19)
rlRfSetCalMonFreqLimitConfig(), returns 119

Further debugging reveals that the problem arises when the rlRfSetCalMonFreqLimitConfig function in mmwave_link.c is called:

int32_t MMWave_openLink()

...

    freqLimit.freqLimitLow  = ptrMMWaveMCB->openCfg.freqLimitLow;
    freqLimit.freqLimitHigh = ptrMMWaveMCB->openCfg.freqLimitHigh;
    retVal = rlRfSetCalMonFreqLimitConfig(RL_DEVICE_MAP_INTERNAL_BSS, &freqLimit);

In SDK 3.3 the frequency limits were both set to zero in main.c and in the new SDK they are set to 600 and 640 respectivley in the OOB-demo.

Setting the limits to zero as a workaround does not help, the same error still arises.

Can you please advise me how to solve the issue?
