AWR1243BOOST: Cant set chirp config through mmavelink_example

Hi,

I am working on awr1243 with devpack, and try to run mmwavelink_example on it.

Q1: I found this mistake:

Calling rlSetChirpConfig with
ProfileId[0]
Start Idx[0]
End Idx[0]
*** Failed - Parameters are mismatched GetChirpConfig compare to rlSetChirpConfig ***
*** getChirpCfgArgs[1].profileId = 0 while setChirpCfgArgs[0].profileId = 0 ***
*** getChirpCfgArgs[1].freqSlopeVar = 0 while setChirpCfgArgs[0].freqSlopeVar = 0 ***
*** getChirpCfgArgs[1].txEnable = 2 while setChirpCfgArgs[0].txEnable = 1 ***
*** getChirpCfgArgs[1].startFreqVar = 0 while setChirpCfgArgs[0].startFreqVar = 0 ***
*** getChirpCfgArgs[1].idleTimeVar = 0 while setChirpCfgArgs[0].idleTimeVar = 0 ***
*** getChirpCfgArgs[1].adcStartTimeVar = 0 while setChirpCfgArgs[0].adcStartTimeVar = 0 ***
Chirp Configuration success for deviceMap 1

In config file, I set txEnable to 1 but it seems like it does not set to radar somehow, Could you explain this to me?

Q2: Later I also want to run 2*4 MIMO on 1243, in which case I need to set two different chrip files. But in config file it does not have a block like "manage chip" in radar studio. How could I do "manage chip" in mmwavelink_example?

Hi,

Have you made any changes to the configuration?

The example has been tested and should be running out of the box

Thank you
Cesar

I do not think so though, I will try to re-install it again.

How about Q2, Can we configure mutiple TX at the same time as MIMO ?

Hi,

You can define as many chirp as you prefer.

For e.g. Below configuration would configure 2 chirps in MIMO. You can modify it for your specific configuration
=================================================

int MMWL_chirpConfig(unsigned char deviceMap)
{
int retVal = RL_RET_CODE_OK;
rlChirpCfg_t setChirpCfgArgs[2] = {0};

setChirpCfgArgs[0].chirpStartIdx = 0;
setChirpCfgArgs[0].chirpEndIdx = 0;
setChirpCfgArgs[0].profileId = 0;
setChirpCfgArgs[0].txEnable = 1;

setChirpCfgArgs[1].chirpStartIdx = 1;
setChirpCfgArgs[1].chirpEndIdx = 1;
setChirpCfgArgs[1].profileId = 0;
setChirpCfgArgs[1].txEnable = 2;

/* With this API we can configure max 512 chirp in one call */
retVal = rlSetChirpConfig(deviceMap, 2U, &setChirpCfgArgs[0]);

return retVal;
}

int MMWL_frameConfig(unsigned char deviceMap)
{
int retVal = RL_RET_CODE_OK;
rlFrameCfg_t frameCfgArgs = { 0 };

frameCfgArgs.chirpStartIdx = 0;
frameCfgArgs.chirpEndIdx = 1;
frameCfgArgs.framePeriodicity = 20000000;
frameCfgArgs.numAdcSamples = 512;
frameCfgArgs.numFrames = 8;
frameCfgArgs.numLoops = 32;
frameCfgArgs.triggerSelect = 1;

retVal = rlSetFrameConfig(deviceMap, &frameCfgArgs);
return retVal;
}
=================================================

Kaushal
