IWR1443BOOST: error upon calling CFAR HWA

jason Anderson

Part Number: IWR1443BOOST

Hi, after porting all necessary code from mmwave_demo regarding CFAR HWA into the high accuracy lab, i am getting an error i do not understand.

Error: HWA_configParamSet(12) returned -2801
{module#8}: "../data_path.c", line 1440: error {id:0x10000, args:[0x12498, 0x12498]}
xdc.runtime.Error.raise: terminating execution

reverse engineering the program leads to this line causing the error:

 (paramsetIdx>=ptrHWADriver->hwAttrs->numHwaParamSets)

What does this mean? this is all standard code from the mmwave_demo.

Please help me out, i need to get the CFAR HWA to work to find the closest peak possible.

Furthermore, where can i find the generated peaklist?

Hi Jason,

While adding the CFAR parameters, did you change the number of parameter sets used in the lab?

Thanks and Regards,
Michelle

No I did not, any other ideas?

Thanks,

Jason,

As you add more parameter sets, the number of parameter sets used increase. They need to consistent. Check .h file for the number of parameter sets and make sure the parameter set idx is valid.

Thanks and Regards,
Michelle

I copied all the functions from the mmwave demo, i only replaced the defined constant value names by the values. How can this be the case?

Jason,

I wouldn't know exactly what the issue is. Because the error shows it's related to number of HWA parameter sets, I asked about those settings. In your case, I suggest you to set break point and do a step-by-step debug.

Thanks and Regards,
Michelle

Hi, i am trying to get the HWA working with CFAR, i find the issue lies with the function

int32_t HWA_readCFARPeakCountReg(HWA_Handle handle, uint8_t *pbuf, uint8_t size)

as far as i can tell this is just a simple function to read a register containing the amount of peaks. however in the high accuracy demo this function does not exist. i want to know if you can provide me with an substitue function that will work in high accuracy lab. the main issue lies with:

 HWA_Driver              *ptrHWADriver = NULL;
    DSSHWACCRegs   *ctrlBaseAddr;

as i cannot find the declaration for these variables and their types.

cheers,

Jason,

Copying directly from mmw demo will not work. The datapath is different for the two demo/labs. The high accuracy lab only performs 1D FFT while mmw demo CFAR is based on 2D FFT matrix. You will have to develop your own function for the peak selection.

Thanks and Regards,

Michelle

I already have, but i figured the HWA also performs CFAR. so i want to try to set it to perform the CFAR. can i get any help with this?

cheers

Jason,

Sorry, we don't have a comparable function as HWA_readCFARPeakCountReg in high accuracy lab.

Thanks and Regards,
Michelle
