AWR2944EVM: Init Calibration Status = 0xffe Error

Ganesan Thiagarajan53

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944,

I am using AWR2944 EVM and SDK 4.4 along with the cloud agent. I have modified the default profile with my custom changes. When I issue the "sensorStart" command, I am getting an Init Calibration Status = 0xffe Error.

Can you please let me know what I am doing wrong the profile. I am attaching the log here.

Hi,

If the user selected invalid parameters in the user generated configuration file or the sliders in the CONFIGURE tab generate an invalid configuration, then the mmWave sensor device reports back an error of -1.

I can see the idle time being selected as 2 us but for AWR2944 minimum value should be 2.5 us.

The configuration file you are using can contain more faults like this. Please refer to the SDK user guide and visualizer user guide to input all correct allowed values.

Thanks,

Pradipta.

Hi Pradipta:

Thanks for your reply. Can you please point me to the document/URL which lists the minimum/maximum parameters limit such as minimum idle time for AWR2944? Is there any interactive tool which I can use to choose the chirp and profile configs for the application we have.

Regards

Ganesan

Hi,

Please use the ICD for information on all the API's to radar front end communication. It can be found in the below path form the SDK folder.

ti\mmwave_mcuplus_sdk_04_04_01_02\mmwave_dfp_02_04_09_01\docs

Also, you can use the mmWave Studio for RF control and data evaluation and also the ramp time generator tab in the Studio can be used to tune your profile parameters.

MMWAVE-STUDIO IDE, configuration, compiler or debugger | TI.com

Thanks,

Pradipta.

Hi:

Thank you for sending the information about ICD. It looks like mmWaveStudio needs additional DAV data capture card for proper experimenting with the frames and chirps config. I also found one App Report "SWRA553A" useful, which talks about the various capabilities with respect to chirp configuration. Also, Chapter 11 on ICD gives specific limits on xWR294x devices. This is exactly I was looking for. Thanks for your inputs.

I will modify my profile config file according to this and try on the AWR2944EVM. I request to keep this ticket open for another few days, till I check the modified config file on the hardware.

Best regards

Ganesan

Hi:

I modified one of the example profile config files for TDM mode. Unfortunately, the default demo code does not accept the configuration. I am getting an exception "mmwDemo:/>sensorStart <LF> Exception: ./mss/mmw_cli.c, line 301."

I am enclosing the modified config file. Can you please help me in correcting the same?

I am trying a advFrameConfig with 3 sub-frames each with different Slopes and chirp numbers as listed in the Table below.

These sets of 3 subframes are repeated every 50 msec.

Adv. Frame	Chirp No.	Ramp BW (MHz)	Ramp Slope (MHz/usec)	ADC window time (usec)	over head time (usec)	Total Chirp Duration (usec)	Chirp Duty Cycle (%)	Max IF (MHz)
SubFrame #1 of 3	1-255	360	45	8.00	6	14	57.14286	15.00
SubFrame #2 of 3	1-510	180	22.5	8.00	6	14	57.14286	15.00
SubFrame #3 of 3	1-1023	90	4.5	20.00	6	26	76.92308	6.00
