AWR2944EVM: mmWave Start Sensor issue

Deepan V

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

Tool/software:

I tried importing the AWR294x "High End Corner Radar" CCS example code from the resource explorer. Based on the instructions from the User guide,

1) The AWR2944 device is flashed using the pyscript "uart_uniflash.py" , the required python libraries are also imported.

2) I am able to compile (with no errors), run and load the program to the target (both mss and dss) using CCS (mcuplus SDK for AWR2944). The helloworld example project works fine and able to get the output in the terminal (COM Port is functional)

Issue :
Post connecting the targets (Cortex R5_0 and C66x_DSP), I am encountering an mmWaveStart_Sensor issue (refer to the attached image)

Adding the Status log from the console (also highlighted in the image below):

Please help me in handling this.

Hi Deepan,

Can you cross verify the calibration paramter in mss_main.c?

Just check if it is same or not.

Hi Animesh,

Thank you for your response, the 'reportEn' field was missing in the default code. I tried adding it, didn't help either.

Hi Deepan,

What is the error log you are getting? Is it same or different from above?

Hi Deepan,

Can you flash the prebuilt binaries in your board and check if it is working or not?

Hi Animesh,

These are the pre-built libraries that were flashed,
--------------
python uart_uniflash.py -p COM8 --cfg=sbl_prebuilt\awr294x-evm\default_sbl_null.cfg
--------------
And also the 'awr2944_corner_radar.appimage' flashed to the EVM(without using the CCS) works fine, I am able to see the results in the Automotive Visualizer.
But the 'Build and Run' through CCS for High-End Corner Radar (project imported from TIREX) is supposedly not working (mmWaveStart_Sensor issue mentioned earlier). I require help in get it working using CCS.

Deepan

Hi Deepan,

Did you made any modification in the code? As it is working in our side.

According to your issue,

The issue is BSS calibration fail. Inside that

Rx gain calibration is missing.

Hi Animesh,

There is no modification done in the code, I ran it by just importing it from TiREX.
I rechecked the portions that you have mentioned above, they remain unaltered.

Could you please mention the procedure you have followed to load the program using CCS? So that we could replicate it.

Deepan

Hi Deepan,

First thing you can do is instead of giving this command python uart_uniflash.py -p COM8 --cfg=sbl_prebuilt\awr294x-evm\default_sbl_null.cfg

try using default.cfg.

default.cfg

First you need to load the project on CCS. then Build MSS project, DSS project will automatically get built. then load the respective binaries on to respective core. then run R5 core and then C66 core.

Hi Animesh,

The CCS debug issue have been fixed, also is there is any user guide for ethernet data receiption for high end corner radar

Hi Deepan,

Currently we don't have any such user guide as you are asking for. If you have any doubt on that topic, you can raise a new E2E thread.
