RTOS/IWR1642: How to change rx channel in iwr1642 sorfware?

Hi Wesley,

I was using mmwave_sdk_01_01_00_02. I have changed with mmwave_01_02_00_05 when you say it. But the result have not change. When I have sent channelCfg 3 1 0 configuration to device isn't working.

I have looked mmwave_sdk_user_guide.pdf but i couldn't find the solution to the problem.

Thank

Naz

Hi Wesley,

I have tried and it has happened. Which channels are open to this configuration? Are RX1,RX2 and TX1 channels open or any other channels?

I have my own design. My design have RX1,RX2 and TX1 channels. Is it suitable for this configuration?

Regards,

Naz

Hi Wesley,

This problem hasn't been solved. I have selected 2RX and 1TX channels because my own design place is limited. Therefore i have selected RX1,RX2 and TX1 channels.

I want this configuration:

RX1 channel is enabled.

RX2 channel is enabled.

RX3 channel is disabled.

RX4 channel is disabled.

TX1 channel is enabled.

TX2 channal is disabled.

I have sent channelCfg 3 1 0 , channelCfg 3 2 0 , channelCfg 12 1 0 and channelCfg 12 2 0 configurations separately with the my own design GUI. But ı couldnt it.

channelCfg 3 1 0 --> Which channels are open in this configuration?Are RX1,RX2 and TX1 channels enabled? I am wondering how the configuration is done.Can you give me any information for this configuration?

We will use "Human and Object Detection Radar For Indoor and Outdoor Applications".  Hence 4RX and 2TX channels are not necessery for my application area. 2RX and 1TX are enough for my design. I want to use only range calculation. 

Hi Naz,

Yes, channelCfg 3 1 0 is TX1, RX1, RX2 enable.
Please find more details in C:\ti\mmwave_sdk_01_02_00_05\docs\ mmwave_sdk_user_guide.pdf
Thanks.

Thanks Wesley.

I will try and back you.

Naz.

Hi  Wesley,

I have tried this channel 3 1 0 cofiguration. And i saw this error in the following ficture:

Sensor is not starting. Can you give me any information in this error?

Thanks

Naz

Hi Naz,

I have try SDK1.1 demo, and I have listed the setting I used for 1TX2RX case test. Could you please double check if you can use the online GUI to set the IWR1642 work in 1TX2RX mode?

Thanks.

Wesley,

I have sent this configuration in the online and offline GUI:

I have have this error both of gui configurations. Sensor is not working. I have saw the following error:

Hi Naz,

Are you using IWR1642EVM, could you please check the items listed below:

• Did you flash the correct BIN file to device?
• Could you please replace another 5V2A or 5V3A power supply to try it again?
• Did you try other EVM and other default configuration?
• What's the 1443 version? ES2.0?

Regards,

Wesley

Wesley,

I think i gave wrong information on my project. My project like in this following picture:

So i have only 2RX and 1 TX antenna channels.

I have wrote .bin file (in the SDK 01.02.00.05 version) in the QSPI flash using uniflash program. And I have loaded source code(in the SDK 01.02.00.05) in the iwr1642 using CCS. Then I have tried to run sensor using mmWave Visualizer online and offline version,but sensor didnt work. 

When i sent to channelcfg 3 1 0 (for 2RX and 1TX channel)and sensor want to start i have see this error: 

xWR16xx MMW Demo 01.02.00.05

******************************************

mmwDemo:/>Debug: Init Calibration Status = 0x11e

MSS Exception: mss/mss_main.c, line 2148.

I have checked AR_RS232TX,AR_RS232TX and AR_MSS_LOGGER connection but i couldnt see any mistake. 

Could you  suggest any idea for me?

Thanks,

Best Regards,

Naz

Hi Naz,

This board is nice.
I recommend you use IWR1642EVM to test 1TX2RX's configuration and BIN file. After the configuration is correct, you can try it on your own board.

Regards,
Wesley

Hi Wesley,
I used IWR1642EVM to test 1TX2RX's configuration and bin file. IWR1642EVM board worked in this configuration. But my board didnt work the same configuration.


Is there anything else I need to do?

Regards,
Naz

Hi Joe,

I have preproduction(XI1642QGABL)  iwr1642 which both iwr1642evm and my board. I have tried SDK 01.01.00.02 and  SDK 01.02.00.05. IWR1642EVM have worked for 1TX2RX. But my board didnt work. I have saw the same error.

I dont understand where i am making mistakes.

Is there anything else I need to do?

Thanks

Regards

Naz

Hi,

I have checked 3V3,1V2,1V3 and 1V8 voltages. All of them is correct.

I have checked the other voltages:

-AR_1V4_SYNTH and AR_1V4_APLL voltages is equal to ~1.4V.

-AR_VBGAP and AR_VOUT_PA voltages is equal to ~0.9V.

I have checked the hardware checklist but i didnt see any mistakes.

I will ask the design engineer, the calibration may be affected by the number of connected Tx and Rx ports. -->  Did you ask this question?

I  have saw ICD document, how does should i BSS configuration change? 

Thanks.

Regards.
