IWR6843AOPEVM: IWR6843AOPEVM

HI, Ankur:

Did you run AOP as a standalone module and power is provided from USB cable?  Or you are connecting AOP on top of mmwaveICBooster?

The AOP standalone mode does not have enough power to support 3 TX beamforming.  

Best,

Zigang

Hi zigang,

Based on suggestion, I connected AOP on mmwaveICbooster. But still sensor is not able to start. Below is the error from terminal:

Any other suggestion for beamforming to work? Also, are there any specific switch settings in booster for AOP to get work with booster?

Please suggest workaround to get beamforming working.

Thank you.

HI, Ankur:

The switch setting on AOP will be different, if you connect it with ICBOOSTER board.  Please check the figure 4-15 at the following user guide:

https://www.ti.com/lit/ug/swru546d/swru546d.pdf?ts=1615229018963&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FIWR6843AOPEVM

Hi Zigang,

I changed the switch settings as shown in fig 4-15 and mounted AOP on booster. But still sensor is not able to start and error in the terminal is same. Is there a possibility of mismatch between out of box demo binary file and cfg file(attached previously) for beamforming?

Please suggest for another workaround.

Thank you!

Ankur

Please make sure that the configuration without TX beamforming works first.  And please send me a picture of your setup. 

Best,

Zigang

Hi zigang,

Setup is working without Tx Beamforming with AOP mounted on booster. I can get point cloud data. Please see images below:

But with beamforming enabled, the error is same. Please see below:

Any other suggestions for beamforming to work?

Thank you.

HI, Ankur:

Which demo binary are you using for this experiment?  Is the same binary you used for both AOP one TX and AOP 3 TX beamforming? Are the two configurations also provided from the TI demo?

Best,

Zigang

Hi Zigang,

For binary I am using out of demo binary file xwr64xxAOP_mmw_demo.bin. Yes same binary file is used for both AOP one Tx and AOP 3 Tx.

Cfg files are created. I already attached cfg file for AOP 3 Tx in first message. Please refer attachment in first message.

Regards,

Ankur

HI, Ankur:

I tried this binary and it does not work for me either.   You can try the xwr68xx_mmw_demo.bin in the SDK OOB demo.   Although it is not designed for AOP, but it supports 3 TX beamforming.    IF it apply to you as well, then at least it mean your board is working fine with TX beamforming.  

Best,

Zigang

HI, Ankur:

By the way,  your script does not match with xwr68xx_mmw_demo binary.  You need to add following CLI comment before sending sensorStart

bpmCfg -1 0 0 0

Best,

Zigang

Hi Zigang,

Would you like to provide binary and cfg file which is working for you for Tx beamforming?

Thank you.

Regards,

Ankur
