AWR2243BOOST: MIMO calibration does not work

Hi Max,

Let me check this at our end first. I will get back to you by EOD on this.

Thank you. I am waiting.

Hi Max,

Thanks for your patience. The TX enable table that you have shared in the above snippets there the 31 is not your antenna counts. If you check in the script the Tx Enable Table indicates the number of chirp configurations vs total Tx. So, in the 31*12 number 12 is your total Tx antenna count over the 31 possible chirp configurations. There's nothing wrong with the scripts.

The antenna calibration script stops working at this point.

This is where it throws an error and the calibration matrix is ​​not created. This is why I created the post.

Hi Max,

Please make sure that you are following the steps properly which are mentioned in section 8.3.2 in the following document -

mmwave_studio_02_01_01_00/docs/mmwave_studio_cascade_user_guide.pdf

Also, can you confirm if you are using the standard scripts given in the studio or you have made any modifications for your application?

HI Shruti

All steps were performed according to the instructions.

I use standard scripts, I attached them to this post. Please look above. I tried to provide the maximum information. The problem is not solved and I asked you for help.

Hi Max,

Can you recheck the device variant whether it is ES1.0 or ES1.1. Also, if you have any other device can you try to perform the same experiment there as well and see if you are facing the similar issue.

Shruti

Hi Shruti,

I add photos

I don't have another device.

Hi Max,

I want the device variant details whether it is ES1.0 or ES1.1

Shruti

where is this marking located? (ES1.0 or ES1.1)

Hi Max,

Please refer to the following thread -

ES1.1

Hi Max, 

Are you using all 31 chirps in your application, if not can you remove those chirp configurations and try the same experiment again. There's nothing wrong with the script it is just some indexing or assignment issue. The  TxChannelEnable(iconfig) can only store a single value, but from the 13th index (when numchirpconfig is 13) it is being assigned to an array.
