AWR2243: mmwave link error 282 while sending chan cfg

Part Number: AWR2243

Hi team,

Good day! We need your help for our customer's concern below. 

Here it is.

We recently purchased AWR2243 ES1.1 and cascaded two of them in a custom PCB. We are facing the error -282, while  sending command rlSetChannelConfig.


We were going through imaging radar application note "swra574b", it is mentioning the use of AWR2243. We were able to use the XAWR2243P in the same hardware design and an application based on mmwavelink to capture data. Based on the radar interface control document, the error = "282 Device variant does not allow cascading but API is issued to enable cascading mode". We are now suspecting if something should be configured differently since we are using AWR2243 ES1.1 and not AWR2243P ES1.1. We kindly request you to advise us on how to proceed.
Thank you so much for your guidance. 
Best regards,
Jonathan
