AM2732: DSS configuration for AWR2243 cascading

Amine LTAIEF

Part Number: AM2732
Other Parts Discussed in Thread: TDA2, AWR2243

Hello,

I started working on this board by reusing the firmware from the AM2723evm board and updating some firmware related to the TIDA020047, such as the CLI for MSS parts. However, when it comes to the DSS part, do I need to update anything related to the processing part?

I updated the antenna geometry file to include the cascading configuration on the board and made some changes to the defines related to Rx and Tx numbers. However, I have not been successful in obtaining any results from the DSS. Do I need to consider other factors?

here is my configuration for chirps,

Thank you for your advice

Regards

Thanks for the post - perhaps you left off the configuration attachment or table in your post.

I can point you to this TI Design, where the AWR2243 was used in cascade configuration with the TDA2 (https://www.ti.com/product/TDA2LF) , and the chirp configs are on page 11. https://www.ti.com/lit/ug/tiduen5a/tiduen5a.pdf
