Nano connection to ICBOOST

Other Hardware 3rd Party Boards

I hope you can help me.

I am trying to connect my Arduino Nano to a Texas Instruments ICBOOST (which is connected to an mmwave radar IWR6843AOPEVM) - I have it connected via the GND, TX and RX pins (power comes from the USB to the Nano and AC power to the ICBOOST) but I cannot get the Nano to receive any data from the ICBOOST? COMs and baud rates and wire connections have all been confirmed as good.

Do you have any ideas that might help me or is there anything obviously wrong with my setup as detailed above?

Any help you could offer would be greatly appreciated!

No ideas because you didn't show your code and schematic.

As for the code:

I'm thinking it's the wiring. I have the TX/RX from the ICBOOST connected to the Nano's D2 & D3 because from what I understand with the Nano is the RX/TX pins are used by the USB chip for uploading sketches etc so connecting the ICBOOST to those pins would cause confliction? I have not connected the 5v pins as I have before fried a Nano from using more than one power source....

How was this accomplished? It is starting to appear they are not correct. Also using pins 0 and 1 (Tx and Rx) is normally not allowed unless you know for sure what you are doing. The best solution is to use another processor with an additional hardware serial port.

Hint RESET does not send signals. Post an annotated schematic showing what you have. If this picture does not match your board that is an even bettr reason to include a achematic.

Thank you - that's very helpful! I think you're right, I'm going to set up again but use the Mega.
