IWR6843ISK: Compatibility of IWR6843ISK Rev D with MMWAVEICBOOST — 60-Pin Connector Alignment and J4 Connection

Tool/software:

Hello TI Team,

I have been working with the IWR6843ISK Rev B board along with the MMWAVEICBOOST board successfully using the 60-pin connector interface. In this setup, I configure the radar over UART using RS232_RX and RS232_TX from the ICBOOST board, and control reset using nRST. I retrieve radar data via the MSSLOGGER UART pin.

Recently, I purchased a new IWR6843ISK board, and the one I received is Rev D. However, I noticed that the two 60-pin connectors on the Rev D board are not in parallel, unlike the Rev B board. As a result, I'm unable to plug it directly into the MMWAVEICBOOST board in the same way.

I have the following questions:

1. What is the recommended method to connect the IWR6843ISK Rev D board to the MMWAVEICBOOST board, given the connector layout difference?

2. Is it possible to use only the J4 60-pin connector of the MMWAVEICBOOST board with the IWR6843ISK Rev D for my use case (UART configuration via RS232_RX/TX, nRST control, and data via MSSLOGGER)?

3. Are there any specific hardware jumper settings or firmware changes required to support this configuration with Rev D?

My application does not currently use the XDS110 on the MMWAVEICBOOST. I only use the mentioned UARTs and reset line to configure and communicate with the radar.

Any clarification on supporting Rev D with existing MMWAVEICBOOST hardware would be very helpful. Additionally, could you please provide the schematic and datasheet for the IWR6843ISK Rev D board?

Thanks and regards,
