TIDA-010022: Connecting IWR1642BOOST to LAUNCHXL-CC1352R1 (sensor node) without hardware modifications

Part Number: TIDA-010022
Other Parts Discussed in Thread: LAUNCHXL-CC1352R1, IWR1642BOOST, TIDEP-01000, , IWR6843, IWR1642

Please, is there a way to connect the IWR1642BOOST to LAUNCHXL-CC1352R1 (sensor node) without any hardware modifications on the IWR1642BOOST?

Thank you.

    Some HW modification will be required.

    If you want to mate the two boards, all the hardware modifications listed in the design guide are required.

    If you are ok with the boards being separated, you can reduce the modifications to one. You would power each board separately, and configure the IWR board using the GUI from TIDEP-01000 (you can get the IWR config parameters from TIDA-010022). Once the IWR board is up and running, you would still need to wire the AR_MSS_LOGGER pin to the UART RX pin on the CC1352. That last step will still require one HW modification, check the IWR1642BOOST schematics. You would also need to disable the code in the CC1352 that attempts to configure the IWR.

    Btw, we will be updating TIDA-010022 to support IWR6843 in the next couple of weeks.

    Thanks Gus, that was most helpful. But if I am not removing R128 and R129, which disconnects AR_RS232TX and AR_RS232RX from the Jtag debugger, How are we supposed to get those signals into the CC1352 board? Would I need a cable connected to the 60-pin HD connector, single out those 2 wires, cut them, and solder into individual pins to connect on the CC1253 lunchpad appropriate pins?

    Thank you.

    AR_RS232RX and AR_RS232TX would go to the debugger so you can use the GUI to configure the IWR board rather than have the CC1352 do it.  It's a trade-off for making the "least number of hardware modifications".  :-)  If you want the CC1352 to configure the IWR board, then, yes, you have to make those modifications.

    Btw, jumper wires are great for connecting Launchpads and Boosterpacks together. Here is an example from Digikey.

    Thank You, I finally understood your recommendations. One last question: If I remove resistors R128, R129, and R136, which route the AR_RS232TX, AR_RS232RX and AR_MSS_LOGGER, and place resistors R169, R166 and R26, i would lose the XDS110 debugger connection with the PC via the mini-USB port, correct? 

    Would it be possible to "share" the connections, by only adding resistors R169, R166 and R26 (and not removing R128, R129 and R136) so that I don't lose debugging through the PC? Are there any shortcircuit/interference problems in doing this?

    If this approach is possible, then I could have the CC1352 configuring the IWR1642, and thus run the TIDA-010022 setup by wiring the UARTS (side-by-side, not mounted on the j5/j6 launchpad connectors)

    Thank you!
