MSP432P401R: Designing Hardware Based off Launchpad

Part Number: MSP432P401R

Hi,

If I'm designing hardware based off of the MSP432P401R Launchpad, what pages of the schematic are essential to support USB programming? In general, I just need the ability to program the MSP432 -- all other connections to the GPIO's can be made at my team's own discretion.

My thinking is that sheets 1 (MSP), 4 (XDS110 debug probe), and 6 (misc. interfaces) are essential. Some aspects of page 2 might also be helpful (RST button). Page 3 seems like it's just headers (although we might choose to eventually include this page as part of the design to aid in hardware debug).

My biggest question mark is sheet 5. Do I need anything on this sheet to successfully create an interface with the MSP432 so that it can be programmed via USB? My understanding of EnergyTrace is very superficial, so can anyone help explain what the things on this schematic sheet are for? Thanks!

Michael

    Michael,

    Also refer to page 3's "XDS110-ET <<--->> LaunchPad" block on the lower right, showing the power, reset, JTAG and UART connections made from the XDS110 debug probe side of the LaunchPad to the MCU side.

    EnergyTrace is a real-time power consumption reading from the MSP432 MCU, and can be viewed using the EnergyTrace GUI. More information here. Simply ignore this page of the schematic if you will not be need this.

    BR,
