TIDA-00807: How to program the on-board MSP430

Part Number: TIDA-00807
Other Parts Discussed in Thread: MSP430FR5728, MSP-FET


I am working on fault indicator. The reference design mentions about 2-wire JTAG (Spy-Bi-Wire) interface. I want to know if it is same as serial-wire debug interface?  Actually, I have 4-wire JTAG emulator can I use this  emulator for 2-wire JTAG interface?

Thanks and regards


  • Hello Deepak,

    Yes, this design features the 2-wire SBW interface as shown in the design's schematic (actually a very valuable resource that basically shows all the hardware connections). You can program the MSP430FR5728 using the J1 header on the board. If you have our MSP-FET debugger, it supports both 2-wire SBW and 4-wire JTAG. If your debugger isn't manufactured by TI or one of our partners, then I would highly recommend that you purchase one.

    If you have more questions about the debug interface, please read through our MSP Debuggers User's Guide and MSP430 Hardware Tools User's Guide.
