    • Wanted: Compatibility matrix between SW4STM32 and JTAG programmers

    Posted by mnewman on 2017-03-15 16:42
    Hi all, I'm targeting an STM32F4 and plan to develop on Windows with the latest SW4STM32. I'm trying to get a feel for JTAG programming options. Does some list of compatible programmers exist? Bonus points if it explains what capabilities are added/missing for various combinations. Thanks!

    Hi,
    The first columns explain the signals functionalities.
    SW4STM32 will only use JTAG pins when in JTAG mode or SWD pins when in SWD mode.
    All the STM32 nucleo and disco have only SWD connection.
    The advantage of SWD is pin reduction compares to JTAG.
    The only drawback i see is if using several boards (mcus) in daisy chain. Daisy chain access is not possible in SWD.
