[SOLVED] J-Links debug probe and pinout

  • [SOLVED] J-Links debug probe and pinout

    Hello,

    I currently use a for my project Renesas E1 and E20 probe to debug a soft running on RX631.
    I would like to use a Jlink one for testing purpose (try RTT and percepio in streaming mode).

    My question is about the JTAG pinout. Our board has a 10 pin connector as follow:

    1 EMLE TDI 6
    2 TCK RST 7
    3 TRST GND 8
    4 TDO VCC 9
    5 TMS VCC 10

    The segger JLink probes use 20 or 14 pin connector.
    Does a custom adapter for 10 pin JTAG will work with Jlink?

  • Hi,


    We sell this adapter for RX:
    segger.com/jlink-adapters.html#RX
    segger.com/jlink-rx-adapter.html

    The adapter 's connector is not compatible with your Layout.
    Does a custom adapter for 10 pin JTAG will work with Jlink?

    Yes, you will need to connect the pins manually.
    Regarding the layout, please refer to segger.com/cms/admin/uploads/u…dapter_Rev5_Schematic.pdf

    Best regards,
    Niklas
