  • [SOLVED] 2 pin cjtag cc1310 J-Flash 6.62d

    Hi!

    I was trying to connect to my cc1310 device via J-Flash, using the cJtag interface.
    My observation was the following:

    Having the following setting in J-Flash


    I am able to connect to my cc1310 device, as long as all 4 Jtag pins are connected.

    We have our own 2*4 connector with this pinout


    Once I disconnect TDI and TDO from the device (by actually cutting them on the PCB
    then the J-Flash can not connect anymore.



    According to the following page, the cjtag should in fact work with only 2 pins: segger.com/products/debug-prob…tion/#cjtag-compatibility


    My questions are:

    1. should 2pin cjtag in fact work via J-Flash 6.62d?
    2. Should I be able to debug via Ozone (I would like to do it via CCS 10.0 as well, but I just ask the folks on the TI forum)


    As a sidenote, the device I was trying to connect was already flashed previously (4 pins connected) with a software image. I tried to check if the cJtag could be disabled by the ccfg aka. Customer Configuration of the cc1310 device, but I do not think so.

    The final goal is to use this adapter in our new board design: segger.com/products/debug-prob…ers/6-pin-needle-adapter/

    Any help would be appreciated.
    Thanks!
  • Hi,
    Thank you for your inquiry.

    You are using a fairly old version of the J-Flash software.
    Could you please give the latest version a try?

    It is available as part of the J-Link Software and Documentation Pack here:
    segger.com/downloads/jlink#J-L…twareAndDocumentationPack

    Best regards,
    Fabian

  • Hi Fabian,

    thanks for your reply.
    In fact I can verify, that the cjtag does work in a 2 pin configuration with the cc1310 even with the J-Flash 6.62d.

    As most often it was a user error on my side, after proper setup of the HW it works flawlessly.

    Cheers!
