    Hi LiangXiao,

    How did you suply the mcu? Did you connect 12v to VS pin or did you only supply the mcu with the vddp?

    Kind Regards

    Hi Muratzi,

    the TLE98xx needs to be powered over the VS pin.
    We can not guarantee the functionality when it is externally supplied over VDDP.
    Did you try the connect the VS Pin for flashing over SWD?

    Best,
    Fiz

    Hi Fiz,

    I connected VS pin for flashing. I have some doubts about my j link segger. Can i use tle987x evalboard to swd debug another mcu which is on tle987x evalboard? I mean debuging one tle987x evalboard
    which is powered 12v with one tle987x evalboard as the j link.

    Hi Murat,

    What problem do you have with your j-Link?
    Are you using the TLE9879 Evalkit or the TLE987x Evalboard?

    The XMC4200 used on the Evalkit uses a 3.3V logic.
    To flash the TLE9879 several level-shifter are used to lift the signals to 5V.
    The level-shifter on the evalkit are supplied by VDDP, coming from the TLE9879.
    So if you would not connect VS at the 1. board to only use the debugger, the levelshifter would not be supplied.
    You could try to connect VDDP of the 1. board to an external 5V supply.
    Please keep in mind this is not an intended usage of the kits and we can not guarantee for this to work.

    Hello Fiz,

    Because i have some doubts about my hardware design, i wanted to be sure about j link. Because of this i wanted to debug tle987x eval board thanks to another tle987x in order to be just sure that i
    have some problems with my hardware design. I debuged tle987x eval board with another tle987x board that is used as just j link and it worked with my style connection(it is a bit different from yours).
    Now i will use the same approach with the new designed hardware mcu tle9871. I think with the new design, i will be able to debug and load program to my pcb that will has tle9871.

    kind regards
    Murat

    Hi fiz,

    I have a board that is attached. This board have tle9871 mcu and i want to debug it with tle987x eval board. But it does not work. I plug in the sw cables directly without any resistance. Do you think that it will work?

    Hi Murat,

    if you connect all signals and the power correctly, this should work.
    For the Evalboard we are using a daughter board with a spring socket to evaluate different variants.
    Do you have one of those?
