  • [ABANDONED] One j-Trace not connecting to CC2640R2F, while two others connect fine

    Hi,

    We have three Segger j-Trace units. Two of them connect and debug perfectly with the CC2640R2F (although unfortunately only in full JTAG, not cJTAG, but that's another story...).

    We've tried swapping cables, target boards, everything and it's definitely the j-Trace. We get the error message "Failed to get CPU status after 4 retries. Retry?" and the following log:

    Can anyone provide a thought why it might not be able to connect? As I say, two other j-Trace units from the same era (all say Version 3.2 on the sticker) work perfectly.

    For Segger's reference, our serial numbers are in my profile. The one ending 269 fails to connect.

    Thanks,

  • Hello Richard,

    Thank you for your inquiry.

    Sounds like the J-Trace CM is not working properly. To make sure could you provide a J-Link commander output of a connection sequence with the affected J-Trace?
    More information how to can be found here: wiki.segger.com/J-Link_cannot_connect_to_the_CPU

    Could you also provide the J-Link log file from the affected J-Trace?
    More information how to can be found here: wiki.segger.com/Enable_J-Link_log_file

    Best regards,
    Nino
