  • [ABANDONED] STM32 - Connecting to CPU via Connect under reset failed

    Hi,

    I currently have an issue with my JLink Base. I am using IAR and every time I go to download the following JLink Driver error appears : STM32 - Connecting to CPU via Connect under reset failed.

    I have used my colleagues J-Link and I see no issues, download completes successfully which indicates no hardware issues with the target board.

    I have updated and reverted the firmware on the JLink with no success.

    Connecting via commander tool gives me the same error.

    Any ideas?

    Glen

  • Hello Glen,

    Thank you for your inquiry.
    Such an issue is not known to us.
    What is the S/N of your J-Link and what is the S/N of the J-Link of your colleague?
    How does your J-Link Commander output look like when you try to connect? Could you post a screenshot? wiki.segger.com/J-Link_cannot_…nection_is_unsuccessful_2
    Are you using an eval board or custom hardware?

    Best regards,
    Nino
