  • GDB Server Hang on OSX when using -select

    Hi,

    I have two JLinks and I was hoping to use -select between the two based on serial number when they are both plugged in.

    The server fails when I use the option and connects properly when I don't.

    I'm running OSX 10.9.2. Other version numbers are included in the output below.

    Thanks for reading,

    Kenny

  • Hi,

    Is your J-Link configured properly to be identified by the serial number?
    You are using a *very* old hardware version of the J-Link which has not been shipped with this setting from factory.

    Could you please do me a favor and start J-Link Commander and type:
    J-Link>rconf

    and post the output?

  • Hi Alex,

    I happened to be on Windows when I issued rconf below. I assume this doesn't matter.

    I have been considering upgrading that hardware but it's actually not all that clear to me what benefits a new device has to offer. It'll probably cost me $300-400USD to upgrade which is fine if there is reasonable value.

    Sorry: I tried to improve the formatting below and failed.

    Thanks,

    Kenny

  • Hi,

    Sorry: I tried to improve the formatting below and failed.

    I fixed this for you...

    The configuration looks fine so far.
    Unfortunately, the J-Link model you are using is out of support, so I cannot assign a high priority to this.
    Anyhow, I have added this to the list of investigations to be done within the next weeks in order to check if we can reproduce this problem.
