  • [ABANDONED] Cannot connect to target under VMware

    Hi,

    Our company has a VMware image of Linux (kubuntu 8.04) that other groups do some embedded ARM development with, using other JTAG devices. I'm trying to use our J-Link from within that VM to see if it will work for our current project.

    I have downloaded the Linux software package version 5.12f, TGZ archive and extracted to /usr/local/JLink_Linux_V512f_i386.
    I have installed the udev rules as described in the readme.
    I have an MSP-EXP432 Launchpad board connected to the VM just for something to play with until we get real hardware. The JTAG slide switch is set for external.
    I have the J-Link connected to the VM and the target via a 20-way to 10 way adapter.

    If I try to run JLinkExe and control the target it looks like it communicates with the J-Link OK but not the target:

    If I disconnect the J-Link from the VM and try the same parameters from J-Link Commander natively under Windows then it can connect and I can control the target OK. However, I'm not sure where to start trying to figure out why it won't work under the VM. Any suggestions?

    Thanks.

  • Hi,

    I assume this happens every time?
    Do I understand you correctly, that you are using a Windows Host with a Linux Guest(kubuntu 8.04) using VMware?
    Could you tell me the windows and VMware version you are using?
    Does this issue also occur if you connect the J-Link to the VM directly, without connecting it to the Windows Guest first?
    If you did this already, does this issue also occur if you connect the J-Link first to the Windows host, start J-Link commander, and then connect it to the VM?

    Would it be possible to provide us with the VM (full or stripped-down version, what ever you would prefer) for reproduction purposes?

    Best regards,
    Niklas
