  • [SOLVED] SEGGER J-Link Plus connect to Raspberry Pi 4 USB port not working

    Hello Everyone!

    My set-up is I connect the SEGGER J-Link plus in raspberry pi 4B 4GB USB Port.

    I downloaded the latest software JLink_Linux_V788c_arm.
    I follow the procedure in README.txt
    --> sudo cp 99-jlink.rules /etc/udev/rules.d/
    --> sudo reboot

    Then I do this command in the [b]JLink_Linux_V788c_arm folder:[/b]
    --> sudo ./JLinkExe
    to run the jlinkExe but the output is
    --> bash: ./JLinkExe: No such file or directory

    Anybody can help me with this? Please!!!!

    I'm very new in using SEGGER Jlink in raspberry Pi
    I already run the SEGGER Jlink in windows and it's working.

    I also check the lsusb command and the SEGGER J-Link is detected and connected.
    The problem I think is running the JlinkExe.

    Is there any complete procedure in installing the J-Link in raspberry Pi 4?
  • You should check 2 things:

    1)
    Make sure that you are using the 32-bit version of Raspberry Pi OS if you are using the "Linux_arm" version of J-Link.
    If you are using Raspberry Pi OS 64-bit, you need to use the "Linux_arm64" version of J-Link.

    2)
    The file attributes may probably got lost during extraction.
    Did you check if "JLinkExe" has the executable attribute?
    ls -l should indicate the "x" attribute for JLinkExe.

    We recommend to use the DEB installer over the tgz because it takes care of the rules file and other pitfalls.

    Edit:
    There is no need to run JLinkExe with superuser permissions (sudo).
    This is the whole idea behind having the rules file: No sudo needed afterwards...
