  • [SOLVED] Is J-Link PRO supporting multiple GDB Servers connected via Ethernet (i.MX6Q)

    Dear Community,

    Please find the reproduction steps (i.MX6Q):

    Power cycle the board
    Stop at U-Boot prompt


    ./JLinkGDBServerExe -select IP=192.168.2.72 -device MCIMX6Q6 -endian little -if JTAG -speed auto -noir -noLocalhostOnly

    (gdb) target remote localhost:2331
    (gdb) hb *0x17800000
    (gdb) c


    Boot Linux


    GDB halts on the address:
    Breakpoint 1, 0x17800000 in ?? ()


    At this point I do want to start the other instance of GDB Server (for Core #1):

    ./JLinkGDBServerExe -select IP=192.168.2.72 -device MCIMX6Q6 -endian little -if JTAG -speed auto -noir -noLocalhostOnly -scriptfile ~/work/J-Link-PRO/MCIMX6-core-1.JLinkScript -port 2334 -swoport 2335 -telnetport 2336 -logtofile -log ~/aaa.txt


    Unfortunately, it is not possible (after following the above steps) to start
    multiple GDB server instances to use Ethernet as the connection medium.


    However, I can start multiple instances with '-select USB' switch passed (instead
    of -select IP=).


    Is the connection to multiple GDB Servers supported with ETH (IP=192.168.2.X) or
    is it only working via USB (J-Link PRO has both USB and ETH ports)?


    Please find attached aaa.txt log file.



    Note:
    The MCIMX6-core-1.JLinkScript is from
    linode.boundarydevices.com/jlink/MCIMX6-core-1.JLinkScript


    With the above setup (debug steps) the guidelines/scripts from
    wiki.segger.com/I.MX6DQ
    are not working.


    Thanks in advance for your help.

  • We are currently working on a new multi-processing concept / solution which is expected to be completed in Q1/2020.
    This will then allow multiple connections via IP (if all come from the same host PC)
    For now, you are limited to 1 connection via IP.
