  • GDBServer and TCP/IP Server

    Hi,

    how is to tool supposed to be used? If start GDBServer for ARM and
    afterwards the TCP/IP Server on the same host, I can't connect to
    port 19020. gdb always reports:

  • Hi Markus,

    you can not run both servers on the same machine if they both connect to the same J-Link.
    All you need here is the GDBServer.
    GDB can connect to to the gdbserver on localhost, default port is 2331.

    I know and I can connect to GDBServer directly. However, I'd like to use the TCP/IP Server and can't connect to it...

  • If I get the point you are trying to connect the GDB with the J-Link TCP/IP Server.
    THIS IS NOT POSSIBLE!

    The GDB does not understand the J-Link TCP/IP Protocol used by the J-Link TCP/IP Server. Therefore the GDBServer is used, which uses the GDB Protocol.
    For example, the J-Link TCP/IP Protocol is supported by the IAR Embedded Workbench for ARM.


    The GDBServer is intended to be used with GDB only.
    The J-Link TCP/IP Server can be used with any debugger that supports the J-Link TCP/IP Protocol but will definitive not work with GDB!

    GDB supports only GDB protocol!

    If I misunderstand what you are trying to do please do some further explanation for us to understand what you are trying to do.
