    using LWIP with CMSIS RTOS and custom threads

    Dear all,
    I have a XMC4800 Relax Development Kit and try to setup a simple Ethernet communication.
    Following the documentation of "ETH_LWIP - Usage" I'm able to configure and setup the Ethernet communication with a RTOS.
    After calling osKernelStart() I'm able to ping the device.
    Now, I would add two additional thread to my application. One should handle the TCP communication and the other control additional IO's.

    Unfortunately, as soon as I define an thread and use osThreadCreate(osThread(thread1), NULL) the device doesn't respond to a ping.
    My thread is working.
    Does any one know, how to add additional threads to the CMSIS RTOS when using LWIP?
    Or does some were exist an example using lwIP wit cmsis rtos and custom threads?

    Thanks for any hint!

    Hi,

    Be sure to have configured correctly the "Number of concurrent running user threads" and "Number of threads with user-provided stack size"
