F28M36P63C2: F28M3x ethernet demo

Part Number: F28M36P63C2
Other Parts Discussed in Thread: CONTROLSUITE

Hello,

I test F28M36 ControlSUITE ethernet uip demo. The desription is:

//*****************************************************************************
//! \addtogroup master_example_list
//! <h1>Ethernet GPIO control using uIP stack (enet_uip)</h1>
//!
//! This example application demonstrates controlling a GPIO pin using ethernet
//! communication. It makes use of the uIP TCP/IP stack.
//! A basic web site is served over the Ethernet port. The web site displays
//! a few lines of text, a Toggle LED button, an input to select an LED (6 or 7)
//! and a get status button. The user specifies which LED needs to be toggled
//! and presses the Toggle button. The user gets the status of the LED(ON or
//! OFF), by pressing the Get status button.

But when I try to access the web 169.254.254.169, there is no response. And when I ping this IP address, there is error too.

Could you help with it?

And is there any PC host software could control the GPIO through the ethernet? Or any detailed guidance about it?

Thanks

    Hi,

    Hope you have done the settings as specified below in the example code :

    In the "Internet Protocol(TCP/IP)
    //! properties" window select "Use the following IP address" and enter the
    //! following:
    //! IP address: "169.254.42.86"
    //! Subnet mask: "255.255.0.0"

    If you have done that, please check in the Receive statistics if it shows any increment as you do the ping/access. 

    Regards,

    Hi Sudharsanan,

    Yes, I changed my IP address and subnet mask according to the guidance.

    But when I try to access the server "69.254.254.169", there is no response. And when I ping this IP address, there is error too.

    BTW, this project (Ethernet GPIO control using uIP stack (enet_uip)) use the Cortex.M.LM3S9B96 as default device.

    And my ControlSUITE version is:

    v3.4.9 - March 28, 2018
FCL SFRA Library and Example Files v1.00.00.00
    BOOSTXL_POSMGR v1.01.00.00

    Hello,

    Could anyone give me some idea about how to use the F28M36 ethernet uip demo. Thanks a lot.

    Hi,

    The usage is as per the usage instructions in the example. Since you said you tried all the steps as told, I would next keep a breakpoint in EthernetIntHandler() and check if any ping from windows PC results in a Rx interrupt or not. can you try that out and post your observation? It will help to isolate if any packets are received on the setup or not.
