Compiler/MSP432E401Y: Lwip with uartecho functions

Expert 1745 points

Part Number: MSP432E401Y

Tool/software: TI C/C++ Compiler

Hi,

I haven't seen any function in ethernet lwip example for sending the byte wise data through uart. Hence i try to use the  code in uartecho for uart configuration in enet_lwip program.

Then i am getting the linking errors. The errors are like as shown in below figure.

Thank you

Regards

kalyan.

    Hello,
    I will need to investigate the examples available and get back to you on 10/3. Please update if you have additional findings or progress.

    Hello Kalyan,

    It's not very clear what you are trying to achieve.

    Are you trying to send packets over UART to lwIP? What format are you planning to send the data to lwIP - HTTP, TCP or UDP?
    Are you trying to send lwIP packets to UART? What format are you planning to send the data to lwIP - HTTP, TCP or UDP? The "ethernet-based_io_control" example (in the folder "./examples/nortos/MSP_EXP432E401Y/lwip") does route text from a webpage (running over lwIP) to UART.

    Are you trying to do something else?

    Do you need to use lwIP? Another TCP/IP stack is also supported in SimpleLink MSP432E4 SDK which runs on RTOS. It is called NDK. There are some examples (like TCPecho and UDPecho), which can be modified to route data to UART instead of echoing to the source. These examples are in the folder "./examples/rtos/MSP_EXP432E401Y/ns".

    Thanks,

    Hello sai,
    Thank you for the reply. In my application, i want to realize serial to ethernet and ethernet to serial. Inorder to make changes in serial transmition settings like baud rate and protocol, i want to use web based control.
    That is why i try to use uartecho sample code in lwip.
    Please help me in realising that.

    Thank you

    Kalyan,
    Can you use the NDK or do you need lwIP?
