Part Number: MSP432E401Y

Tool/software: TI-RTOS

Hi,

I am running 'tcpecho' program in mps432e401y launchpad.

Though echo is happening, it is not lasting. After some time it is not echoing the data.Can any tell me why it is happening?.

(I have connected launchpad to PC)

Thank you

Regards

Kalyan.

    Kaylan,
    I can try to recreate the issue on my side. Can you quantify the amount of time the communication lasts? Is the PC continuously transmitting or periodically(how often)?

    Thanks,
    Chris

    Hi Chris,
    I am using real term for send and receiving the data through UART0. I am sending one character at a time. After sending 32 characters, echoing is not happening, however network connection is there and the respective LED's are blinking on the launchpad.

    Thank you
    Regards
    Kalyan.

    Can you confirm which program that you are running?  I have the PC connected to the virtual com port through the xds110 of the launchpad and the ethernet connected to a switch.   I can see the service status in Tera Term and the eco in the command line (python script).

    After a while I do get this error:

    Hi Chris,
    Thank you for the reply.
    I am also using the virtual com port xds110 and for sending and receiving i am using real term.
    I have connected launchpad to my PC(both USB & RJ45) directly.

    Thank you
    Regards

    Hello,
    When connecting RJ45 directly to PC can you still see the network added?

    Are the following conditions met:

    The device must be connected to a network with a DHCP server to run this example successfully.

    The example starts the network stack. When the stack receives an IP address from the DHCP server, the IP address is written to the console.

    Run the tcpSendReceive python script that is shipped with your SDK.

    dev.ti.com/.../

    When the echo stops are any errors provided?

    Chris
