TMS570LC4357: lwIP Demo: Pre-built Version 00.03.00 Not Working

Part Number: TMS570LC4357


I am working on Hercules TMS570LC43x Development Kit. Trying to get the lwIP demo working.

I loaded the pre-built out file to the board and executed. (File location: HALCoGen EMAC Driver with lwIP Demonstration\lwIP\TMS570LC43x\Demo Executable\Build-TMS570LC4357ZWT.out)

The result is as follows:

Texas Instruments
Big Endian device
Initializing ethernet (DHCP)
        DEBUG - Getting PHY ID....SUCCESS
        DEBUG - Getting PHY Alive Status...SUCCESS
        DEBUG - Getting PHY Link Status...SUCCESS
        DEBUG - Setting up Link...SUCCESS


Why is this problem happening?

Isn't it supposed to be working or am I doing something wrong?



  • I've fixed the issue, let me explain if anyone needs help in the future:

    The demo application has a defined length delay for acquiring an IP address from the DHCP server.

    In our network, it took more time to establish a connection and acquire an IP address, so I've increased the delay where the DHCP communication is established. That fixed the issue for me.

    Hope that helps,

    I am forwarding to our software team so they may follow up.
