Part Number: SK-TDA4VM

Hi,

I am trying to run lwip example on MCU2_1 / MCU1_0 in SK-TDA4VM board, but in none of the cores the example is working,

The code is not able to get the IP from the DHCP server, I confirmed that my router is configured as DHCP server.

Below is the screenshot of the issue,

Please support me to resolve this issue.

Hi,

Can you please confirm router is connected to CPSW2G or CPSW9G?
From log it seems that CPSW2G on MCU domain is enabled, please connect router to CPSW2G port and check once.

Best Regards,
Sudheer

Hi,

In the SK-TDA4VM board there is only one ethernet port and is connected to CPSW-2G, one thing I found out in my debugging is , when i run the sciserver , the ethernet gets disconnected immediately that is what is causing the issue.

Hi,

The lwip example for CPSW2G has Sciserver integrated into it, no need to run separately.
If your are loading via CCS, after completion of .jel file loading before starting MCU1_0 core (MCUR5F_0) reset the core and load lwip example application.

If you loading Sciserver application separately then lwip example will not work.
