Hi


I am Jingyang and will be helping out on this case.

When you mention you increased the mSGDMA to 2K are you referring to the buffer size?


When it is on listening, that means you are able to connect to it by ssh.

Try using another device (using Putty or Telnet) and connect to 192.168.1.234 with port 80.

You should be able to receive some logs from the board.


Regards

Jingyang, Teh

    Hi Jingyang, thank you for your support!

    I did try with putty and it said connection time out. I started debug and tried to ping from the board and it failed. The NetBuf_Get method failed. I noticed the Tx led is always on. So I think there maybe some error with the buffer address pointer of the mSGDMAs or TSE.
