Hi


Just asking the ethernet cable setup, did you connect the ethernet cable to your laptop or it is through a router?

For static IP you would need to connect the board ethernet directly to your laptop ehternet port. After that in the laptop ethernet setting set the ip address to ip mentioned in the board.

Besides that you could remain your current setup and change the IP from static to DHCP.

Hi,

I connect the board directly to my laptop and use static IP. Can't ping the board or ping from the board. I tried to use packet sender to send UDP data to the board to see if the core can receive anything but it didn't trigger the receive routine in mSGDMA. How should I process?

By the way reduce the SSS_TX_BUF_SIZE help me with the NetBuf_Get problem. Apparently the MTU size is less than the SST_TX_BUF + header, so it failed. Reduce the buffer size help the Tx trigger, but it still have timeout problem that Ping still failed.
