Problems with Cyclone IV and DP83848C

--- Quote Start ---

From the calloc error message, it looks like you don't have enough memory for the embedded system. You can try and reduce the number of buffers in ipport.h, increase the size of your onchip_mem, or connect the Nios CPU to an external RAM (if you have one on board).

Thanks a lot. I followed your advise and the result seems to be better.

But when i ping the board with cmd or telnet, there seems to be no connection. The following shows the Nios II Console content:
