DM9000 Ethernet device driver for stand-alone lwip

Hello, 

 

Some months ago I started to write a device driver for the DM9000 Ethernet MAC/PHY from Davicom for the stand-alone lwip from Microtronix. Now I have more time for this project. 

 

That’s what I did until now: 

1. Component “altera_avalon_dm9000” for using it in the SOPC Builder, 16 Bit mode 

2. “dm9000if.c” for “\lwip4hal\netif\” instead of “lan91c111if.c” 

3. Demo program “lwip_rx_test” 

 

It’s the first time that I’m developing software/hardware for a network application. So it’s hard to bring that stuff to work. Currently it is possible to “ping” the board and to send some UDP packets from a PC to the board. But after sending some UDPs or pings the board breaks the communication. And I don’t know why. Is it a problem with the DM9000 driver, with lwip or the demo program? 

 

Is there someone who would like to use the DM9000 and has some knowledge to bring this project further? 

 

 

Bye,
