This examples includes: The lwIP 1.3.2 Altera TSE driver for lwIP 1.3.2. This uses the Altera altera_avalon_tse library unmodified. An example program. This has been tested with NIOS II IDE 8.1 SP0.01. Please report any changes or differences for later versions of the NIOS IDE. To create a NIOS II program utilizing lwIP 1.3.2 and the example program, you must create an Eclipse project. Use the "Hello World" template as it's the easiest to start with. Here are the complete steps: 1. Download lwIP 1.3.2: http://nongnu.askapache.com/lwip/lwip-1.3.2.zip 2. Unzip this into a folder on your PC 3. Use File -> New -> NIOS II C/C++ Application 4. Select "Hello World" from the template 5. Change the name to lwIP_NIOS_II_Example 6. Select the PTF file and CPU for your hardware configuration 7. Click Finish 8. Expand folder lwip_NIOS_II_Example and delete Hello_World.c 9. Use Import -> General - File System 10. Click "From Directory" Browse and find the lwip folder from step 2 11. Check the square box for this folder 12. Click "Into Folder" Browse 13. Select lwIP_NIOS_II_Example 14. Click Finish 15. Expand lwIP_NIOS_II_Example 16. Right click test and select Delete 17. Expand lwip/src/core 18. Right click ipv6 and select Delete 19. Use Import -> General - File System 20. Click "From Directory" Browse and find the folder that contains *this* download 21. Check the square box for this folder 22. Click "Into Folder" Browse 23. Select lwIP_NIOS_II_Example 24. Click Finish 25. Right-click project lwIP_NIOS_II_Example and select Properties 26. Select C/C++ Build 27. Select General 28. Add Include Path ${workspace_loc:/altera.components/Nios II Software Packages/altera_iniche/UCOSII/inc} 29. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include} 30. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include/ipv4} 31. Select Configuration Release from the pull-down 32. Select Preprocessor 33. Add Undefined Symbols: LWIP_NOASSERT 34. Add Undefined Symbols: LWIP_ERROR 35. Select General 36. Add Include Path ${workspace_loc:/altera.components/Nios II Software Packages/altera_iniche/UCOSII/inc} 37. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include} 38. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include/ipv4} 39. Select Configuration Debug from the pull-down 40. Click OK 41. Double click main.c 42. Edit alteraTseNetif.hwaddr[0-5] lines 78-83 with your board's MAC address Build and run the program. Something similar to the follow should appear if you have DHCP enabled on the connection: Running... INFO : TSE MAC 0 found at address 0x04001c00 INFO : PHY Marvell 88E1119 found at PHY address 0x01 of MAC Group[0] INFO : PHY[0.0] - Automatically mapped to tse_mac_device[0] INFO : PHY[0.0] - Restart Auto-Negotiation, checking PHY link... INFO : PHY[0.0] - Auto-Negotiation PASSED INFO : PHY[0.0] - Checking link... INFO : PHY[0.0] - Link established INFO : PHY[0.0] - Speed = 1000, Duplex = Full Waiting for link...OK Waiting for DHCP IP address...IP address: 192.168.123.136 Notes: The Marvel PHY 88E1119 is not supported in the default Altera library. You must have a System Clock Timer in your System Library. Change the #defines for USE_DHCP and BUILD_HTTPD as needed. If USE_DHCP is 0, STATIC_IP must be defined to a static IP address which is an IP address on your computer's subnet. lwIP configuration items in lwipopts.h have been set to be as close to as shipped as possible. They are not optimum for memory usage or bandwidth. The intent of this example is to provide a working TSE driver and lwIP example program. The project should build and run if the instructions above are followed correctly. Good luck with lwIP and your Altera TSE based project. Bill
