How can I use cs8900a in NIOSII?

[Altera_Forum]

I fount that there is no HAL and UCOSII folder in the path of \altera\kits\nios2\components\altera_avalon_cs8900.Then how can i use cs8900a in NIOSII? 

If I have to write the HAL drive ,is there existing example that i can copy or imitate?  thanks to all! http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif

To make it work you would:  1) Copy the LAN91C111 component folder and rename as necessary to make the SOPC builder see it as a new CS8900 component.  2) Modify the LAN91C111 driver to work with the CS8900.  3) Figure out which lines from your new CS8900 component go to which pins on the daughtercard.  Not a simple task...  Edit: by the way, cross-posting a topic to different forums is frowned upon.

But there are many differences between cs8900 and lan91c11,so it is hard to say whether i can work it out.  Is there verilog or vhdl code of cs8900 so i can build a new component in SOPCbuilder?

Copy the LAN91C111 folder to a new directory and look at the files inside with a text editor, specifically the PTF file. Rename everything that says LAN91C111 to CS8900, save, and reopen SOPC builder. You should have a CS8900 component now.   From there you&#39;ll need to modify the PTF file to have the right inputs/outputs, and you&#39;ll need to modify the driver code to work with the CS8900.
