Modifying Nios II Device Drivers lan91c111?

Altera_Forum · ‎09-24-2004

Hello all...

I would like to create a new dm9000 device driver instead of lan91c111. What I need to know is how to go about creating it and getting it to link correctly thru Quartus II and the Nios II IDE.

Any ideas?

Thanks in advance...

Hello maoguohua2002,

As I wrote in the topic http://www.niosforum.com/forum/index.php?a...ct=st&f=2&t=421 (http://www.niosforum.com/forum/index.php?act=st&f=2&t=421) I’m writing a HAL device driver for the DM9000 from Davicom. The driver will be supported from the stand alone lwip in 16-bit mode. No support for MicroC/OS-II RTOS!

I started to edit some files of the LAN91c111 component in the directory “niosII/components/ altera_avalon_lan91c111”. That’s a good starting point. When it is working correctly I will share my stuff in the forum. But now I don’t have a lot of time to make this thing doing! Perhaps someone could handle the low level routines. The other things are done.

Bye,

niosIIuser

There's a section in the manual on how to write ethernet device drivers Chapter 5 page 12 is the start of the appropriate section though you should probably read the whole chapter.

Hope that helps.

The manual I was referring to was the Nios II Software Developer's Handbook. This can be found in the documents directory and is called n2sw_nii5v2.pdf
