Hi everyone, 

 

i have custom board with an Intel 82540EM gigabit ethernet controller. Now i want to integrate it in uClinux. My question is how to do this in uClinux and nios. Did anyone do something like this before (interfacing a pci device in general). Are there any issues that i need to know? 

 

I know i need a controller: I want to use the pci controller from OpenCores.org. Afterwards i will have to modify or writing drivers. 

 

 

Any hints, tips and information to start would be great 

 

Thanks a lot

I wrote the PCI driver for Altera pci bridge based on the pci host brdige sample hardware design,

It still need some clean up. And I will post it in the buildroot guide soon.

Hello Hippo, 

 

I'm happy to hear that someone is already working on this. If your driver is really available i would use the altera pci bridge. This would save me a lot time. 

 

Maybe you can tell me something about your driver, so i can start working on this driver for the ethernet controller. I won't have a problem if your driver code is dirty. Forgive me, i don't like waiting... and to be honestly i don't have much time to achieve this part of my project.  

 

Thanks a lot...

There are still some problems in flushing cache. 

Working fine without dcache in nios2. 

I am working to resolve this issue.
