CS8900 Interface to NIOS II

i'm pretty sure that uclinux doesn't care about or use altera's hal. it has its own drivers. altera's hal tries to simulate a filesystem, which is redundant in uclinux, where you have a real filesystem (not to mention an entirely different driver model).

that said, when you say uclinux has a driver for the cs8900, do you mean that there is support for the cs8900 under the nios ii/avalon bus architecture? i mention this because there are lots of drivers for the pc architecture that aren't compatible with the avalon bus architecture. the easy way to find out is to configure a linux kernel and see if there's an option for the cs8900.

This is exactly the information I was after, thank you!

Yes, there is specifically an option for CS8900 when configuring a uclinux kernel. There are a number of options, including some of the IP Mac&#39;s and some more established devices, I think I recall the RTL8019 as well.

Thanks again!
