Hi,

I'm trying to write a device driver for a PCI card under OS4pre, but I can't seem to activate the card's memory-mapped IO space. I've locked the device and called WriteConfigWord(PCI_COMMAND, PCI_COMMAND_MEMORY). Do I need to do more? At the moment I just get eg. 0B0B0B0B throughout the card's IO space.

@ncafferkey

Normally, U-Boot should already have configured the card. If the card properly flags one of its BAR's as I/O, it should have the I/O bit in PCI_COMMAND enabled as well.

Make sure that you use the InByte/OutByte (or Word or Long) for that.

What kind of card is this?

It's working now. I noticed that UBoot 1.0.0's 'pci' command wasn't listing the card, but PCIScan did, and I'm sure I was accessing the right card in the driver. I moved the card to a different slot and it worked. It had been in the slot next to the AGP slot on my A1SE (that's the 66MHz one, isn't it?). Thanks for the UBoot hint.

It's an 11Mbps wireless network card.

Good luck with it. The more drivers the better!

RIP my A1XE.. that used to have an appetite for batteries!

Absolutely... drivers will be pivotal.

Myself I want to write drivers, but I need native P96 libraries before I can really do so (determined to get WinTV card working on it!). I know I'm not the only one wanting to do so, though....

@ncafferkey

It's an wery good idea to make WLAN driver,good luck with your project :)

How about setting up a webpage listing drivers in progress?

A driver repository ...

This way, efforts can be directed to devices not yet supported without wasting energy for several writing drivers for one device.

Just a thought.

@gnarly

and USB-bluetooth dongles...

and....
and....

So keep them coming !

I think Bluetooth is a different matter entirely.. it's not just a matter of a driver, more a communication package, I suppose... not that I really know much about bluetooth, to be honest, but it's more than just a driver I'm sure.

A 54Mbps WLAN card, however... that is just a driver - a SANA-II one at that, I suppose, so quite well specified.

However, I agree there should be a repository for open-source drivers, where people can report their successes, and work on drivers... it would be very useful! I have the webspace, but not the bandwidth or the time - how about someone on this very board, or else intuitionbase?

@Spirantho

The source code to the Bluez bluetooth stack would probably be a good place to start.

When I come to think of it, Universal Space is made for exactly this. It will cost a little something to get a project going.

If I can get the benefit of a driver or two when my time comes, I will happily chip in a few cents.

But it doesn't cost anything to ask. I will send a question tonight.

Ah yes, the 66MHz PCI slot doesn't work when there is an AGP card inserted, and it doesn't clock back to 33Mhz. Some cards can take it (some Voodoo models for example) but many cards fail to work properly.
