QNX RTP (Writing Device Drivers Need Help!)

Hi Guys/Gals;
I have been looking all over the Internet and I simply can’t seem to
find complete information on how to write a QNX RTP device driver. I
understand that I probably need to create a resource manager to communicate
with the PCI board that I want to use. The problem is that I can’t seem to
find any clear cut examples of how to do this and worse I can find any Books
in my area or any how to guides on the Net. All the books I have seen are
all on back order for 5-6 weeks!!! Can someone please help me? Even if you
could just point me to a URL or two, that would be great.

Thanks,

Chris

All the books you have seen??? As far as I know there is only one book
and it’s from Robert Kertn, www.parse.com

Can someone please help me? Even if you
could just point me to a URL or two, that would be great.

The online doc contains most of the information you need, There is probably
no example you can cut and past but it’s there.

Check out http://qdn.qnx.com/support/docs/neutrino_qrp/prog/resmgr.html
and the pci familly to handle mapping of the pci device
http://qdn.qnx.com/support/docs/neutrino_qrp/lib_ref/p/pci_attach.html

There is an article on resmgr at

Thanks for responding to my question so quickly…:slight_smile: I am looking over the
info now.

I have been looking all over the Internet and I simply can’t seem to

Using the resource manager framework is powerful and may result in a cleaner
implementation but you don’t necessarily have to be a resource manager to
be a driver. You may want to perform simple device io with the card first,
then
turn it into a resource manager later.

Two functions you may want are pci_attach:

http://qdn.qnx.com/support/docs/neutrino_qrp/lib_ref/p/pccard_attach.html

and mmap_device_io:

http://qdn.qnx.com/support/docs/neutrino_qrp/lib_ref/m/mmap_device_io.html

Also you might want to read up on ‘pci-bios’, the pci server program, and
‘pci’:

http://qdn.qnx.com/support/docs/neutrino_qrp/utilities/p/pci-bios.html
http://qdn.qnx.com/support/docs/neutrino_qrp/utilities/p/pci.html

The problem is that I can’t seem to
find any clear cut examples of how to do this and worse I can find any
Books

There are some Driver Development Kits (DDK) that will be released soon.
Also ‘Building Embedded Systems’ by QNX and ‘Getting Started with Neutrino
2.0’ by
Rob Krten are the references for resource managers.

in my area or any how to guides on the Net. All the books I have seen are
all on back order for 5-6 weeks!!! Can someone please help me? Even if you

good luck

Getting started with QNX Neutrino 2 A Guide for Real-time Programmers
by Rob Krten
ISBN 0 -9682501-1-4 Available through Amazon.com

Has a good section with examples. You can also find some at

http://support.qnx.com/support/docs/neutrino_qrp/prog/resmgr.html

Good luck! I wrote one that did some simple read write io-devctl stuff
and it was pretty easy.

While there is plenty of information on writing device
drivers, some of the interface specifications, eg. disk
net, are not released yet.
