My preference is to write RTLinux drivers that use "human assisted" discovery. If you have a Linux driver or system, then it is not so hard. Use /sbin/lspci -v and /sbin/lspci -b to get the important data. Put this in a header file. Write a simple RTLinux driver that does not use complex Linux interfaces. If you need to run it on another system, use lspci again. The Linux PCI driver is designed to work on every possible machine configuration and requires dynamic discovery: RTLinux drivers often do not need this. > > > At 01:34 PM 6/4/2002 -0500, [EMAIL PROTECTED] wrote: > >Does anyone have any advice or (more preferably) examples > >of a PCI device driver written for RTLinux?
