Problem with 2 net drivers

I’m trying to run 2 drivers under Qnx4.

I using a 3COM 509 on en1 and a Realtek controller on en2.

I can run either controller separately on en1. When I try to
ifconfig the Realtek controller on en2 I get “ifconfig: ioctl
SIOCGIFFLAGS): no such interface”.

I’ve started Net.rtl with the -l 2 flag so I was expecting to be
able use en2.

I turned on the verbose option to Net. After each driver loads
I get “Net: Runtime Error 0056”. Then after Net.rtl runs I also
start getting “Net: Runtime Error 0037”.

Can someone tell me what these runtime errors are and
what I might be doing wrong?

Thanks,
Carlos

I’m not in front of my QNX 4 system right now, but it seems that both
invokations would try to access the same hardware. Check the
programs parameters, and look for something like a -P (PCI SLOT)
option, or a base address parameter.

I did set the base address for the 3com driver. I know the Realtek
driver works without args on another QNX system using the same
single board computer.
It turns out that if I run Net.rtl first I can set it to en1 or en2
and run the 3com driver afterward.
It makes me think there is an address conflict but I don’t know
what addresses the Realtek controller uses.

I’m still getting the Net: Runtime Errors 0056 and 0037.
Can someone point me to some documentation that explains
these errors.

Thanks,
Carlos

netinfo -a

This will show all the error messages. To filter out what you’re looking
for, you might try:

netinfo -a | grep 56
netinfo -a | grep 37

I’ve met some troubles using TCP/IP with 2 Net.* cards also.

See “Net+Socket enumaration bug” subj in this newsgroup.

My recomendations:

on clean (no Net & Socket running, net cables disconnected) system manually
start

Net &

Run first ‘Net.XXXdriver -l1’ and ‘netmap’ to inspect it’s MAC adress
Run second ‘Net.XXXdriver -l2’ and ‘netmap’ to inspect it’s MAC adress

add ‘netmap -m’ entry for some QNX4 PC.
Test QNX4 net. OK?

Run Socket
ifconfig en1 …
connect the net cable and ping neighbour PC. OK?

ifconfig en2 …
connect next net cable and ping neighbour PC. OK?

With ‘arp -a’, ‘netstat -i’ you may check MAC addresses for en1 and en2.
They both must correspond to the ‘netmap’ output.

Fixed the problem. There was an overlap of i/o addresses.
I was working blind since I didn’t have the addresses of
the Realtek chip.

Thanks for all the help.

I have found that with some of the newer QNX4 Net.xxxx drivers, they
take about 10 seconds to register. Putting a ‘sleep 10’ after the
Net.xxx driver in the sysinit usually clears this problem.
