As I mentioned in a previous post we are developing a system which uses
several Ampro 386 core modules running QNX and talking over ethernet. We
are using the Ampro ethernet cards which are NE1000 clones. These cards
are the only ethernet cards I am aware of which are available in the
PC/104 form factor.
Anyway we are developing on a six node QNX network. Three of the nodes
are using the Ampro cards the other three nodes are desktop machines. We
have run into a curious problem which I was hoping someone might help us
solve. The Ampros communicate just fine on the network until we reboot
them (either via software "shutdown" command or actually hitting the
reset button). After they reboot they absolutely will not talk on the
network. Every attempt results in a "No route to host" message. To
restore communications we actually have to turn the Ampros OFF and then
turn them back ON! The desktop machines don't suffer from this problem.
They reboot and come up talking.
Now this sounds to me like a Ampro hardware problem, not a QNX problem.
I remember QSSL was running QNX on an Ampro at the Sept '94 Embedded
Systems Conference so I thought they might have some experience with
this. I have not talked to Ampro yet but that is on my list of things to
do for today :)
Any help would be aprecieated!
