Wanted to relate an experience regarding QNX and the use of an industry pack
(IP) quad carrier board in a cPCI system. IP’s are small I/O function
modules that
come in different flavors to provide A/D, D/A, discrete I/O, counter/timer,
etc functions.
We’ve successfully used Acromag carrier boards in a PCI, DOS system and went
with their ACPC8625 quad carrier board for a new cPCI system that would use
QNX. cPCI and QNX are new frontiers for me. My system utilizes a Concurrent
Technologies single-slot 500 Mhz mobile Pentium III board.
‘pci -vvv’ command showed that the carrier board was being mapped to ‘bus 1’
pci out through a pci bridge chip on the processor board. The carrier board
was being seeen and reported by this ‘pci’ command. Test code showed that
only 3 of 4 IP’s could be read on the Acromag carrier board which utilizes a
PLX 9050 pci chip. This was not good.
QNX and Acromag were alerted to the problem but no solution was forthcoming.
Lucky for me, Alphi Technology also makes a quad IP carrier for the cPCI bus
(CPCI_4SIP) and were local to the Phoenix area where I work. They were kind
enough to let me borrow their board, which utilizes an AMCC pci chip. Test
code revealed that this carrier board seemed to function properly in the
‘bus 1’ mapping – all IP’s were successfully read.
I am now the proud owner of an Alphi quad carrier board and am continuing
down the QNX road, which I was afraid I would have to abandon.

I’m glad to hear that you found a board that lets you continue to use QNX
for your project. I’m sure you won’t regret it. I’m interested, however,
in hearing what you meant by “no solution was forthcoming”. Was the problem
too intractable to be solved in a timely fashion? Was your problem given
due attention by our support staff? I’m curious to know what your
experience was like in this situation: do you feel that a your problem was
properly dealt with? We’re always concerned about our customer’s experience
in dealing with us and any feedback you can give is invaluable.
cheers,
Kris
