Good afternoon,

I am having trouble with a peripheral card developed in house; lets
call it CCA. This card uses a PCI interface defined as the data
acquisition class. Upon cycling the power on the system, I get the
following messages from the sloginfo utility.

Any suggestions to avoid this warm reboot? I have
added a delay in the boot image before calling pci-bios, thinking that
the error might be related to the on-board FPGA not being loaded. But
this approach did not correct the error.

Once the warm boot is completed I have access to the card and can
control it successfully.

Thanks in advance for your help

Now the device is well configured.

Looks like you only have a Pluf&Play RUN in your IPL, if you warmboot?!
If this is a x86 PC, have you switched off “PLUG&PLAY OS” in the bios?

Any suggestions to avoid this warm reboot? I have
added a delay in the boot image before calling pci-bios, thinking that
the error might be related to the on-board FPGA not being loaded. But
this approach did not correct the error.
This approach cannot help, because you must have loaded your FPGA before

the “PLUG&PLAY RUN” is made. AFAIK the “PLUG&PLAY RUN” is made by IPL
and not by the pci-bios resource manager.

Once the warm boot is completed I have access to the card and can
control it successfully.

Good afternoon,

On an x86 machine, our pci server (pci-bios) lets the machine’s
PCI-BIOS find and configure all the various I/O cards, then it
just asks that BIOS what the configurations are.

The fact that the soft reboot allows the card to be properly
configured suggests that something on the hardware/firmware
side is not configuring properly.

It may be that your idea about a delay to allow the FPGA to
initialize is correct, but if so, it would have to be a delay
before the system’s PCI BIOS does its configuration, rather than
before any QNX components run, so introducing a delay in the
boot image will be a delay that is too late, after the problem
has already happened. Can you try booting the machine from
power off, and instead of letting it boot, throw it into the
BIOS configuration screen, leave it there for a few seconds, then
continue with the boot?

Another thing that might be worth trying, would be to see whether
the behaviour is particular to the PCI BIOS on the current machine,
and try this on a different machine. (One that would have a different
BIOS.)

Any suggestions to avoid this warm reboot? I have
added a delay in the boot image before calling pci-bios, thinking that
the error might be related to the on-board FPGA not being loaded. But
this approach did not correct the error.

Once the warm boot is completed I have access to the card and can
control it successfully.

Thanks in advance for your help

Thank you for the replies.

The system used is a x86 machine, using an Intel 855GME R2 chipset.
I did not see references to the Plug&Play in the bios other than
PCI/PNP ISA UMB region exclusion. I will investigate developing an
IPL for this card.

I have tried to throw the booting process into the BIOS configuration
screen before continuing the boot process without changes.

Finally the time delay was placed prior to calling pci-bios in the
ifs file. Once again, this approach did not correct the detection
of the pci peripheral.

The investigation continues. Thank to all for your help, much
appreciated.
