Problem on mounting driver .so   
Hi,

I have modified the sample ethernet driver.

when i load the driver 

mount -T io-pkt wm0 -v /lib/dll/devnp-sam.so

the following error i got

Parsed: mount from [/lib/dll/devnp-pe.so] mount on [NULL] type [io-pkt]
mount: Can't mount / (type io-pkt)
mount: Possible reason: No such device or address

Please help me on this ,why mount on NULL is coming,
can you please tell the reason.

Thanks and Regards
K.Senthil

That doesn't look right.  Should be something like:

# mount -T io-pkt -o "name=wm,unit=0" /lib/dll/devnp-sam.so

The -v is going to the mount utility, not your driver.

Check out the 'How do I debug a driver using gdb?' section
of this page:

http://community.qnx.com/sf/wiki/do/viewPage/projects.networking/wiki/Drivers_wiki_page

You should be able to step through and see exactly
where the ENXIO is being raised.  Also check the
sloginfo.

Problem mounting lsm-autoip.so in QNX 6.4.1   
Hi,

we load the lsm-autoip.so in QNX 6.4.1.

mount -T io-pkt -oif=wm0,debug lsm-autoip.so

It throws Symbol not found.

But its working in QNX 6.4.0.

so we copied the lsm-autoip.so from QNX 6.4.0 to QNX 6.4.1 then
it was working fine.

So please help me on this.

Thanks and Regards
K.Senthil

If the symbol was report(), this was just fixed recently. It would be
available on the foundry.  trunk/sys/lsm/autoip
