Hi!
I have a couple of questions:

  1. Is it possible to build QNX 2.24 system (like embedded) with TCP/IP
    network without filesystem?
  2. I need to write netcard driver and it should interact with standart
    TCP/IP stack. What requirements my driver should complain with?

Thanks
Rustam

QNX 2.24???

I assume you mean 4.25, or 4.22?

Not really, that is not a requirement of TCP/IP but TCP/IP will not
fit in the ./boot file. Thus you need some sort of FileSystem to
load tcpip from, but this could be a flash or floppy. Or you can boot
remotly from another machine.

  1. I need to write netcard driver and it should interact with standart
    TCP/IP stack. What requirements my driver should complain with?

Three options:

  • Check out /etc/readme/technotes/net.fd
  • TCP/IP 5.0 (still in beta) as an interface to send/receive packet
  • Talk to your QSSL sales rep to try to get the source to a Network driver
