Diferencess: QNX4, QRTP, Neutrino...

Hi…

(My name is Miguel and I am using my wife’s email :slight_smile:

My system: Gateway 933 MHz with 70 GB hardrive and 264 MB RAM.

My problem(s):

I have worked under QNX4, but have no experience under Neutrino. I
downloaded
QRTP, and this works fine. However, after two days of tinkering around,
it
turns out that I am a bit lost.

-under QNX4 I have multiple machines as different nodes. How do I do
this in
QRTP? (i.e. where is the net table where I list the different nodes with
the
pertinent hardware information?)

-I know that the sysinit file is no longer available under QRTP, but how
do I
customize my init activities? (for example: I have a second hardrive
with more
QNX partitions that I want to mount as /home2, I also init the serial
ports at
a higher baud rate and specific interrupts, and other like issues…)

-QRTP does not recognize my ethernet card, how do I do this manually?
(i.e.
under QNX4 I use nettrap and so on…)

-can I write code in the QRTP machine to execute in a QNX4 machine PC104
based?

-what are the differences between QRTP and Neutrino? I have the
impression that
they are the same, but… are they?

On the side…

I have a 3GB partition ready in the 70 GB drive, but I cannot install
QNX4 in
this partition because it is toward the end of the drive. Basically
FDISK has
problems with just about every thing. I was able to load QRTP in this
partition, but I really want QNX4 instead. Well, any suggestions on how
to do
this??

Thank you so much…

No need to do that configuration now. It’s called QNET on RTP,
to start it, being root and just do a:

mount -Tio-net /lib/dll/npm-qnet.so

You should be able to see everybody who is running this under /net.
Then it’s just “ls /net/” instead of “ls //2” :slight_smile:

/etc/rc/rc.local, if exist, will be execute at boot time. You can
put whatever command in it. Make sure you chmod a+x it.

It also have a nettrap :slight_smile:

No. No cross develop allowed on QRTP, for now.

-what are the differences between QRTP and Neutrino? I have the

Yes. (I thought Neutrino refers to the kernel, QRTP refers to everything,
kernel + GUI + …, but I can be wrong :slight_smile:

Not sure for this one…

Understandable

this in QRTP? (i.e. where is the net table where I list the different
nodes with
the> pertinent hardware information?)

You have to mount the equivalent of QNX4 FLEET, it’s called qnet.

mount -T /dev/io-net npm-qnet.so

This will create a directory call net into which you should see
all the other machine (assuming qnet was also started)

-I know that the sysinit file is no longer available under QRTP, but how
do I customize my init activities? (for example: I have a second hardrive
with more QNX partitions that I want to mount as /home2, I also init the
serial
ports at a higher baud rate and specific interrupts, and other like
issues…)

For the HD you could create a file call /etc/rc.d/rc.local. For the higher

baud rate I would use the stty command and run it inside rc.local.
For changing interrupt I don’t know what is the clean way
to change that.

-QRTP does not recognize my ethernet card, how do I do this manually?
(i.e.

QRTP does not support all the card that QNX4 does, however nettrap

is available. You can try it, but it looks like you have a card that is
not
supported.

-can I write code in the QRTP machine to execute in a QNX4 machine PC104
based?

No, QRTP is for developming Neutrino code

-what are the differences between QRTP and Neutrino? I have the
impression that they are the same, but… are they?

QRTP is build on top of Neutrino. QRTP is Neutrino+Photon 2.0 +

goodies.

On the side…

I have a 3GB partition ready in the 70 GB drive, but I cannot install
QNX4 in
this partition because it is toward the end of the drive. Basically
FDISK has

partition, but I really want QNX4 instead. Well, any suggestions on how
to do
this??

You will probably not be able to boot anyway. However make sure you have
the lastest 4.25D as I beleive some issue with large disk were solved.

Thank you so much…

Ok. I am familiar with the mechanics of QNX4, but new on QRTP. While I
understand the concepts behind the technology, I am not quite sure how
to implement the different commands. For example, when you assume that
qnet was started… how do you do this exactly? Would I see an entry
following a ‘sin’ command? How can I tell what is running? (i.e. ‘sin’
output looks familiar, but with a different unknown flavor’.)

I am a bit lost with this. What is the difference between npm-qnet.so
and npm-tcpip.so? Not quite sure of this, but I’ll do a bit more
reading on the subject.

Also… in QNX4 we have the netmap file under /etc/config. Well… how
do I tell the QNX4 machine to search for the QRTP machine?? I would do
something like

ls //4

since the QRTP machine is assigned the node 4 in the QNX4 machine. I am
not sure what to expect exactly, and so far I have not been very
successful.

In specific, I need to see the QNX4 machine from the QRTP one, and vice
versa. Any help on this subject is greatly appreciated…

Thanks…

There would be a directory call /net

Not realy since qnet is started as a thread by io-net.

How can I tell what is running? (i.e. ‘sin’
output looks familiar, but with a different unknown flavor’.)

I am a bit lost with this. What is the difference between npm-qnet.so
and npm-tcpip.so? Not quite sure of this, but I’ll do a bit more
reading on the subject.

nmp stands for network protocal manager (that was I assume )

If you mount nmp.qnet.so you install the qnet manager. If
you mount nmp.tcpip.so you install the tcpip stack. Futur
protocol should install the same.

the *.so file is a DLL. When you do a mount you are asking
io-net to load that DLL. Inside that DLL there is a init routine
that io-net invoke. Most of the time that init will start one or
more thread to handle the protocol. That’s very efficient
since data between the various layer of io-net doesn’t need
to be copied.

Also… in QNX4 we have the netmap file under /etc/config. Well… how
do I tell the QNX4 machine to search for the QRTP machine?? I would do
something like

ls //4

since the QRTP machine is assigned the node 4 in the QNX4 machine. I am

successful.

QRTP and QNX4 cannot see each other. QRTP does not require a netmap
(finaly)

In specific, I need to see the QNX4 machine from the QRTP one, and vice
versa. Any help on this subject is greatly appreciated…

Can only be done via TCP/IP (NFS, Samba, telnet, etc)

Thanks…
