Boot script for TCIPI

QNX DEVELOPERS Porting
1

Dear all,
I was using a PC/104 (advantech.net.au/products/PC … C91D8.aspx) for my project. it only has 1 ethernet port. My boot script is working fine.

However, I have got a new PC/104 (advantech.net.au/products/PC … 36A1C.aspx). I tried to apply the same boot script for this new PC/104. However it gives me error said that:
ifconfig: SIOCGIFFLAGS en0: no such device or address

I don’t know how to fix this. May I get some help please? Thanks a lot
Donald

These programs need to be run only once from the boot image.

“data=uip” will waste less memory as the RAM from the boot

image will be used directly without making a copy of the data

(i.e. as the default “data=cpy” does). When they have been

run once, they will be unlinked from /proc/boot.

You are using the speedo network driver.

I think that you want to use the e1000 driver.

Thanks Maschoen,
I have modify the code to the following

#   ## network driver: Substitute your IP address for x.x.x.x         #

       qconn port=8000



devup-e1000.so

But this lead me to another problem.
I was using a QNX 6.4, the boot up script gives me the same error.

I have installed QNX 6.5 into another computer (both Neutrino and Momentics)
I create the boot drive again, the network finally works (I can see the device on Momentics)
However I tried to run the program on Momentics. It gives me

“ldd:FATAL:: Could not load library libsocket.so.2”

Then I added libsocket.so.2 into the boot script
This time the boot up gives me

“syspage memory request of 65567 exceeds maximum of 65535 bytes”

How should I solve this two problem?

Thank you very much for your help.

I don’t know what the “syspage memory request” problem is about. The libsocket.so.2 problem probably has to do with which OS you compile under vs. which you run under. If you are going to run on 6.5, then compile with 6.5.

I assume you don’t literally mean you ran the program under Momentics, since that would mean you are trying to run a QNX program on a non-QNX os. Did you mean run the program from Momentics on a target system?

5

Yes, I am building and run the program from Momentics (IDE4.7) on a target system (6.5).
How can I compile it with 6.5? I am using a Window host.
I have read (qnx.com/developers/docs/6.4. … incfg.html)
I went to the QNX Software Development Platform 6.5.0 > Configuration> Chose "QNX Software Development Platform 6.5.0 "
Then I also checked My Computer > MAKEFLAGS : -IC:/QNX650/target/qnx6/usr/include
the libsocket.so.2 error still appears

Thank you very much for your help

I’m not an expert when it comes to using Momentics. I do almost all of my development self hosted. That said, on my Windows system I see in my root directory C:\QNX650. Is that what you have? The momentics I have loaded is 4.7, the same version as yours. If you have only QNX650, then I’m without any advice. If you have only QNX641, then you obviously do not have The QNX 6.5 development loaded on your Momentics machine. If you have both, well there’s probably some menu/configuration option somewhere in Momentics that you have to find.

The only other thought that comes to mind would be to search the C:\QNX6?? directory for the missing .so file and copy it to the /lib or /usr/lib directory on the target.

7

I have two computers. One of them is QNX6.5 only, the other one has both QNX6.5 and QNX6.4 both of them give me the same error. Both of them missing the libsocket.so.2

I tried to copy the libsocket.so.2 to the target though Momentics but Momentics does not allow me to do that. Do you have any other method to copy libsocket.so.2 to the target?

Thanks

8

That is very strange. Copying a file to a target system is a very basic function of Momentics.
The other way to get the .so file over is to recreate your target image, this time including the file and then reload the image.

9

I believe I am copying the file correctly. I opened up the window contains the libsocket.so.2, then drag and drop the file into Momentics window of target/lib it gives me an error “Copy operation error: C:\QNX650\target\qnx6\armle\lib\libsocket.so.2 No such file or directory”

If I rewrite the boot script with libsocket.so.2 it gives me the error “syspage memory request of 65567 exceeds maximum of 65535 bytes” during boot stage

10

“Copy operation error: C:\QNX650\target\qnx6\armle\lib\libsocket.so.2 No such file or directory”
That means you are trying to copy to a read-only directory. You probably have to put it in /tmp.

If I rewrite the boot script with libsocket.so.2 it gives me the error “syspage memory request of
65567 exceeds maximum of 65535 bytes” during boot stage
Sounds like your ifs has grown too large.

11

I can copy the folder into /tmp. But I cannot move the folder around (e.g. /lib, I do not have permission to move into /lib). So Momentics still gives me the same error.

I found someone have similar problem (openqnx.com/newsgroups/viewt … 12&t=21986), but they did not follow up the answer

12

Is it possible that /lib is part of the .boot file?

13

Copy to /tmp, then add /tmp to LD_LIBRARY_PATH.

14

I added /tmp to LD_LIBRARY_PATH
then manually copy libsocket.so.2 to /tmp
and it finally works
thanks alot
