Create EFS using Momentics   
Hello friends,

I am bit new to QNX. I have installed Momentics on the Windows system.

I have freescale's MPC8323ERDB board and I am able to create .ifs image (from the BSP) and able to add my project's 
binary and run it successfully on the board.

But the problem is that every time I modify my project and create binary, I have to add it into ifs through project.bld.
 and restart the QNX. And ifs is read only too. I am not able to create log file either :-(

Is it possible that I boot NFS file-system from the Windows(or Linux). Like we can boot Linux kernel image and file 
system through NFS from the uboot.

So that all I have to do is add and remove project's binary into NFS file-system and run it. No need to restart the QNX.


Please let me know if there is other solution to this problem other then NFS. That would be very helpful...

Thank you very much

Re: Create EFS using Momentics   
Sorry my topic title is "Create EFS using Momentics".

This is because Initially I thought about only modifiable file system. But according to my understanding Even in case of
 EFS I have to load project binary file again and again.

Build file for IFS is available into BSP. But Is there any ready build file available for EFS for MPC8323ERDB board.

Again thank you very much...

Hi, Apurva,

The Momentics SDP provides drivers for NFS v2 and v3, as well as CIFS (Samba).  Consult the documentation for details of
 how to get these up and running on your target system:

http://www.qnx.com/developers/docs/6.4.1/neutrino/utilities/f/fs-nfs2.html
http://www.qnx.com/developers/docs/6.4.1/neutrino/utilities/f/fs-nfs3.html
http://www.qnx.com/developers/docs/6.4.1/neutrino/utilities/f/fs-cifs.html

With these, you should have what you need to mount a filesystem from your development machine onto your target.

HTH,

Christian

Re: Create EFS using Momentics   
Hi Christian,

Thanks for quick reply.

I read fs-nfs2 and fs-nfs3 description.

It says that, The fs-nfs3 filesystem manager is an NFS 3 client operating over TCP/IP. To use it, you must have an NFS 
server. 

So I tried to install NFS server according to this: http://www.qnx.com/developers/docs/6.4.1/neutrino/user_guide/
fsystems.html#NFS

When I tried to run nfsd it showed error there is no /etc/exports file. So I created exports file too. but again It 
showed error that It can not create some file most probably because it is ifs is read only...

So please tell me, Am I on the track or missing something...

Thank You

Re: Create EFS using Momentics   
Hi, Apurva,

You need to run an NFS or CIFS server only on your development host, which is to provide the files remotely to your QNX 
target.  On the target you should need only to configure and mount the fs-nfs3 driver to implement the NFS client.  As 
it creates an entirely dynamic filesystem, I'm not sure that the read-only-ness of the IFS should be an issue.

I'm not particularly knowledgeable in this area:  for better help, I'd suggest asking in the networking and/or 
filesystem forum.

Cheers,

Christian
