Embedded Linux >> Newbie - How to download object files on a running system? - MPC860

Hi,


I'd like to download the total software image and then want to add a
module (.o file) to the image during runtime. I do not want to disturb
the existing/working image.

I'm using Cross compiler ccppc version cygnus-2.7.2-960126 egcs-971225
tornado 2.0 on Solaris Machine and my development machine is Windows
NT with Tornado 2.0

Could you please let me know, how to add .o files to the existing
image during runtime?

I want to be able to compile and create the object (.o files) files on
my windows development machine and download the same to my target
VxWorks machine without affecting the existing image.

I'm able to download either complete image or just object file, but
not both of them together.

In the worst case, I want to be able to switch from the image to the
object file that I downloaded and vice versa from VxWorks prompt.

I am looking for something similar to 'insmod' that allows us to
insert modules to the working kernel/image. It worked for me with
uCLinux Embedded OS.

Regards
Arun

I don't think this is possible. I suppose you should upload a complete
additional program (elf file) and have the running application start it.

Hi,

Why dont you use the target server to load the object file!!!
Ref., chap 8 in tornado users guide...
and do post your findings and observations!!!

Ftp the object file on your flash (if you have any). then load the
object file using the ld < file.o command. If you are booting using
the network, you can load directly from the network.

Then run the main function in the loaded object. This is usually the
routine that spawns the task.

4. object files, header files, source files? 

I can't find any books describing the anatomy of C/C++ programs. What is 
an object file? Can it be generated from a header file?, what is 
linking?, why does a source file need an object file? etc.

I have looked in The C programming Language, The C++ Programming 
Language, Accelerated C++, GNU make etc but they don't describe these 
basic subject. Any literature that covers these subjects?

8. /proc file system newbie 

Hi Gang,

I am a UNIX novice programmer :-) I have a task in which I have to create my 
own /proc entry  that monitors or controls some aspect of the kernel.  I 
need to be able to, modify the kernel to either record some information or 
enable you to view some information, add a proc entry that enables users to 
obtain this information, and
have the proc entry enable you to reset or modify some information.

I am running a Solaris 5.8 os. I have begun reading about the proc file 
system and it all seems new to me and I am a bit lost :-(
Any resource/example of any kind would be invaluable to me and the help 
would be greatly appreciated.

Thanks

Ashutosh
