question for file download

Hey,everybody,

Here,I have a question for file downloaded. My environment is vxwork
5.5.1 based on MPC 8260.
My work has two downloadable project, such as prject 1 and project 2
which has invoked some routines in project 1.
Now, at first I download project2.out, then download project1.out.
After that, I lanched debugger,and run project1.out. When I run
project2.out, it crash with the errno 0x30065.

My question is what has the vxworks done when a file downloaded into
the
target machine? How does it deal with the symbal table?
I am very appreciate for your answers. Thx

Hi:


It's not clear how your are downloading (via Tornado?), but the symbols
are resolved by the target loader "ld" when you load each module. In
your case, if Proj 2 calls functions in Proj 1, you should load Proj 1
first, the Proj 2. Not sure what errno 0x30065 is - try printErrno
0x30065 in the shell and see what you get. Running without the
debugger, you'd normall jump down to 0 if you try to run code with
unresolved symbols.

Good luck,
lc

Tornado maintains a host symbol table also when you load via it's
tools, and this can be synchronized with the target if you specify that
option when building vxWorks.

Errno 0x30065 means S_taskLib_NAME_NOT_FOUND.
