You haven't mentioned Linux before so I assumed you had a board with a
monitor or something (an embedded target).

How did you configure your gdb after all (i.e., what was the configure
command you used)?

Have you run make install?  What is in your bin directory?

I have the file gdb 5.0 . I had to make changes in the gdb/makefile to
enable the target rdi debugging.

When I had done ./configure in the main directory, it was configuring gdb
for host i686 and target also i686, where as I want the target to be my
Cirrus Logic Arm 7500FE Baord. I do not know how to sepcify the exact
option for this arm processor. Currently the board has only the ANGEL
debugger program running.

I already have the vmlinux, and the zImage files for the Linxu kernel
2.3.99 . My host PC is RedHat 6.1 and i686 architecture.

I am using the gdb mainly for downloading the image files into the RAM on
my target baord from my Host PC.

I hope you could provide me with some suggestions.

Thanks

You should not change anything.  Use the original gdb 5 tar file.

No changes are necessary to debug Angel targets.

But this is irrelevant (see below).

Again you did not send me the configure command that you used.
However, it is clear from your description that you did not read the instructions
on how to build it.  Please do so before asking for help on the net groups/lists.
(Read the FAQs as well when they exist).

Your configure line will need a --target=arm-elf   or  a  --target=arm-coff
for the kind of board you have.

But, again, it won't do what you need...

You are definitively in the wrong track AND in the wrong list.

The zImage file is not in a format that gdb can understand.  
vmlinus is (elf) but this is of no use to you.

I'd suggest you look at LILO (the arm version or arm equivalent of it) and
try to write some boot ROM code that either does what it does or loads it
from floppy or something.

But this is a topic for the ARM Linux mailing list.

Title: RE: Suggested (easier) fix to ... RE: Regressions problem (200 fa ilures)



And a 
bit more... the rebuild/regression did succeed (after some 
tweaking)
and 
the problem with __main is in the current CVS as well.

  Mark:
   
  I just tried to rebuild with my interim patch in place, and found that 
  RTH had completely
  rewritten the area.  If I don't run into too many ICEs during the 
  rebuild of the compiler
  suite (it comes and goes regularly depending on who has patched what) 
  I'll know
  something tomorrow (Fri) about what effect his changes had on this, but 
  from
   looking at the code, it may have the same problem.  (I'm 
  skipping my patch for the moment.)
   
  Richard: quick synopsis: the code in this area doesn't (didn't?) take 
  into account the
  possibility of there being a call to __main, with the consequence that 
  the initial
  breakpoint for main ends up at the {, rather than at the first statement 
  *if* the
  call to __main is generated.

    Touche. 
    OK, now I understand the problem -- thanks to you.  
    I'll look back at why I did what I did -- and then 
    see if I can figure out how to fix it. 
    Thanks for bearing with me on this.

ARM TARGET

[Lavu Sridhar]

I have downloaded the gdb 5.0 How do i configure for a target of arm7
processor. I am using Cirrus Logic CL7500FE Arm processor as my target.

configure it to arm-elf or arm-coff, depending on your preference for file format.

When compiling specify that your CPU is an arm7 one with -mcpu=arm7

Another parameter you may want to check is -march
The default seems to be armv5.

Thank you for the mail.

I have complied using the arm linux cross tool chain (binutils 2.9.5.0.22)
and have the vmlinux file. 

Using the gdb 5.0, I want to load the image into the CL7500FE processor.
How do I configure the target as my 7500FE processor? Do i give the
option:

./configure --target=arm-pc-linux-gnu

or some other option?

regards,
Lavu Sridhar
