[ECOS] arm-elf-gdb does not work

[Mildred Frisco]

Hi !  I am having a problem with my arm-elf-gdb.  I produced an application
hello.elf and downloaded/tested it using arm-elf-gdb and it worked.  I built
another ecos with net test configuration.  I wanted to use the test programs
produced but when I ran arm-elf-gdb the program did not work.  The memory
window (I think it's the memory window) in arm-elf-gdb appeared for a while
and then back to the prompt.  What seems to be the problem ?
Thanks.

My guess is that You are debuuging via ethernet, am I right? In that case You 
must use a diffrent IP for RedBoot and eCos net.

[ECOS] arm-elf-gdb does not work

[Warren Postma]

Reply to Mildred Frisco:

(a) what exact version of arm-elf-gdb are you using? binary or compiled it
yourself?  If you compiled it yourself, please post your "configure"
statement.
(b) Please give more information on your target hardware.

Try the text mode:

arm-elf-gdb -nw <exename>

# Make serial connection:
tet remotebaud 38400
target remote COM1
# Get the code running and up to the first line in main:
load
break main
c

Then see if it gets to the first line of main, and type S to single step
through the code. That will establish whether the NON-GUI version is
working, and your target environment is working. I am having a lot of
trouble with the GUI version of arm-elf-gdb 5.2, and my target is a
StrongARM 1110 based NanoEngine.  Also, like you, hello-world is a lot more
stable even under the GUI, than larger EXEs.  I think that there is a
serious bug in INSIGHT 5.2, which may be fixed in latest CVS sources, but I
haven't gotten them to build yet.

If you get this far, may I suggest that the problem is that only recently
(version 5.3 and later) has the GUI version developed stability with remote
ARM targets.  I have mixed results with my StrongARM "nanoEngine" target
here.

The fact that the network stuff was linked in gives me a hint, in that
larger and more stressful applications appear to be having problems, but
Hello World programs are working fine for me also.    Our experiences are
not to different here, and the thing we have in common is we're probably
both using arm-elf-gdb 5.2 or lower, and both using arm targets.  HMM.

I am following this up on the INSIGHT mailing lists also.

Regards,

Warren Postma

[ECOS] Build standalone application in E7T

[peter_ku]

Hi,

Any one have ever generate a standalone application, put into E7T's flash and run successfully?

I follow the following sequence to generate a binary file, and I can put it into flash successfully, I means I use "rommodules" and see my application in the 0x1820000.
But It looks something wrong to execute my application code.

1. Choose ROM type, and build eCos library.
2. I edit title and help string in the redboot_module.c, and remark the latest line.  //_RedBoot_init(__dummy_init, RedBoot_INIT_LAST)
3. compile my application and redboot_module.c
4. Link all together to generate binary file.
5. Generate the final binary file with checksum.
6. uuecode the binary
7. put it into 0x1820000

Any suggestion , thanks a lot


Best Regards,
Peter

I really doubt it - I think your problem is more a fundamental
serial I/O issue.

Well, shoot.  Perhaps that's part of my problem too; though, trying the
text-mode commands you've indicated, I get *slightly* different errors than
before - and perhaps more helpful ones.  With debug remote turned on, at the
end of the communication (after several packets transfer back and forth) I
now get:
Couldn't establish connection to remote target
Cannot access memory at address 0x1110fff7
