Hi guys,
So i have looked but cant find an answer to my issue.
Im very new to this and its my first project.
Im using Eclipse Kepler on Ubuntu.
I have Embedded GDB as the debugger and Zylin Native, and Openocd.
When i start Flash and Debug, it seems to work, and goes to a (Suspended) states. Then i press 'Resume', and then it terminates with:
<During startup program exited with code 126>
If i run GDB from Terminal, i get the same thing, and it says Permission Denied.
But if i type into Terminal:
"Gcc -g main.cpp -o main.o"
And then go through Gdb, Run, etc, it 'Reads from directory (or something)' and then says:
"Starting Program" but then Terminal just stays saying that.
Any ideas how to get the debug to work in Eclipse?
I've made sure all files are allowed to be executed, chmod..., but not sure if my 'mount' is, my fstab file says nothing about my user or mount.
Thanks in advance, and leymans terms please as i dont know the jargon.
Dan

**Update**
Ok, so i read somewhere about the 'GDB Script', found under:
Debug Config >> Zylin Native >> Debugger >> GDB Script
I can't find GDB script, im assuming that it means the GDB Command File??
So i changed the GDB Command File (which was blank) to: gdb/stm32f407vg.script
Now, when i flash and debug, it seems to actually do something, but still getting an error:
source gdb/stm32f407vg.script
warning: Architecture rejected target-supplied description

set protection for sectors 0 through 11 on flash bank 0
requesting target halt and executing a soft reset
*** stack smashing detected ***: /usr/bin/gdb terminated
So it looks like it doesn't like what i put into the command file, but it does seem to 'write' to the board, i think. (If you look up a few lines, it says: wrote 1708 bytes...)
Any help would be great, i think theres something in the command file bit which is right as it does seem to write, but wrong because it doesn't like it, and it does then terminate GDB after writing.
Thanks,
Dan
(PS I'm doing this project as a task to get a job interview as an apprentice in a robotics company, i've got a HNC in Electronic Engineering but we only did about 4 weeks worth of Visual Studio C++ programming.)
Just to add, Although i'm still coming up with that error, i am succesfully Flashing the STM32 Board, although i cannot Debug and see what is happening in reak time.
