Running application in non debug mode - Eclipse GCC

the radioman stuffs are for semhosting. If you wish to use semixosting, set the debug option for OpenOCD and in your code add the initialization.

extern void initialise_monitor_handles(void);

int main(void) {
    initialise_monitor_handles();

    printf("hello world!\n");
 }

Semihosting environment requires debugger to be connected because it works as stdio input/output. So if any stdio function would be used without debugger connected the whole program has to hang. This problem relates only to GCC linking configuration.

I don't know anything about Eclipse, but to get GDB to flash your chip you need to send it the 'load' command. I didn't see load anywhere in your settings so I'm assuming that is the missing piece.

Hello.

I took at look at your blog and I was able to get your examples to work. Thanks. I need to go through those more but I was able to get my code to work as well.

I found that in the Properties for my project, under C/C++ Build-> Settings and then under the Tool Settings tabs -> Cross ARM C Linker - Miscellaneous-> Other flags I had the following: --specs=rdimon.specs -Wl,--start-group -lgcc -lc -lc -lm -lrdimon -Wl,--end-group

I removed the --specs=rdimon.specs and I found that I could load my code and disconnect the debugger and when applying power the device would run.

In the readme.txt file of GNU Tools ARM, I found the following:

Users can choose to use or not use semihosting by following instructions. ** semihosting If you need semihosting, linking like: $ arm-none-eabi-gcc --specs=rdimon.specs $(OTHER_LINK_OPTIONS)

** non-semihosting/retarget If you are using retarget, linking like: $ arm-none-eabi-gcc --specs=nosys.specs $(OTHER_LINK_OPTIONS)

Upon changing my code to --specs=nonsys.specs or removing that from my linker flags, I was able to then load my debug code and have the device run when power was applied.

I hope this can help others if they have problems with getting a debug version working without the debugger attached.

Thanks.

Josh

Have a look at this blog. It's an Eclipse GCC setup. There are many examples code & projects you can use. It's hard tell what is the problem without knowing what you have in your project.
