gdb on armv6

[Manuel Stühn]

Hi list,

is there something special to consider when debugging applications on armv6(-hf)?

I'm using FreeBSD-Current on a Wandboard-QUAD. Unfortunately it is not possible
for me to step through even simple applications. The program gets executed until it 
exits even if i use the step command.

Example:
manuel at wandboard:~/devel/gdb % cat gdb-test.c

#include <stdio.h>
#include <stdlib.h>

int
main( int argc, char* argv[] )
{
    int value;

    for( value = 0; value < 10; value++ )
    {
        printf("value: %i\n", value );
    }

    return value;
}   

manuel at wandboard:~/devel/gdb % clang -Wall -Werror -g3 -O0 -o app gdb-test.c
manuel at wandboard:~/devel/gdb % gdb app

Program exited with code 012.

This exact behaviour can also be seen on my other boards like BBB or RPI-B.

Any hints?

Thanks in advance.
