Hello,my ARM-Linux board seems to be resistant against bus errors/misaligned data access or the compiler does some magic to prevent these ;-)
Yes, the kernel "fixes" the unaligned access.
It would help me, to debug a program, when my board would abort with an error message, so that I can isolate the bug. Does someone know, if there exists something like a Linux option do disable/enable data aborts?
Yes, if you want signals, do: echo 4 > /proc/cpu/alignment ... and your program should abort at any unaligned access. Daniël
