Re: Embedded program does not run correctly

Hi Graeme,
thanks much for your response.
This is our system:

CPU: MPC5200B
RAM: 64 MB = 32 MB RAM + 32 MB Filesystem
OS: Elinos glibc 2.3.4

We translated the mpatrol lib with debuginfo +
MP_BUILTINTSTACK_SUPPORT and note that mpatrol in the function
__mp_getframe (stackinfo * p) -> returnaddresses (p-> addrs, f,
MP_MAXSTACK (line 424) crashed. And if we translated mpatrol lib with
debuginfo without MP_BUILTINTSTACK_SUPPORT, we note that mpatrol in
signals.c: 82 static void signalhandler (int s, int c, struct
sigcontext * n, void * f) crashed. We could translated the lib with
debugging information and MP_LIBRARYSTACK_SUPPORT we get this log entry:
@(#) mpatrol 1.4.8 (02/01/08)

Hi, on our PowerPC we start our software with mpatrol, which creates a very big logfile (105 MB). The memory allocation grows to big (twice as big as usually)....

Hi Fahri, You don't have much physical memory on your chip, so you won't have very much available to your process after the operating system eats some of it ...
