The actual values for the stack etc look ok to me in the attached doc, unless I have missed something !

As your program is approx 40k I would recommend using -mods memory model (libis.st7 lib), then you can remove the shared memory section.

Datz,

a colleague suggested the problem is probably in the declaration in your first post

int *tx_buff=(UINT16 *)&dest;

that should probably be

int *tx_buff=(UINT16 *)dest;

With the extra ''&'' in your decalaration you take the address of dest instead of its value and then tx_buff points in the middle of the stack which leads to crashes.

Let me know if it works.

Regards,

Luca

Hi luca,

if you see the attached document you will see an anather example and the problem still exist.

my conclusions are:

since I have about 40K code,using about 2K RAM the only model witch is now work successfully is the (+modml) memory long as jatin recomended.

+mods is faild because the RAM size.

+modsl is faild in run-time bacuse the overlap.(cannot be used for any application).
