Hello!
I'm using a AT89c51RC Controller for my application.
When I define global variables with an initial value, they are not always initialized correctly.
Example:
signed int test=3;
If I place the variable on the beginning of the xdata memory space, then they are initialized correctly. But if I place the variable at the back of xdata, they have wrong values like -16235.
I have deleted or commented out all loops in my programm, so there cannot be a memory overflow, that is produced be me.
If I initialize the variables later within my program manually, everything works correctly -> so the error must occur before the program starts.
I also checked out the amount of xdata that is used by my program, but its far from being full.
Is it possible, that there is an error in the startup.a51 or init.a51 files?
I use no reentrant functions, so I disabled the XBPSTACK but that changed nothing ...
Maybe someone can help me or give me a hint
Josef
