Hello, I'm using IAR C/C++ Compiler for MSP430 5.10.1 (5.10.1.50144)
with the MSP430F2617 MCU.

I have a problem when using pointers:
when i try to debug the program with the following part of code, the debugger "hangs" (it takes a while till the iar changes to debug mode and then i don't have any option available accept 'stop debugging' "

the problematic part:
char pic0[2500], pic1[2500], *pic_rd, *pic_wrt;
pic_rd = pic0;
pic_wrt = pic1;
Click to expand...

however, when i'm using only one command:
char pic0[2500], pic1[2500], *pic_rd, *pic_wrt;
pic_rd = pic0;
Click to expand...
or
char pic0[2500], pic1[2500], *pic_rd, *pic_wrt;
pic_wrt = pic1;
Click to expand...

the debugger works fine.

what could be the reason?
 

Hi

Don't use large array size with IAR decrease size or use union to divide the array to a smaller size section's

All the best

Bobi
