Hi, I am using c51 keil compiler with cygnal chip c8051C020. I find problem in initilise static variable. exp. main() { static unsigned char i =0 ; i++; } when i write this type of code & simulate it ,i find that i is not initilise to 0. Note:this is just example code & not the actual program i work. If any specify me the reasion it will help me lot. Regards, Pandurang S.
If the external memory is configured before startup clear and ljmp ?C_START it will not be initialized. My experience is that if it is configured before startup clear and ljmp ?C_START it will be initialized. Also that would be the way the Keil software should work. Thus I see no other place that would affect the issue. Who knows (I refer to f12x for my knowledge) what SFR if the f020 could have a hidden effect re memory access. Erik
"If the external memory is configured before startup clear and ljmp ?C_START it will not be initialized." "My experience is that if it is configured before startup clear and ljmp ?C_START it will be initialized." Those statements appear to be in complete contradiction. What are you trying to say?
