error: Proteus VSM & keil for ARM 7 with global variable

[suryakant]

proteus for lpc2138

Hi,

When i am writing any simple code just to set & clear any particular pin in keil for lpc2138 it works fine but as soon as i assigned any variable as global variable then proteus doesn't work only.....

I tried both options:

1. Directly specified hex file path in Proteus VSM.
2. From keil VSM debugging --Remote degugging


I dont know what exactly the problem is ...

Please help me for this

I am attaching details of my error
1. Directly assigned hex file.
Please see code

#include <LPC21xx.H> /* LPC21xx definitions */ 

void wait (void); 
int main (void) 
{ 
unsigned int k; 
IODIR1 = 0xFF0000; /* P1.16..23 defined as outputs */ 

while (1) 
{ /* Loop forever */ 
IOPIN1 = ~(IOPIN1 & 0XFFFF0000); ; 
for (k=0;k<=65530;k++); /* Turn off LED */ 
} 

}

Please see the diagram NO- 1.direct_hex_file in attached files

2. In this code, i am just making variable "K" as global variable

#include <LPC21xx.H> /* LPC21xx definitions */ 
void wait (void); 

unsigned int k; 

int main (void) 
{ 
IODIR1 = 0xFF0000; /* P1.16..23 defined as outputs */ 

while (1) 
{ /* Loop forever */ 
IOPIN1 = ~(IOPIN1 & 0XFFFF0000); ; 
for (k=0;k<=65530;k++); /* Turn off LED */ 
} 

}

see the attachement 2.remote-degug_global_variable

please ..........let me know where i am going wrong or what is the problem in setting
