C2510 IAR Idatastack error

Anyone?

Hello Hithesh,

Lets see if we can get you running your sample code in debug mode. First though, did you try to compile and run an unmodified example with debug without download?

In your Project -> Options, your Target will be CC2510

When I try a sample code from swrc133 and start debug without download, I can run(single step) the code but nothing happens in the registers.

See screenshot. The code changes IEN1 to 0x02, but I don't see any change in IEN2 register. After execution the content is still 0x00

greenja, thedevice is selected as cc2510F8. I also tried with F16 and 32. 

Change your setting to match the my target settings, except of course the device.

I made the changes. Changing Location of constants and strings to "ROM mapped as data", gives this error when I rebuild - 

"Fatal Error[Ta031]: Locating constants and strings in ROM memory, located in the data memory space, is not allowed when using data model tiny or small"

I changed back to RAM Memory. Rebuild is successful. But the idatastack error still exists.

You have to change the mode to large.

On the CC2510, banked xcl file is not available. So I cannot use Large Data model.

So I tried CC2530. Rebuilds successfully. But I still get the idatastack error.

I guess, the 8051 in CC devices are same?

Match this setting $TOOLKIT_DIR$\config\devices\Texas Instruments\ioCC2540F256.ddf with your device

Matched, but I still get the idatastack error.

You need to Download and Debug in Simulation Mode.

Hello Hitech, 

Just want to make sure you have set the following as greenja also mentioned:

BR. Eirik

Eirik, My settings are same as screenshot.

greenja, I checked that. 

My code doesn't doe anything. I have written a delay routing. But I don't see  the timer registers incrementing. 

Here's the code - 

#include<iocc2510.h>

void delay();

int main( void )
{
T1CTL=0X06; //Prescaler=32
T1CNTL=0X10;

while(1)
{
delay();
P2=0xFF;
delay();
P2=0x00;
}

}

void delay()
{
while(!T1IF);
T1IF=0;
T1CNTL=0X00;
T1CNTH=0X00;
}

Eirik, My settings are same as screenshot.

greenja, I checked download and debug. 

When I run, I can see the T1CTL and T1CNTL change. But nothing after that. I have written a delay routine. The timer should increment. But I don't see  the timer registers incrementing. 

Here's the code - 

#include<iocc2510.h>

void delay();

int main( void )
{
T1CTL=0X06; //Prescaler=32
T1CNTL=0X10;

while(1)
{
delay();
P2=0xFF;
delay();
P2=0x00;
}

}

void delay()
{
while(!T1IF);
T1IF=0;
T1CNTL=0X00;
T1CNTH=0X00; 
}

Hitesh,

As long as you don't have actual hardware to run on, and you only debug on the "simulator", it is expected that you don't see the registers change. We do not have a simulator for the CC2510 device (or any of our 8051-based devices), so the simulator can really only be used to verify algorithms and general program flow. All hardware interactions (e.g. registers and such) will not work as it would on a real device, though.

Another thing: You mentioned that you could not use large memory model for the CC2510. This is not true. The memory model tells the compiler where it can place variables. For large memory model, it will use the XDATA memory space (and not just the DATA/IDATA memory space) for variables/heap.
