Discussion Groups | Rabbit-Semi | coData Structure Trashed: Run time error
This is a group for folks designing and programming embedded systems using the Rabbit Semiconductor C-programmable microcontroller. Rabbit Semi is a spin-off from Z-World who makes a variety of embedded modules and tools. This group is not affiliated with either Rabbit or Z-World, but is a user forum for sharing ideas, asking questions, flaunting knowledge, and other typical user group stuff. The Rabbit is a powerful uC, supported by a full-featured C-compiler.
coData Structure Trashed: Run time error - swapnil bakare - Apr 8 17:01:03 2008
Hello,
First time, I am facing such issue in last 2 yrs. The code is working from
last 2 yrs fine ... Nothing new added. I am not getting Y the problem is
raised now ??
Code is something like this :
main()
{
loopinit();
while(1)
{
loophead();
costate
{
}
costate
{
status = function();
}
costate
{
}
}//end while
}
int function()
{
//do something
status2 = function2();
return 1;
}
int function2()
{
//storing the root data in xmem using root to xmem :root2xmem()
return 1; // at this point coData structure trashed Run time error
occures...
}
This was not happening previously. No variable/constant changed in the code.
What might be the cause?
What might be the solution to resolve this?

Swapnil

Did you update the compiler? I find the later versions are buggy on
costates.
The compiler needs to track stack usage. It often gets confused. Keep
function variables small or static.
Because of these problems, i have gone away from costates and use my
CoExec. It is simpler, faster and ANSI.

James Cameron wanted Chuck Norris to play the Terminator. However, upon reflection, he realized that would have turned his movie into a documentary, so he went with Arnold Schwarzenegger.

Hi Scott,
No, I have not changed compiler nor it's new installation. Using DC
8.61. Nothing has changed from working code, compiler, Rabbit board, PC.
Any suggestion !!!
