Ok i definitely need to read up on the sections properly i am confused about that.

What about the second part of my question concerning the stack frame? This i presume would be same even in non-embedded codes. So, when a stack frame is created in the background when a function call is made does the stack frame contain all the variables declared inside that function (except the static ones) or can i have the local function variables somewhere...

Well i have some experience in writing C programs but never thought about what happens between the time i run the compiler to the time i run the final executable. But now that i am shifting to embedded systems i feel i should know whats happening under the hood. Any good reference for this would be helpful. I am currently looking at ARM based systems.

Hi,

I have gone through a few posts on this topic in the forum and seem to get more confused.

I write a simple function in C which has local/automatic variables say a,b,c

Now from what i could gather from the forum posts is that the sections (data,code,stac k,heap etc) are not a part of the C standard.

So, suppose i decide to place my function in the bss segment.

Now during...
