WARNING: (374) ORDER command could not be obeyed for section STACK

Does this help?:

"The linker is unable to allocate memory in the order specified for the section listed in the ORDER command. A possible example is:

ORDERsect1,sect2,sect3 SECT sect2=0

Since sect2 must begin at address 0, there is no way sect1 can precede it."

From "Assembler/Linker/Librarian Users guide and reference for the 68000 family".

Regards Richard.

Hi Richard, Yes, this is certainly a step in the right direction, thanyou.

I'll go look this up - I think I was looking in the wrong manuals!

Thanks, Alastair

Hi Richard, I have resolved this now - two things worked:

Re-order the sections (e.g. in the example above put sect2 before sect1). Or, in my case decrease the size of one section so that it does not overrun into the space of another section.

Thanks very much, Alastair

This means the linker cannot lay out all of your variables in the target's memory space, because there is not enough memory. Your makefile (or whatever build system you use) will be telling the linker how much space is available for static data, and you have just exceeded that limit so the linker is saying that it all won't fit.

If you look in the .map file generated and search for that warning message, you will see how much space it has and how much space you need.

To solve the problem, either use less static data, or change your device's memory layout (if that is possible of course -- plugging larger numbers into the linker without thought, will just mean that when you go and load the code to the device, it will try and use memory that either doesn't physically exist, or is in use by some other application or piece of hardware).

If you don't understand the memory layout of the device you are programming, it is certainly time to get in contact with the guys who actually make the device and designed the programming environment.

You should get a support contract with whatever vendor has supplied you the hardware and the development environment.

Also you could get a support contract with Microtec.

The compiler should have come with printed manuals (well, mine did anyway), although the Microtec linker manual is pretty sparse and doesn't answer many questions.

Heh heh... Yeah - NOW I know, I have just been getting loads of greif about this from other groups! - but thanks for the warning!

Yes, you are correct - I mad the amount of space used by the "heap" (dynamic storage) smaller in exchange for more static storage, and this fixed the problem.

I origionally thought this was a coding issue, so I didn't look in the Linker manual (I did check the compiler manual). Turns out there is some information in the linker manual.

Thanks for your help, Alastair
