__SP_END And __STACK_SIZE missing during linking

ND — Fri, 29 Sep 2006 00:19:49 GMT

Hi,

I have the MC52233 DEMO board and writing a small project to get used of the RTOS. Im using Codewarrior 6.3.

Everything compiles, but I get the following link error message:

Undefined : "__STACK_SIZE"

Referenced from "TK_NEWTASK" in osporttk.c

Anyone let me know how to fix this problem?

Many Thanks

Neil

Hello

Apparently the RTOS you are using is expected symbols __SP_END and __STACK_SIZE to be defined.

In order to be able to link the application you have to define them.

Usually you define these symbols in the linker command file.

For example:

__STACK_SIZE = 0x800;

__SP_END = 0x20008000 - __STACK_SIZE;

This is directly related to the way the RTOS expects the stack to be set up.

So I would recommend you to check with your RTOS provider, how he is expecting the symbol to be defined.

Hi Neil:

Do you fix the error by codewarrior6.3 can't compile the coldfire TCP/IP Lite?

Many Thanks!
