where can I find the function "_start"

[chengxiaowei]

Hi all!

I'd like to know a simple question about the MQX RTOS Initialization.

At the end of  "boot" function , the code is as follow:

       /* Jump to the main process */

           jmp _start

  where can I find the definition of "_start' ? I have search all the file in the project, but failed.

The _start is part of standard library startup block. The library delivered with CodeWarrior.

You can also find the source code for that library, located in the cw dir somewhere. I took the source of the needed thumb code only and skipped the unnecessaryparts for my rtos project . Compiled with gcc in eclipse. Works like a charm.
