Is it possible to locate start up code generated by PE in a defined memory location?
__thumb_startup() and its subroutines etc.
I was thinking along the lines of using "#pragma define section...", but can't find anything in CW10.5 for doing this.
I want to be able to control locations of certain routines for field upgrade purposes.
Thanks

I am using the LCF file too, like Alex wrote, in order to add section with specific address, then you can use this section in code with #pragma.
Look in freescale site for document about segmentation, and document about ELF linker.
If you still need detailed information let me know and I'll write a sample code with detailed information

I had used #pragma sections on other sections of code i wanted in specific locations, the problem with the PE-generated start-up code was that i had no editing control over it.
Took a while of throwing things at it to find this solution for the start-up code...
One observation from the freescale documentation was that it claimed you could place a named .c file in the structure above, but i got linker errors when trying this.
It only worked for .a files from PE, and .obj files from my code.
Since i was looking to place entire .c files into specific locations, it was much easier to name the files as "filename_c.obj" in the linker structure rather than adding #pragma section lines to the files themselves.
Cheers

Using this structure in my lcf file:
.startup :
{
librt_Thumb_LE_v7M.a (.text)
. = ALIGN (0x4);
} > m_startup
placed start up code in memory location of my choosing, by assigning a memory range to m_startup.
