Part Number: C66XCODECS

Hello

i want to rearrange the order of .obj file among .text section of map file,

ex:

.init_array
* 0 ab000000 00000000 UNINITIALIZED

.text                    0                     00800000                    00061c20
                                                 00800000                    00001ca0               a.obj
                                                 00801ca0                    00001780               b.obj
                                                 00803420                    000015a0               c.obj
                                                 008049c0                    000015a0               d.obj

Assume , my .map file is generated in above way. I want to modify map .text section, so that i achieve .text in below mention way. 

.init_array 
* 0 ab000000 00000000 UNINITIALIZED

.text                    0                     00800000                    00061c20 
                                                 00800000                    00001ca0               c.obj
                                                 00801ca0                    00001780               b.obj
                                                 00803420                    000015a0               a.obj
                                                 008049c0                    000015a0               d.obj

    Hi Prudhvi,

    I've forwarded this to the codec experts. Their feedback should be posted here.

    To understand the answer, you first need the background you get by reading the first part of the wiki article Linker Command File Primer.  

    This SECTIONS directive entry does what you request ...

        .text
    {
        c.obj(.text)
        b.obj(.text)
        a.obj(.text)
        d.obj(.text)
        *(.text)
    } > MEMORY_RANGE_NAME_HERE

    This creates an output section named .text.  The first four .text input sections come from those named files, in that order.  The remaining input sections named .text come next.

    Thanks and regards,

    -George

    HI George,

    Thanks for your response, The solution you have given works fine if we build the project, but m not expecting that, I want the linker file changes to be unchanged though i rebuild the project.
    would you please give any solutions for this?

    Thanks and regards
