FLASH memory range overlaps existing memory

yong lin

I am developping a rtsc project under ccsv4.1.2,my dsp/bios version is 6.31,my platform is control28335.The DSP2833x_CodeStartBranch.asm,DSP2833x_CSMPasswords.asm are in my project.My user cmd file is F28335_BIOS_flash.cmd.the content is as follow:

MEMORY
{
PAGE 0 :
   /* BEGIN is used for the "boot to SARAM" bootloader mode      */
   /* BOOT_RSVD is used by the boot ROM for stack.               */
   /* This section is only reserved to keep the BOOT ROM from    */
   /* corrupting this area during the debug process              */

   BEGIN_FLASH      : origin = 0x33fff6, length = 0x000002     /* Boot to M0 will go here                      */
   PASSWORDS    : origin = 0x33FFF8, length = 0x000008     /* Part of FLASHA. CSM password locations in FLASHA            */
   CSM_RSVD    :origin = 0x33ff80, length = 0x0076

PAGE 1 :

}

{

   codestart         : > BEGIN_FLASH,           PAGE = 0           /* Used by file CodeStartBranch.asm */
   csm_rsvd          : > CSM_RSVD,              PAGE = 0           /* Used by file passwords.asm */
    passwords         : > PASSWORDS,             PAGE = 0           /* Used by file Passwords.asm */
   ramfuncs    :   LOAD = FLASH, PAGE = 0           /* Used by file Flash.c */
                         RUN = L03SARAM,      PAGE = 0           /* Load to flash, run from CSM secure RAM */
                         LOAD_START(_ramfuncs_loadstart),
                         LOAD_SIZE(_ramfuncs_loadsize),
                         RUN_START(_ramfuncs_runstart)
}

when i compiled the project ,i always got the error:

error: FLASH memory range overlaps existing memory range CSM_RSVD...

error: FLASH memory range overlaps existing memory range BEGIN_FLASH...

how could i solve this problem?My debugger is xds510,which is now only support ccsv4.1.so i cann't change to ccsv4.2.

In the Memory definitions, how is FLASH defined? The error indicates that the start + length of FLASH overlaps the sections you show above.

thanks Lori.the automatically generated memory map xdl file from the template linkcmd.xdt is as following:

...

MEMORY
{
    PAGE 0: MSARAM : org = 0x0, len = 0x800
    PAGE 1: PIEVECT : org = 0xd00, len = 0x100
    PAGE 0: L03SARAM : org = 0x8000, len = 0x4000
    PAGE 0: L47SARAM : org = 0xc000, len = 0x4000
    PAGE 0: OTP : org = 0x380400, len = 0x400
    PAGE 0: FLASH : org = 0x300000, len = 0x40000
    PAGE 0: BOOTROM : org = 0x3fe000, len = 0x1fc0
}

...

    xdc.meta: load >> FLASH PAGE 0, type = COPY

    .vecs: load >> PIEVECT PAGE 1
    .econst: load >> FLASH PAGE 0
    .const: load > FLASH PAGE 0 START(const_start) SIZE(const_size)

}

I know the memory CSM_RSVD overlaps with the automatically generated memory FLASH .but i don't know how to modify the FLASH memory.when i try to click the Tools->RTSC Tools->Platform->Edit/View.there is nothing to happen.my platform is c28xx,someone said that ccsv4.1 doesn't support Platform->Edit/View with platform c28xx.so how can i solve the overlap problem.

should i try use xdc script?

var Platform = xdc.useModule('ti.platforms.control28335.Platform');

Yong,

I am going to move this thread to the BIOS forum. They are more familiar with this tool and perhaps can help.

Regards,

Lori

I solved the problem by building my own platform.http://www.eclipse.org/forums/index.php/t/199087/

will give you help.
