TMS320F280049: Projects containing the same files with different build results

Part Number: TMS320F280049

Tool/software:

Hi Champs,

I ask this for customer.

There are two projects, project1 and project2 -- these two projects use exactly the same CCS version, exactly the same compiler, the exact same source files (.c, .cla, .h), the exact same cmd file, runs on the same computer.

The cmd file specifies that the allocation for FLASH_BANK0 is as follows:

   FLASH_BANK0_SEC1_2_3_4_5_6  : origin = 0x083040, length = 0x003FC0            /* on-chip Flash */

   FLASH_BANK0_SEC7_8_9_10  : origin = 0x087000, length = 0x005000    /* on-chip Flash */

   FLASH_BANK0_SEC11_12_13_14_15  : origin = 0x08C000, length = 0x004000     /* on-chip Flash */

.cinit : > FLASH_BANK0_SEC1_2_3_4_5_6 | FLASH_BANK0_SEC11_12_13_14_15, PAGE = 0, ALIGN(4)
.text : >> FLASH_BANK0_SEC7_8_9_10 | FLASH_BANK0_SEC1_2_3_4_5_6 | FLASH_BANK0_SEC11_12_13_14_15, PAGE = 0, ALIGN(4)

But Project1 builds successfully. Project2 failed, error message is as below:

"../28004x_cla_flash_lnk.cmd", line 119: error #10099-D: program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. placement with alignment/blocking fails for section ".cinit" size 0x339 page 0.  Available memory ranges:

   FLASH_BANK0_SEC1_2_3_4_5_6   size: 0x3fc0       unused: 0x2          max hole: 0x2      

   FLASH_BANK0_SEC11_12_13_14_15   size: 0x4000       unused: 0x33f        max hole: 0x33b    

error #10010: errors encountered during linking; "QT2_AC_side.out" not built

I asked the customer to compare the map files of the two projects, and it really did make a difference.

Project 1:

  FLASH_BANK0_SEC1_2_3_ 00083040   00003fc0  00003d39  00000287  RWIX

  FLASH_BANK0_SEC7_8_9_ 00087000   00005000  00005000  00000000  RWIX

  FLASH_BANK0_SEC11_12_ 0008c000   00004000  0000385f  000007a1  RWIX

Project 2:

  FLASH_BANK0_SEC1_2_3_ 00083040   00003fc0  00003fbe  00000002  RWIX

  FLASH_BANK0_SEC7_8_9_ 00087000   00005000  00005000  00000000  RWIX

  FLASH_BANK0_SEC11_12_ 0008c000   00004000  00003cc1  0000033f  RWIX

Project1 and project2 is the difference on which setting causes the allocation of FLASH_BANK0 to be different? How do I find it? Thanks!

    Julia,

    I'm re-assigning this to the SW tools team, they should be able to help out here.  Sorry for the delay in our reply.

    Best,
    Matthew

    For both builds please send the following:

    • The text (not a screenshot) of the link command, exactly as system sees it, i.e. with all the build variables replaced with their contents
    • Linker command file
    • Linker map file

    I cannot guarantee this information will allow me to determine the cause of the problem.  But it might.  I'm sure I'll be able to ask better questions.

    Thanks and regards,

    -George
