the program could not run to _c_int00

yong lin

my project is rtsc Flashbios based under ccsv4.1.2,my platfrom is ezdsp28335,i compiled ok,but when i download the .out program.it could not run to main.i debug find that it run to

.sect "codestart"
code_start:
    .if WD_DISABLE == 1
        LB wd_disable       ;Branch to watchdog disable code
    .else
        LB _c_int00         ;Branch to start of boot.asm in RTS library
    .endif

but it could not run to _c_int00 .i could see _c_int00 asm : all is ffff code.

          _c_int00:
0x304ADA:   FFFF        ITRAP1
0x304ADB:   FFFF        ITRAP1
0x304ADC:   FFFF        ITRAP1
0x304ADD:   FFFF        ITRAP1
0x304ADE:   FFFF        ITRAP1

Yong,

This question appears to be non-BIOS specific. In hopes of getting you a faster answer, I'm going to move this thread to the C28x forum.

Yong,

It looks like it cant find the _c_int00 routine. If you right click on the project, go to Properties, Is the proper RTS library(rts2800_ml.lib)selected under the CCS Build option?

thanks to vishal coelho,my link library is rts2800_fpu32.lib.which is linked in the map file.my Runtime Support Library setting is automatic.even i set rts2800_fpu32.lib manually.the problem is also exist.i suspect something wrong with the watchdog or the PIEVECT table . it could not run to _c_int00.always loop at

6F00 SB 0,UNC.

the problem is result all because of the assigned "runSegment " address :

Program.sectMap[".text"] = new Program.SectionSpec()
Program.sectMap[".text"].runSegment = "FLASH_ABCDEFGH";
Program.sectMap[".text"].loadSegment = "FLASH_ABCDEFGH";

i change it to :

Program.sectMap[".text"] = "FLASH_ABCDEFGH";

it is really ridiculous
