Compiler/AM3358: How to set _c_int00 to address 0x80000000 using TI compiler

Part Number: AM3358
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI C/C++ Compiler

Hi,

I've ported a program from GCC to the TI compiler and have been unable to set _c_int00 to address 0x80000000. How is this done?

I've consulted all the manuals for the compiler, for XDC, searched the forums and the FAQ here:

processors.wiki.ti.com/.../Accessing_c_int00

On GCC the address was set in the *.CFG with the following code:

Program.sectMap[".c_int00"] = new Program.SectionSpec();
Program.sectMap[".c_int00"].loadAddress = 0x80000000;
Program.sectMap[".c_int00"].runAddress = 0x80000000;

Under the TI compiler, it adds a line to the linker script:

.c_int00: load > 0x80000000, run > 0x80000000

The end result is the same though - the linker assigns the wrong address as shown below in this fragment of the map file:

ENTRY POINT SYMBOL: "_c_int00"  address: 8518c020

I would greatly appreciate any suggestions as to how to resolve this issue.

The tools I am using are:

CCS 6.1.1.00022

TI Compiler v5.2.5

XDC Tools 3.31.0.24_core

SYS/BIOS 6.42.3.35

CPU is AM335x

I've attached a copy of the linker script and map file.

  • The symbol "_c_int00" and the section ".c_int00" are not necessarily related. You need to make sure that _c_int00 is the first address in section ".c_int00". Otherwise, you'll need to change the linker command file so that it refers to the section _c_int00 is actually in.
  • Thanks for your reply.

    It would appear that _c_int00 is inside .text - the linker lists it as:

    8518C020 boot.aea8f : boot.oea8f (.text)

    What would I need in the linker script or *.cfg to move this function to 0x80000000?
  • Try this:

    .c_int00 { boot.oea8f(.text) } : load > 0x80000000, run > 0x80000000

    This assumes that _c_int00 is at the first address of .text in boot.oea8f.

  • Thank you for your reply. I added the line you suggested and got the following errors:

    "configPkg/linker.cmd", line 135: error #10008-D: cannot find file "boot.oea8f"

    "configPkg/linker.cmd", line 135: error #10026-D: expecting output section, GROUP, or UNION instead of ":"

    }

    I noticed in the map file that '_c_int00' is listed under GLOBAL SYMBOLS. It isn't listed under ".text" in the SECTION ALLOCATION MAP even though the address falls within the range assigned to .text. Would this have a bearing on the issue?

    I've attached the map file, command file and boot.asm files:

  • It turns out that boot.oea8f is in an archive, so you need to specify it like so:

    .c_int00 { boot.aea8f<boot.oea8f>(.text) } : load > 0x80000000, run > 0x80000000

    Please carefully note the difference between the name of the archive and the name of the object file in the archive ('a' vs 'o')
