Re: [U-Boot] Instructions in TEXT section can not load data from other section

17 Mar 2010

      Thanks for your advise, I compile with -mrelocatable. If I remove this flag, Error is shown:
ERROR: Your compiler doesn't generate .fixup sections!
My host gcc is  gcc 4.1.2 20080704 (Red Hat 4.1.2-44),
I try different toolchain:
powerpc-unknown-linux-gnu-gcc  gcc version 4.4.3 (crosstool-NG-1.6.0)
ppc_82xx-gcc gcc version 4.2.2   from ELDK
powerpc-603-linux-gnu-gcc gcc version 4.1.0 from crosstool 0.43
The problem is still there    : (

Hi, everyone.
I have got a problem when I porting U-BOOT to my board
with MPC8247. My configuration file is based on the MPC8260ADS_config.
The problem is : The instruction in TEXT section can not load data in
other (DATA) sections. It seems there is a relocation to the data section .
For example:   If I use
for (init_fnc_ptr = init_sequence; *init_fnc_ptr; ++init_fnc_ptr) {
    if ((*init_fnc_ptr) () != 0) {
        hang ();
    }
}

I can't jump to functions in  init_sequence[]  ;
If I called functions such as    get_clocks()  in board_init_f  , it works fine.
So the code in board_init_f can not load address in init_sequence[] , because
init_sequence[]  is out of TEXT section.
The same thing happens with iop_conf_tab[][], and strings used by "puts".
Anyone there has the same problem? Or know the point? Pls help!
Yes, that is a relocation problem. Do you compile with -mrelocatable?
If so, you might have a broken toolchain that don't produce .fixups
