Hi,
Three real-time libraries are created for our application from TI provided source files.
We need to know how to place those three libraries in a specific memory location in linker command file.
From where we can get information for this?
(The three libraries are Flash, Ram and Flash API).
Thanks,
Subha
Please see Allocate a Single Input Section from a Library, which is one part of the larger article Linker Command File Primer.
Thanks and regards,

Hi,
When I try to place my libraries, i got error like this,

Hi,
In TI provided Flash API library(F2838x_C28x_FlashAPI.lib), what does the below mentioned section in f2838x_flash_api_lnk.cmd file means?
GROUP
{
.TI.ramfunc
{ -l F2838x_C28x_FlashAPI.lib}
} LOAD = FLASH3,
RUN = RAMLS03,
LOAD_START(RamfuncsLoadStart),
LOAD_SIZE(RamfuncsLoadSize),
LOAD_END(RamfuncsLoadEnd),
RUN_START(RamfuncsRunStart),
RUN_SIZE(RamfuncsRunSize),
RUN_END(RamfuncsRunEnd),
ALIGN(8)
Thanks,
Subha
Diagnostics like these ...

... are usually caused by supplying two linker command files as input to the linker. Please carefully check the invocation of the linker and see if this is happening. If it is, then remove one of the linker command files.

I don't see that linker command file in C2000Ware, so I don't know where it comes from.
This code ...
Subha R said:GROUP
{
.TI.ramfunc

... is unusual in a few respects. That is why I suspect it has been modified. All that said, here is what this code does.
It forms a GROUP with one output section in it. While that is is legal syntax, it doesn't do anything useful. The GROUP could be removed.
It forms an output section named .TI.ramfunc. It is made up of all the input sections from the library F2838x_C28x_FlashAPI.lib. It is a good guess that this library only contains code sections (named .text) and no data sections. This GROUP/section is allocated a load address in the FLASH3 memory range, and a run address in the RAMLS03 memory range. It is aligned on an 8 word boundary. The LOAD_START, LOAD_SIZE, etc. operators create symbols that are used to implement the code which copies the GROUP/section from flash to RAM.
Thanks and regards,

Hi,
When I tried placing our own created RTL files, why certain .obj files are missing placed in memory range.
Why is that happen so? Is there any way to place those object files also ?
We created RTL flash library with the below mentioned files
_lock.c,
args_main.c,
sqrt_f32.asm,
log_f32.asm,
logtable_f32.asm,
errno.c,
exit.c,
s_frexpf.c ,
atol.c, ctype.c,
u_div28.asm,
div_f32.asm,
boot28.asm,
ll_aox28.asm,
ll_cmp28.asm,
ll_div28.asm,
ll_mpy28.asm,
autoinit.c,
startup.c,
pre_init.c,
cpy_tbl.c,
fs_div28.asm.
While placing the library in RAM, only the below mentioned .obj files are placed,
fs_div28.obj (.text)
cpy_tbl.obj (.text:copy_in)
autoinit.obj (.text:run_cinit)
exit.obj (.text:exit)
autoinit.obj (.text:run_pinit)
autoinit.obj (.text:__TI_auto_init_template)
sqrt_f32.obj (.text)
args_main.obj (.text:_args_main)
boot28.obj (.text)
autoinit.obj (.text:run_binit)
_lock.obj (.data:_lock)
exit.obj (.data)
autoinit.obj (.text:__TI_auto_init:__TI_auto_init)
pre_init.obj (.text:_system_pre_init)
exit.obj (.text:abort)
_lock.obj (.text:_nop)
startup.obj (.text:_system_post_cinit)
Why others are missed and how to place all at one instant?
Thanks,
Subha
The linker brings in a file from an library only if it contains a function (or data) that is needed by the program. Consider for instance ...
Subha R said:s_frexpf.c
This RTS source file defines the function frexpf. It must be the case that your program never calls this function.
Thanks and regards,
