dividing .text section

[ransh]

Hello,

diving text section is described in http://www.xilinx.com/support/answers/21639.html

But it handles some file1/2/3.o.text files.  

Does anyone knows how to create or divide such files in the SDK single project ? 

Thank you,

Ran

Look for object files in the Deb/Src folder of your application directory.

Hi sampatd,

Is there anywhere it is described in more details please ?
I don't understand what is ment in the above link.
in /dbg folder I find several files with .o and .d postfix. but the original .ld script search for .text file, not .o:
.text : {
*(.text)
*(.text.*)
*(.gnu.linkonce.t.*)
} > microblaze_i_bram_ctrl_0_microblaze_d_bram_ctrl_0

Can you please explain a bit more what should be done ?

Thank you very much,
Ran

Hi,

Refer to the snapshot to set -save-temps option in SDK. Once this is done, SDK generates the .o files of all the source files in Debug/src folder.

If you have file1.o, file2.o, and file3.0 and assume that you have three memories DDR, BRAM, and LMBRAM then you can create two more text sections .text1 and .text2. Your linker script can look as below
.text : {
./src/file1.o
} > LMBRAM

.text1 : {
./src/file2.o
} > DDR

.text2: {
./src/file3.o
} > BRAM

The above code will make sure that the text sections of the different object files are placed in the memories defined.

You must make sure that you have the .text section - this is required by default

Hi Hem,

Thanks very much for the details.

I just tried to set optimize levele, but strangely it jumps back to no optimization. 

What does it mean ?

Thanks ,

If you are using SDK, then -save-temps switch is not required. SDK saves the object files automatically.

Thanks,

But Why I can't change optimize level ?

Hi,

I try to divide the .o files but it keep saying that bram0 is larger even though there is no file inside (there is no aaaa* file!!) :

.text : {

} > microblaze_i_bram_ctrl_0_microblaze_d_bram_ctrl_0

.textXXX : {
CZ5C2010A_uBlaze_POD_Code/*.o
src/*.o
} > microblaze_i_bram_ctrl_0_microblaze_d_bram_ctrl_1

What am I doing wrong ?

Regards,

Ran
