How to create library files on TMS570?

I did give it a try with a sample project, but do not see any issue that you are trying to report.

Do you have the following line in your sys_link.cmd ?

--retain="*(.intvecs)"

I'm still not very sure if this is the issue, but pls give it a try.

Hello, Sir

Thank you for your quick answer.

Yes. we found "--retain="*(.intvecs)" in sys_link.cmd file.

We'd appriciate if you check our project.

I attatched files below. (including compile log "log.txt")

1830.CCS_Proj.zip

For making library:  TMS570LS31USB_Lab0_make_LIB

For executing program with the generated library: TMS570LS31USB_Lab0_exec_LIB

We tried to change CCS version from 5.5 to 6.0, the situation don't change.

We were wondering if you could tell us the difference from your successful case.

Best regards

HI Matusan,

I downloaded your lib project, and built/compiled on my CCS (6.0). I don't see any error. My compiler is TI 5.1.6

Hello,Sir

Thank you for your quick action.

I understand any error is occured on your CCS.

We identified the fail by checking  "intvecs" word in the xxx.map file.  

Could you send us "TMS570LS31USB_Lab0_exec_LIB.map" file after built on your CCS environment? 

We'd like to know the  "intvecs" word on the file.

Best regards

Hi Matusan,

For Library project, it does not generate memory map file.

Hello, Sir

Thank you for your quick reply.

I understand what you mean.

Actually, for Library project, it does not generate memory map file.

Could you send us "TMS570LS31USB_Lab0_exec_LIB.map" file generated on the execution project as below.

Project name is "TMS570LS31USB_Lab0_exec_LIB"

My attached zip file contains two projects.  (For making library & For executing application by using generated lib )

If you execute to build on the "TMS570LS31USB_Lab0_exec_LIB project, TMS570LS31USB_Lab0_exec_LIB.map file is generated in "Debug" directory under the  "TMS570LS31USB_Lab0_exec_LIB project workspace.

Best regards

Hello,Sir

Thank you for your help.

Now, our customer is waiting the answer.

I would appreciate it if you could inform us about the current status.

Sincerely

Hi Matusan,

To map interrupt routines to interrupt vectors you need to include a intvecs.asm file. This file will contain
assembly language directives that can be used to set up the ARM's interrupt vectors with branches to your
interrupt routines. 

The linker will use intvecs.asm with the compiler's linker control file (*.cmd). The control file contains a SECTIONS directive that maps the .intvecs section into the memory locations 0x00-0x20.

In Project Property -- General, select "TMS570LS31xFlashLnk.cmd" in "Linker Command File:". This will generate a map file for you after "Build Project"

Dear QJ Wang

i have the same problem.

There are 2 ccs project, one produces the library (lib) and another to produce executable (out/bin) including library.

We already know that if you include asm file in the ccs project that produces the executable, all is okay (intvecs present in the map file at 0x00-0x20). Okay. 

Next step is to put the asm file in a ccs library project (lib). Than include the library (lib) in the executable ccs project (out/bin). In this case, the linker had not put the intvect in the expected place (0x00-0x020). I think it is mapped in the library code.

Then, how we can make visible the intvecs section to the linker in the ccs exe project

Note that in all the cases the link.cmd file has your suggested informations as following

---------------------------------------

--retain="*(.intvecs)"

MEMORY
{
VECTORS (X) : origin=0x00020000 length=0x00000020
//FLASH_API (RX) : origin=0x00020020 length=0x000014E0
FLASH0 (RX) : origin=0x00020020 length=0x002FEB00 //LS31x and RM48 Flash size is 0x300000
SRAM (RW) : origin=0x08002000 length=0x0002D000
STACK (RW) : origin=0x08000000 length=0x00002000
}
SECTIONS
{
.intvecs : {} > VECTORS

.text > FLASH0
.const > FLASH0
.cinit > FLASH0
.pinit > FLASH0
.data > SRAM
.bss > SRAM
}

-----------------------------------

I started this E2E thread.

And our problem has been solved.

Maybe I can show some clue for you. 

In our case, the point is "need two retain statements" as shown blow.

--retain="*(.intvecs)"

--retain=TMS570LS31USB_Lab0_make_LIB.lib<sys_intvecs.obj>(.intvecs) 

Please refer the bottom of page 197 in ARM Assembly Language Tools v5.1 User's Guide

I hope that this information(our case) will be of help to you.

Best regards

Dear all 

tank you so much.

I ported your both suggested changes in link.cmd file of my existing project, but the intvecs section and/or sys_intvecs.obj didn't appeared in the map file. Besides, the memory range 0-20 is not present in map file.

I created a new project, make the same settings (vars, includes, libraries etc.) and the same link.cmd file as previous project and magically the intvecs appeared in the map file.

I have the impression that, sometimes, code composer acts on a project configuration different than that show me.

Thanks

Paolo
