For interrupt operation of ARM9

M.H

Genius 5960 points

Ｈｉ．

Using the sample below, I am trying to place a interrupt to the core of the AMR9.

http://processors.wiki.ti.com/index.php/QuickStartOMAPL1x_rCSL

I'm going to put the interrupt processing using the. Asm files of the following three in this.

ARM9_initstack.asm

ARM9_intvecs.asm

ARM9_handler.asm

Please allowed to check for ARM9_intstack.asm.

I have the following description in the file.

;*  If using the RTS library from the TMS470 Code Generation Tools 4.6.3 or
;*  earlier, include this file (use function _init_stack as an entry point)
;*  to initialize the privileged mode stacks.

Description of this place, If you are using a version earlier than TMS470 Code Generation Tools 4.6.3, file ARM9_intstack.asm Although we need,

If you use a version later than TMS470 Code Generation Tools 4.6.3 is, We recognize the file ARM9_intstack.asm that's unnecessary, but why not have a problem?

I'm sorry, please tell me.

Hi Hamada,

If needed, you can use the "ARM9_initstack.asm" file for your project.

RTS stands for Run Time library which is enclosed with CGT (Code generation Tools ) package. RTS contatins the following.

ANSI/ISO C/C++ standard library
C I/O library
Low-level support functions that provide I/O to the host operating system
System startup routine, _c_int00

In the file (ARM9_initstack.asm) desription, they intended to say about the usage of this .asm file, when the RTS library is used. ( which comes along with the package "TMS470 Code Generation Tools 4.6.3 or
earlier") . If you use the RTS library from the latest version of Code generation tools, ( I am guessing ) they might have used a diffferent method or a different file to initilaize the stack instead of using this particular *.asm file. You can download the latest version of Code generation tools and verify the RTS library.

However, the apt forum to post this type of question is TI C/C++ Compiler forum.

If you are looking on more information like using the *.asm file/functions, please refer to documents like Assembly language tools userguide and compiler user guide.
