For interrupt operation of ARM9

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.

Best Regards,
