Tool/software: Code Composer Studio
Dear TI team,
My C2000 device is F280049 ( 64 pin), I want to change boot mode when I use CCS9.1 LED sample project.
My step as below:
1. modify "f28004x_codestartbranch.asm" ======================>
***********************************************************************
* Function: codestart section
*
* Description: Branch to code starting point
***********************************************************************
.sect "codestart"
.sect "OTP_KEY" ; add by me
.int 0x5AFF ; add by me
.sect "OTP_BMODE" ; add by me
.int 0xFFFF ; add by me
.sect "OTP_Boot" ; add by me
.int 0xFF03 ; add by me
code_start:
//======================================
2. modify "28004x_generic_flash_lnk.cmd"
MEMORY
{
PAGE 0 :
/* BEGIN is used for the "boot to Flash" bootloader mode */
BEGIN : origin = 0x080000, length = 0x000002

3. Build project and connect to debug mode -> program Flash -> and After program it will stop at as below screen.
4.Then I stop CCS debug mode & power off.
5.Power on, and program LED project sample code (original)
5. I found it can work for Zero Boot Mode Select , it always boot in to Flash mode (don't care GPIO24 or GPIO32 pin )
6. As my step 3 screen, is it correct ? and my step is correct? it need prgram Zero Boot Mode Select project then program application project?
