TMS320F280049C: Boot from flash without using any GPIO

I want to boot from flash on power up without using any GPIO pins(f280049C).

Since this is an OTP modifications, I want to explicitly confirm these steps before making any changes(although there are many posts on this topic).

1. Confirm that linker command file has : BEGIN : origin = 0x080000, length = 0x000002

2. In file f28004x_dcsm_z1otp.asm:

            Modify Z1-OT-BOOTPIN-CONFIG by changing the  line:

                  .long 0x5AFFFFFF ;Z1OTP_BOOTPIN_CONFIG 

3. In the same file, modify Z1-OTP-BOOTDEF-LOW by changing the line:

                   .long 0xFFFFFF03 ;Z1OTP_BOOTDEF_LOW

Please confirm.
