TMS320F28069: how to config/setup custom bootloader

EVS,

This is how I would approach the problem:-

1) One CCS Project to develop bootloader and would reserve one flash sector for storing bootloader code.
2) One CCS Project for developing application code and you have to reserve other flash sectors for storing application code

Bootloader code contents:-

Refer to example code in the below path for reference:
<controlSUITE>\device_support\f2806x\v151\F2806x_examples_ccsv5\f28069_flash_kernel

1) Entry point for this bootloader code should be at 0x3F7FF6
2) Include rts library and cinit
3) Configure SYSCLK
4) Unlock
5) Initialize bootloader peripheral and bootloader code
6) Receive a KEY_VALUE and check the following:-
KEY_VALUE == SPECIFIC_VALUE, Erase existing application code and update application received from bootloader
KEY_VALUE != SPECIFIC_VALUE, continue to jump to start address (Referred as APP_START_ADDRESS) of application code

7) Before executing any flash algorithm make sure to (Flash Erase / Program), CSM needs to be unlocked.
8) Set Flash CPU scale factor

Application code contents:-

1) This is completely upto user
2) Include rts library and cinit (Optional: Allows you develop this code independently of bootloader code)
3) Make sure start address of application code matches with APP_START_ADDRESS in bootloader code.
