Flash Memory Programming, Integrity, And Security - Texas Instruments UCD3138 Technical Reference Manual

Flash Memory Programming, Integrity, and Security

The UCD3138 offers flash security and a ROM based PMBus bootstrap program for flash programming
and program debugging.
It offers the choice between startup into the bootstrap program and startup into the customer program.
This section shows how to make best use of these features. It describes how to enable flash security only
when desired, and how to make "back doors" to permit reprogramming of devices with flash security
enabled.
This section starts with a quick start summary which gives a recipe for best practices for firmware
development and for production.
Next, it provides a detailed view of the UCD3138 Flash programming hardware and Boot ROM as a
starting point. Finally, it goes into detail with code examples for the exact procedures for Flash
management for firmware development and for production.
Chapter 16 goes into more detail on the mechanics of programming Flash while also executing from
Flash. Chapter 13
