How FlashBurn Works
This is an explanation on how the FlashBurn utility works, and how the FlashBurn
Porting Kit is used to support custom flash configurations.
Code Composer Studio, FlashBurn, and the FBTC Program
The following
diagram shows how FlashBurn works together with Code
Composer Studio to program flash.
Key Points:
- FlashBurn uses Code Composer Studio for all
communication to the target hardware. This
requires a JTAG emulator or the on-board communication
present on the DSK boards.
- FlashBurn begins by downloading a small target
application called the FlashBurn Target Component (FBTC)
to the RAM on the target hardware. The FBTC
implements all of the capability to erase, program and
verify flash memory on the target.
- FlashBurn starts the FBTC program running on the
target hardware and begin communicating with it over the
JTAG connection.
- FlashBurn reads the flash image to be programmed
from a .hex file. The flash image is sent to
the running FBTC program over JTAG using Code Composer
Studio.
- The running FBTC program burns the flash image into
Flash memory.
Using the FlashBurn Porting Kit
The FlashBurn DSK product delivers flash programming
support a predefined set of TI DSK boards. In
order to support custom hardware with different Flash
devices or memory configurations, the FBTC program must be
modified using the FlashBurn Kit.
The FlashBurn Porting Kit consists of:
- Complete C source code for the FBTC programs that
implement flash programming on each of the DSKs
supported in the FlashBurn DSK product. This
gives running examples of FBTC programs for C54x, C55x,
C64x, C67x and OMAP 5912.
- A FlashBurn Programmers Reference that describes the
porting process.
The porting process normally consists of:
- Choosing an example FBTC program that closely
matches the desired hardware configuration .
- Modifying the FBTC program to correctly erase,
program and, verify the flash contents.
Persons performing the FBTC port should be familiar with:
- The DSP architecture and use of Code Composer Studio
to build and debug their custom FBTC program
- Board initialization, chip enables, and memory
configuration concerns specific to the new target
hardware
