ReadMe.txt for the FlashBlink54 example program
---------------------------------------------

02/16/00  R. Heeschen, Texas Instruments, Inc.
This is adapted from the 5510 EVM blink application.


To build and burn the FlashBlink54 example program into the Flash Memory of
the 5510 EVM (assumes CCS v2.0 or later is installed):

1) The makefile FlashBlink.pjt assumes that CCS resides in directory
           C:\ti\
2) Create a folder (call it "flash") in the c:\ti\myprojects folder.
   If you installed elsewhere, create a folder within the myprojects folder
   in the location where you installed.

3) Locate the folder FlashBurn\FlashBlink\FlashBlink55\
   and copy its files
      FlashBlink.pjt          (CCS project file if using CCS v2.0)
      FlashBlink.c            (FlashBlink C code)
      FlashBlink.cmd          (CCS Linker command file)
      FlashBlinkhex.cmd       (Motorola Hex conversion command file)
   from the FlashBurn distribution medium to this new folder.

4) Run CCS and use the Project Menu to open the project "FlashBlink.pjt."
   CCS may tell you it cannot find library files.

   If you installed Code Composer Studio other than in
   C:\ti\, then you will have to provide paths to the three
   libraries:

       CCS v2.0
       --------
       rts55.lib     ( usually in C:\ti\c5500\cgtools\lib\ )
       evm5510.lib   ( usually in C:\ti\c5500\evm\target\lib\)
       drv55x.lib    ( usually in C:\ti\c5500\evm\target\lib\)

   
5) Build the project. This should create the FlashBlink.out file.

6) In a DOS window, change to the project directory and run the hex
   conversion utility:

      >cd c:\ti\myprojects\flash
      >hex55 FlashBlink_hex.cmd

   This runs the hex conversion utility (hex55.exe) with the options
   stated in the command file, FlashBlink_hex.cmd. 
   The hex conversion utility outputs a map file, FlashBlink.map,
   and a hex file, FlashBlink54.hex. The .hex file is the downloadable code.
   NOTE: You can put the above two commands into a batch file and
         invoke the batch file using the "System Command" field
         of a FlashBurn document. See the FlashBurn Application docs.

7) Now use the FlashBurn application to program the on-board flash memory.
   For the EVM5510, you'll get the best results if you leave CCS running
   for the download.
   See the help files and readme for the FlashBurn application for details.

8) After using the FlashBurn application to burn-in the FlashBlink
   program, you can boot the program from the Flash memory as follows:
   - Close the FlashBurn and CCS applications,
   - To boot from Flash, make sure that DipSwitch #2 is OFF, 3,4,8 are ON. 
   - Press the reset button on the board, or remove and
     reapply power to the board.
   You will see the LEDs blinking in sequence.
