INTRODUCTION

 This is the bootloader firmware for the DSPdap player project. 
 This firmware is used to bootload the main program from the CompactFlash card
 into the DSP. This need was arised because the size of the EEPROM was not sufficient
 to hold the main DSPdap program firmware. Hence it was decided to use a this
 smaller bootloader program in the EEPROM and load the main program from CompactFlash.

 It also makes updating the main firmware easier. It becomes simply a matter of copying
 the updated firmware into the CompactFlash card using windows explorer.

 You will need the dspdap-flash firmware to flash this bootloader into DSPdap's EEPROM.

FILES

 This release contains the following files

./README.txt			Project overview
./COPYRIGHT.TXT			Copyright information
./LICENSE.TXT			Licensing information (GPL)

./bootloader.pjt		Code Composer Studio Project file
./bootloader.cmd		Linker command file
./make_bootloader_bin.cmd	Batch file for creating the binary image of the firmware

./*.c, *.h, *.asm		Source files


===============================================================================
BUILDING

 You will need Code Composer Studio v2.0 or later to build this firmware

 Open the bootloader.pjt file in Code Composer Studio and build it. This should 
 generate the bootloader.out output file in the debug directory.

 Run the make_bootloader_bin.cmd batch file. This will generate dspdap-bootloader.bin.
 This is the firmware's binary image file that must be flashed into the EEPROM using
 dspdap-flash.

 NOTE:
 make_bootloader_bin.cmd requires the hex55.exe utility. This gets installed with
 Code Composer studio in <code composer path>\C5500\cgtools\bin
 Either add this path in the Windows PATH environment variable or copy the hex55.exe
 utility into this project's directory before running make_bootloader_bin.cmd


===============================================================================
USING

 Please refer to the programming procedure documentation at http://dspdap.sourceforge.net
 to know how to use this firmware.

 NOTE: The CompactFlash card must be formatted using FAT32 file system only. The bootloader
 cannot understand other file systems.
