What is correct bootloader.bin source file ?

Hi everyone.

What is serial boot loader correct bootloader.bin file source?

I am working in serial flash update, I have a probleam.

I use with software update bootcode with sw01248-495.zip,
but not work with sflash.exe file.

Only work with Serial 'Flash Loader.zip' file containing bootloader.bin file.
But Serial Flash Loader.zip file not containing source code.
Flash Loader.zip file only contains binary bootload.bin, sflash.exe (2 files).


Is sflash.exe working with
sw01242-497.zip source compiled bootloader?
I tested it, do not working.

Is there any compile options?
for example boot_loader.h file's options.



I am working with LM3S6965 Evaluation board,
which I atached uart0 RS-232 port for this test.
Driver Library (1973) example
Hello program.
Compiler with Keil.



1) Well working with bootcode 'bootloader.bin' file

Where can I get bootloader.bin source code?
bootload.bin file size is 1,700kbyte
