ADI 公司的DSP ADSP21262 EZ-KIT LITE开发板的全部源代码

-------------------------------------------------------------------------------
Example: PP Flash Programmer
Target: ADSP-21262
Date: September 19, 2003
Tools: VisualDSP++ 3.0 SP1
Hardware: ADSP-21262 EZ-KIT LITE
-------------------------------------------------------------------------------
This project provides C code capable of programming the entire AMD Am29LV081B
Flash that is included with the ADSP-21262 Ez-kit Lite.

This code provides a callable subroutine that can be used to program the flash
from a buffer in external memory.

The included main routine will program a buffer to the flash using this
subroutine.

-------------------------------------------------------------------------------
Instructions: To change the file to be programmed to the flash, simply add your file
to the project directory, change the name of the file to be included in main.c, and
update the main.c definition FILE_DATA_WIDTH to reflect the width of the file. Note
that the Symbol Manager does not provide the correct byte address of any buffer that
does not occupy the first address of a section defined in the LDF file. Either make
separate sections for each buffer to program, or manually resolve the location in the
LDF. It is also possible to do a simple calculation to get the correct address,
multiplying the address by the width of the device relative to 32-bits (after masking
the address decoder range.

By default, this project expects the input file to be a 16-bit include format 
generated using the PROM option of the loader. Also, non-boot data must be in 
16-bit include format.
