ADI 公司的DSP ADSP21369 EZ-KIT LITE开发板的全部源代码

-------------------------------------------------------------------------------
Example: AMD Flash Programmer
Target: ADSP-21369
Date: July 10, 2005
Tools: VisualDSP++ 4.0
Hardware: ADSP-21369 EZ-KIT LITE
-------------------------------------------------------------------------------
This project provides assembly code capable of programming the entire
Parallel Flash that is included with the ADSP-21369 Ez-kit Lite.

The code illustrates the method used to access the on-board Parallel Flash which is
connected to the External Port. This code sets the AMICTL to Bus width of 8
with Packing disabled so that it could access each physical address of the
flash rather than the logical address for correct programming. Due to the command
formatting of the AMD flash it requires physical 8-bit space addressing rather than the
logical 32-bit space addressing (each address addresses four physical 8-bit spaces).

Source Files contained in this directory:

AMD Parallel Flash Programmer for 21369.asm - This is the main program that setsup the flash
FlashErased.asm - Checks whether the flash is erased
Flashreset.asm  - resets the flash
ProgramFlash.asm - Programs the flash
Readflashword.asm - reads a word from flash and stores in internal memory
SectorErase.asm  - Erases the flash sector by sector
VerifyFlash.asm  - Verifies whether the flash is programmed right or not
Write flash byte.asm - Writes data to the flash
21369_IVT.asm - Interrupt Vector Table
ADSP-21369-EZKIT.LDF - Linker Description File
Ezkit.ldr - Loader file generated from the EZKit Push Button Example

-------------------------------------------------------------------------------
Instructions: To change the file to be programmed to the flash, simply add your file
to the project directory and change the name of the file to be included in the
my_file array present in the AMD Parallel Flash programmer  file. By default,
this project expects the input file to be generated
by the Loader Utility provided by VisualDSP. The format that is expected is
 -Width: 16
 -Boot Type: Parallel Port (prom)
 -Format:    Include
