------------------------------------------------------------------------------- Example: Flash Programmer (Source data in internal memory) Target: ADSP-213*** Date: July 20, 2004 Tools: VisualDSP++ 3.5 Hardware: ADSP-213*** EZ-KIT LITE ------------------------------------------------------------------------------- This hardware example will use the Parallel Port to take a data buffer or ldr file in internal memory and program it into the AMD 1Mx8 flash memory on the ADSP-213*** Ez-Kit-Lite. This example is intended for use with the AMD 1Mx8 flash that is included on the ADSP-213*** EZ-KIT-LITE, but could be easily ported to program another type or size of flash. The example has several subroutines that are of interest. The subroutines will: -FLASH_FILE_SIZE: - check to see that the buffer 'my_file' is not too large to fit in the 1Mx8 flash -FLASH_RESET: - issue the flash reset command -ERASE_FLASH_CHIP; - erase the entire flash and wait until the erase command is completed -SECTOR_ERASE: - calculate the number of sector needed to hold the data and erase accordingly (and verify erasure) -PROGRAM_FLASH: - program the flash with the data/code in my_file and check for write cmd completion after each byte -VERIFY_FLASH: - verify the contents of the flash with the values in 'my _file', The user has the ability to erase the entire flash before programming (ERASE_FLASH_CHIP) or to erase on a sector-by-sector basis, preserving previously programmed code in other sectors. ------------------------------------------------------------------------------- Instructions: BYTES The parallel port uses an 8-bit external width, but we're using a 16- bit data width, so to keep sense of the counts in terms of bytes-per-word, define BYTES as seen here: #define BYTES 2// 4 * 8bits = 32 bit logical data //or 2 * 8bits = 16 bit logical data //or 1 * 8bits = 8 bit logical data my_file: this is a DSP loader file generated using the Loader Utility in VisualDSP. By default, this project expects the loader file to be a 16- bit include format generated using the PROM option of the loader.
