Hi,

Please see document:

This page describes how to implemment the bootloades using SPI flash:

http://tiexpressdsp.com/index.php/Flashing_the_C6747

But you can use most os the principles for NAND flash.

1) Make sure that when you are generating the AIS using the AISgen.exe described in the page that you choose NAND flash instead of spi flash.

2) For the NAND writer, after you install all the software according to the GSG, it will be at:

C:\C674x_dsp_1_00_00_10\REL_LSP_02_20_00_07\PSP_02_20_00_07\board_utilities\flash_writers\nand_writer\ccsv3.3

This program works for the NAND flash that is in the daughter card for the OMAP-L137/C6747. Please find the daughter card for the OMAP-L137/C6747 EVM with an LCD display at:

The schematics are already available at http://support.spectrumdigital.com/boards/dskda830 under DSKDA830 User Interface Board.
