3.5 Procedure to Flash and Boot the LCDK

The NAND may be flashed either through the USB-serial port or through CCS. The software provided in the following application note provides both tools.

The following AISgen config file has the correct settings for NAND16 boot, with the CPU running at 300 MHz, and DDR2 at 150 MHz.

• LCDK AISgen Config
• Serial Port Method

1. Determine what serial port is assigned to the on-board UART->USB IC as show in Section 3.1.4.
2. Set the boot pins to UART2 boot mode as shown in Section 3.1.
3. Perform the following actions, where "COMx" refers to the COM port found in the previous step (COM8). For C6748 boards, replace "OMAPL138_LCDK" with "C6748_LCDK".
   1. Erase the entire NAND (optional):
   sfh_OMAP-L138.exe -targettype OMAPL138_LCDK -flashtype NAND -p COMx -erase
   2. Flash bootable AIS image (ais_image.bin) to block 1 of the NAND
   sfh_OMAP-L138.exe -targettype OMAPL138_LCDK -flashtype NAND -p COMx -flash_noubl ais_image.bin

   Run the commands and then power cycle or reset the board to initiate the process.

   3. CCS Method
4. SD/MMC Flashing
   1. Connect to the Arm or DSP with the GEL file loaded, which auto-initializes the DDR.
   2. Open (CCS3) or import (CCS4, CCS5) the NANDWriter_ARM or the NANDWriter_DSP project.
   3. Modify the #define "NANDWIDTH_8" to "#define NANDWIDTH_16" in nandwriter.c.
   4. Rebuild and run the code.
