TN-29-16: Boot-from-NAND with the TI OMAP2420 Processor
Writing Binary Images to NAND Flash with Limited OST Tools
Write the U-Boot to the NAND Flash
1. Place the U-Boot file in the TFTP server.
2. Write a copy of the U-Boot file to the DRAM using the U-Boot program.
3. Erase the area in the NAND Flash where U-Boot will reside.
4. Copy the U-Boot program from the DRAM to the NAND Flash.
This step is illustrated in Figure 14.
