TN-29-16: Boot-from-NAND with the TI OMAP2420 Processor
Writing Binary Images to NAND Flash with Limited OST Tools
Write the OS Kernel to the NAND Flash
1. Place the OS kernel file in the TFTP server.
2. Write a copy of the OS kernel file to the DRAM using the U-Boot program.
3. Erase the area in the NAND Flash where the OS kernel will reside.
4. Use the U-Boot program to copy the OS kernel from the DRAM to the NAND Flash.
This step is illustrated in Figure 15.
