TN-29-16: Boot-from-NAND with the TI OMAP2420 Processor
Writing Binary Images to NAND Flash with Limited OST Tools
Writing Binary Images to NAND Flash with Limited OST Tools Support
Some versions of the OST Tools do not fully support Micron NAND Flash devices. In
these cases, it is necessary to develop an alternative method for loading the boot code
into the NAND Flash device. A workstation similar to the one shown in Figure 11 is
required. In addition, modified X-Loader and U-Boot software are required. Contact
your Micron representative for the modified software.
