Use Texas Instruments IFT to sign x-load.bin. This results in a -signed image called x-load.bin.ift. -2. Use Texas Instruments FlashPrep to generate a .out file using -FlashWriterNand and specifying 0 as nand target address. -3. Use Texas instrumnets Code Composer Studio to run the .out file -which flashes x-load.bin.ift to Nand flash. - -Next you need to get your OS boot loader to Nand at the address your -X-Loader expects. For the H3 example, you can use U-Boot to flash U-Boot. -You can't use FlashWriterNand because it uses ROM code ECC style. - - -More Information -================ - -OMAP1710 NAND Booting Design Document has more information. - -Implemenation notes: -==================== -H3, H4 support NAND flash booting -2430sdp & 3430sdp support OneNAND booting - - - - - - - - - - - - - - - - - - - - - -

Use Texas Instruments IFT to sign x-load.bin. This results in a -signed image called x-load.bin.ift. -2. Use Texas Instruments FlashPrep to generate a .out file using -FlashWriterNand and specifying 0 as nand target address. -3. Use Texas instrumnets Code Composer Studio to run the .out file -which flashes x-load.bin.ift to Nand flash. - -Next you need to get your OS boot loader to Nand at the address your -X-Loader expects.
