X-Loader can be -signed by Texas Instruments IFT and installed to Nand flash to achieve -Nand booting. - - -Status: -======= - -The support for Texas Instruments H3 board (OMAP1710) has been implemented -and tested.

Configuration -depends on the combination of board and CPU type; all such information is -kept in a configuration file "include/configs/<board_name>.h". - -Example: For a H3 module, all configuration settings are in -"include/configs/omap1710h3.h". - -For all supported boards there are ready-to-use default -configurations available; just type "make <board_name>_config". - -Example: For a H3 module type: - - cd x-load - make omap1710h3_config - -After a board has been configured, type "make" to build it supposing the -needed cross tools are in your path. - - -Image Format: -============= - -X-Loader expects OS boot loader (e.g. U-Boot) in Nand flash using -JFFS2 style ECC. - - -Prepare Booting Nand Flash: -=========================== - -After you have built x-load.bin for your board, you need to do the -followings to get it into Nand flash: - -1. 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 - - - - - - - - - - - - - - - - - - - - - -
