Procedure to Flash NAND on Beagle Board

Flashing automatically while u-boot boots(using bootcmd feature)

• Format MMC/SD card as mentioned in Beagle Hardware Setup
• Save x-load.bin.ift to be flashed onto NAND as x-load.bin.ift on MMC
• Save MLO for MMC booting as MLO on MMC
• Save u-boot.bin to boot as u-boot.bin on MMC
• Save u-boot to flash as flash-uboot.bin on MMC
• Setup the Beagle Board to boot over MMC
• When Beagle boots it automatically flashes u-boot and x-loader onto NAND flash

NOTE: If NAND was flashed already then it might not automatically run the bootcmd. Erase the flash using NAND Command

      OMAP3 beagleboard.org # nand unlock
     OMAP3 beagleboard.org # nand erase

Then repeat the procedure

Flashing commands with u-boot

• Format MMC/SD card as mentioned in
• Save x-load.bin.ift to be flashed onto NAND as x-load.bin.ift on MMC
• Save MLO for MMC booting as MLO on MMC
• Save u-boot.bin to boot as u-boot.bin on MMC
• Save u-boot to flash as flash-uboot.bin on MMC
• Setup the Beagle Board to boot over MMC
• On u-boot prompt execute the following commands

         OMAP3 beagleboard.org # mmcinit
        OMAP3 beagleboard.org # fatload mmc 0 0x80200000 x-load.bin.ift
        OMAP3 beagleboard.org # nand unlock
        OMAP3 beagleboard.org # nand ecc hw
        OMAP3 beagleboard.org # nand erase 0 80000
        OMAP3 beagleboard.org # nand write.i 0x80200000 0 80000
        OMAP3 beagleboard.org # fatload mmc 0 0x80200000 flash-uboot.bin
        OMAP3 beagleboard.org # nand unlock
        OMAP3 beagleboard.org # nand ecc sw
        OMAP3 beagleboard.org # nand erase 80000 160000
        OMAP3 beagleboard.org # nand write.i 0x80200000 80000 160000

Flashing commands with uImage

To flash the uImage
OMAP3 beagleboard.org # mmcinit
OMAP3 beagleboard.org # fatload mmc 0 0x80300000 uImage
OMAP3 beagleboard.org # nand unlock
OMAP3 beagleboard.org # nand ecc sw
OMAP3 beagleboard.org # nand erase 280000 47FFFF
OMAP3 beagleboard.org # nand write.i 0x80300000 280000 1FFFFF

To read the uImage back to RAM and boot
OMAP3 beagleboard.org # nand read.i 0x80300000 0x280000 0x1FFFFF
OMAP3 beagleboard.org # bootm 0x80300000
