Subject: [U-Boot-Users] Loading from NAND using 'nboot' Periodically Fails
 Where 'nand read' Succeeds

Before I jump in with the BDI and start debugging, has anyone else using
'nboot' and FIT images noticed that 'nboot' periodically fails where 'nand
read.i' of the SAME region of NAND succeeds?

    => echo $bootaddr
    800000
    => echo $boot0
    nboot ${bootaddr} 0 0 && setenv bootargs root=/dev/mtdblock9 && run
    addjffs2 addtty && bootm ${bootaddr}
    => run boot0

    Loading from NAND 64MiB 3,3V 8-bit, offset 0x0
    ** Bad FIT image format

    => nand read.i ${bootaddr} 0 400000

    NAND read: device 0 offset 0x0, size 0x400000

    Reading data from 0x3ffe00 -- 100% complete.
     4194304 bytes read: OK
    => setenv bootargs root=/dev/mtdblock9
    => run addjffs2 addtty
    => bootm ${bootaddr}
    ## Booting kernel from FIT Image at 00800000 ...
       Using 'config at 1' configuration

    Using Haleakala machine description
    Linux version 2.6.25-rc3-00951-g6514352-dirty (gerickson at ubuntu-fusion)
(gcc version 4.0.0 (DENX ELDK 4.1 4.0.0)) #2 Wed May 28 22:49:36 PDT 2008
    Zone PFN ranges:
      DMA             0 ->    65536
      Normal      65536 ->    65536
    Movable zone start PFN for each node
    early_node_map[1] active PFN ranges
    ...

This is using AMCC's Haleakala board with Samsung K9F1208U0B NAND, though I
suspect that doesn't make any difference since nand read.i works fine.
