* user can load the image into ram via TFTP
** there's also a serial load option (using kermit or ymodem protocol) but we'll take care of this (primary due its slowness). Anyway, you can refer to [[Recovery U-Boot Image (Naon)]] again, which uses the serial port to download the 2nd stage U-Boot binary.
{{WarningMessage|text=Please note that loading the wrong U-Boot (1st or 2nd stage) image may damage the hardware permanently. Also a power interruption during the U-Boot update process may not allow the board to boot correctly. In this case user can refer to [[Recovery U-Boot Image (Naon)]] procedure for recovery}}
{{ImportantMessage|text=Please note that U-Boot 1st stage does NOT have networking support, due size constraint. For this reason, a corruption of the 2nd stage will allow 1st stage boot but will not allow loading 2nd stage via TFTP. Again please refer to the [[Recovery U-Boot Image (Naon)|recovery procedure]] for more details}}
{{Board Specific Information|text=Before continue reading, we suggest to first have a look at [[Memory organization (Naon)|Naon Memory organization]], where details of memory addresses and size are detailed.}}
