h1. Flashing

There are several way to flash partitions (e.g. updating) manually:

* using @/usr/sbin/ubiupdatevol@:

<pre>

ubiupdatevol version 1.2 - a tool to write data to UBI volumes.

Usage: ubiupdatevol <UBI volume node file name> [-t] [-s <size>] [-h] [-V] [--truncate]

			[--size=<size>] [--help] [--version] <image file>

Example 1: ubiupdatevol /dev/ubi0_1 fs.img - write file "fs.img" to UBI volume /dev/ubi0_1

Example 2: ubiupdatevol /dev/ubi0_1 -t - wipe out UBI volume /dev/ubi0_1

-t, --truncate             truncate volume (wipe it out)

-s, --size=<bytes>         bytes in input, if not reading from file

-h, --help                 print help message

-V, --version              print program version

</pre>

* using @/APP/dev_only/swupd.sh@

<pre>

swupd.sh - update flash partitions on the target

Easy mode:

   using NFS: swupd.sh -i<IP> -p<PATH>

   where:

   <IP>   = IP address of your VM (defaults to 192.168.16.18)

   <PATH> = path of NFS directory (defaults to /home/femto/ftpdata)

   using wget: swupd.sh -w<URL>

   where:

   <URL>  = URL to fetch images from (e.g. ftp://user:pass@host/path)

Expert mode: (stay away from them!)

   -k update kernel

   -r update root fs

   -a update application partition

   -u update unitdata partition

   -c update caldata partition

   -x toggle banks

   -z don't reboot after successful update

   -o<str> Pass option string <str> to wget

</pre>

@/etc/init.d/flash_update@ takes care of flashing all partitions at once (automatically).

Lastly the operator can also flash images remotely through @/APP/bin/oam_start@.
