Flashing¶

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

• using /usr/sbin/ubiupdatevol:
  

  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
  

• using /APP/dev_only/swupd.sh
  

  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
  

/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.
