Update OS image
The OS inside the H-32 can be updated. The H-32 supports three different ways of
updating an OS image.
Update by RESCUE DISK
Update by NAND IMAGE
Update by UPDATE OS IMAGE
A new OS can be downloaded from the
www.opticon.com
website. A particular update
image contains all the files needed to handle the described update procedures. A fully
charged battery is needed to do an update. When doing an update the H-32 can be
connected to power source to prevent H-32 to go low power mode.
8.1
Update by RESCUE DISK
Update by rescue disk will do a complete update and clear all data and registry settings
from the NAND inside the H-32. After doing an update this way the H-32 will be back to
factory default.
To start the update a bootable micro SD card is needed. The maximum size of the micro
SD card is 2GB.
Place the micro SD card in the PC and copy the content of the
RESCUE DISK
folder to the
root of the micro SD card. After the copy has completed put the micro SD card in the
micro SD card slot in the H-32. Put in the battery and boot the H-32. The OS update will
start automatically. Update is complete when the LED indicators turn green and a
message on the LCD display will indicate that update has completed.
Remove the micro SD card from the H-32 and boot the H-32 to start.
8.2
Update by NAND IMAGE
Update by nand image will update the OS image. Doing an update this way will preserve
data in H-32. It is likely that the registry will be cleared after doing update by nand
image. Updates have been tested with micro SDHC card up to 16GB.
Place the micro SD card in the PC and copy the content of the
NAND IMAGE
folder to the
root of the micro SD card. After the copy has completed put the micro SD card in the
micro SD card slot in the H-32. Put in the battery and boot the H-32. Press keypad key
[3] until the Opticon logo appears on the display. Release the key and press the center
trigger button to start the OS update. Wait until the update has completed message
appears on the LCD display.
Reboot the H-32 to have the H-32 run the new OS.
8.3
Update by UPDATE OS IMAGE
Update the OS by the update OS image way is the easiest and the preferred way of
updating the H-32 OS image. Updating an OS image this way can preserve registry
setting and data. There are some advanced command line options available.
