7.2 Loading Kernel and/or Flash Executive Files
[Tools][Advanced][Flash Executive]
These files are loaded as part of the manufacturing process and are unlikely to need to be reloaded by the
User. The facility to load replacement programs will enable firmware upgrades to be made without
returning the device to iQuest.
The general process of loading these flash executive files is the same as loading an application program.
Files to be loaded will be supplied by iQuest or may be available from the iQuest web site,
www.iquest.co.nz.
7.2.1 Loading a Kernel Program
The “Kernel” file in a device can be treated like the BIOS on a PC. Kernel files
should NEVER be loaded over any communications medium other than a clean
RS232 link with the User PC next to the device. Although a loss of
communications during a partial load will not render the device useless, it will
prime it to fail later if the device is de-powered or has a watchdog reset.
For the reason above, it is most important that communications is not lost to the device during the process
of loading the kernel file.
If the device loses power during the update process, it will need to be returned to iQuest for servicing.
