16 Appendix F – Upgrading Firmware/Software
16.1 Overview
This section describes the procedure to use when upgrading the firmware/software components in an iRIS.
The upgrade procedure has been carried out many times without issue. However, because the
process does involve erasing and reprogramming of flash memory, it is important that a good,
securely connected power supply is provided to the iRIS throughout the upgrade process.
16.2 File Naming Conventions
16.2.1 iRIS Executive Firmware.
The “Firmware” in the iRIS is analogous to the operating system in a PC. It is the Firmware that contains all
the low level functions and library routines used by the Application Software.
The iRIS firmware is available as a single file for downloading and flash upgrading using iLink. The upgrade
file is in the format:
iRIS350_xxx.fls where:
xxx is the firmware version
e.g.
iRIS350_250.fls iRIS 350 Firmware, Version Vk/2.50
The default repository for the firmware files is the “Firmware” folder under iLink.
16.2.2 iRIS Application Software.
The “Application Software” in the iRIS is analogous to an application such as Word® on a PC. It is
the software that contains the general functionality of the iRIS. This comes in three sections or
“banks” (due to the memory configuration of the iRIS) but runs as it were one single program.
The common software upgrade files for Banks 1 and 3 are in the format:
iRIS350_xxxx_yyy_z.irs where:
xxxx is the wireless module type (GPRS, CDMA, 3G, No Modem)
yyy is the software version
z is the program bank that this file should be loaded into
e.g. iRIS350_GPRS_150_1.irs iRIS 350 Software, GPRS, Version 1.50, Bank 1
The file for Bank 2 can be different depending on the program variant. This means that the Bank 2 file
has an extra field in its name. The default variant name is “Std” for the standard issue software.
e.g. iRIS350_3G_Std_150_2.irs iRIS 350 Software, 3G, Standard, Version 1.50, Bank 2
The default repository for the program files is the “Programs” folder under iLink.
