Upgrading Firmware
This section describes the procedure to use when upgrading the firmware component 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.
This chapter contains the following subsections:
§
iRIS Executive Firmware File Naming Conventions
§
§
iRIS Automated Upgrade Procedure (Firmware)
§
iRIS Manual Upgrade Procedure (Firmware)
3.8.1
iRIS Executive Firmware File Naming Conventions
The iRIS firmware is available as a single file for downloading and flash upgrading using iLink. The upgrade file is in the
format:
iRIS270_x-y-z.bin where:
x-y-z is the firmware version:
x – Major version
y – Minor version
z – Build version
e.g. iRIS270_1-0-0.bin iRIS 270 Firmware, 1.0.0
The default repository for the firmware files in iLink is C:\ProgramData\iQuest\iLink3\Programs.
