Novatel OM-20000122 Updating or Upgrading Using the WinLoad Utility, Transferring Firmware Files

NovAtel Firmware and Software Chapter 5

The new download package includes a signed firmware file type that uses an extension designated as “.shex” (example OEM060200RN0000.shex), as well as the latest Winload utility and What’s New file containing firmware update change details.

Prior to firmware version OEM060200RN0000, authorization codes depended on the software model, the firmware version and the serial number of the receiver. The authorization code changed if any of the three items changed. This is no longer the case.

5.3Updating or Upgrading Using the WinLoad Utility

WinLoad is the simplest and most common way to update or upgrade a receiver.

5.3.1Transferring Firmware Files

To proceed with an update or possibly an upgrade, obtain the latest version of firmware by downloading the (OEM Version) for your product from www.novatel.com/support/firmware-downloads/.

Types of Firmware Files

•OEM Version - NovAtel Customer Service may generate and provide the required authorization code. Authorization codes are obtained by contacting support@novatel.com or at www.novatel.com/Support/.

The OEM version is named OEMXXXX.EXE, where XXXX is the firmware version.

For convenience, copy the update file to a GNSS sub-directory (for example, C:\GNSS\LOADER).

If the firmware update file is password protected, NovAtel Customer Support provides the required password. After copying the file to a computer, perform the following steps to extract the files:

Syntax: [filename] [password] (if required)

where filename is the name of the compressed file (but not including the .EXE extension) and password if the password is required for extraction.

Example: OEM060000RN0000.hex

In the above example, a window appears asking for a password. The self-extracting archive produces the following files:

winload.exe	WinLoad utility program
howto.txt	Instructions on how to use the WinLoad utility
whatsnew.rtf	Information on the changes made in the firmware since the last revision
x..x.hex	Firmware version upgrade file, where x..x defines the product name and release
	(e.g., OEM060000RN0000.hex)

The files are extracted to unzip/program files/NovAtel Inc/x.xxx Full Update Disk, where x.xxx is the firmware version.

NovAtel has an online video tutorial that explains firmware uploading at www.novatel.com/ support/videos.
