9.4.5 SoftLoad Errors

It is possible for errors to occur during the SoftLoad update. All command responses should be
checked to verify all issued commands were accepted. The SoftLoad status should also be mon-
itored in the SOFTLOADSTATUS log. Any status enum value greater than the ERROR status indic-
ates an error has occurred during the SoftLoad update. In the event of an error, the SoftLoad
update should be restarted by issuing a SOFTLOADRESET command or normal operation can be
restored by resetting the receiver.
In rare cases after a SoftLoad error, the boot code may not be able to determine which is the
latest firmware to be executed. To protect against this, SoftLoad does not erase the previous
valid firmware image from flash on the receiver. In such cases, the boot code will execute the
old image and raise the "Safe Mode" error (see RXSTATUS log). If that error is detected, simply
restart the SoftLoad process to reload the new firmware image and the error will be resolved.

9.5 Upgrading Using the AUTH Command

The AUTH command is used to upgrade to a new OEM7 receiver model with an authorization
code that enables (unlocks) model features. This command only functions with a valid auth-code
assigned by NovAtel Customer
The upgrade can be performed directly through the NovAtel Connect command line or from any
other communications program.
Refer to Format of Firmware Files on page 117 for details on updating versus upgrading.

9.5.1 Upgrade Procedure

1. Power up the OEM7 receiver and establish communications.
2. Issue the LOG VERSION command to verify the current model, firmware version and serial
number (refer to Authorization Code on page 116 for instructions on obtaining).
3. Issue the AUTH command, followed by the auth-code and model type (refer to Authorization
Code on page 116 for details on obtaining any auth-code). The syntax is as follows:
auth <your auth-code here>
where auth is a command that enables model upgrades and auth-code is the upgrade author-
ization code, expressed as follows:
XXXXXX,XXXXXX,XXXXXX,XXXXXX,XXXXXX,MODEL,EXPDATE
where:
Each X character is a case-insensitive ASCII character.
l
The MODEL string is a maximum of 15 characters long and represents the model
l
enabled by the auth-code.
The EXPDATE string is the auth-code's expiry date, in YYMMDD format
l
Example:
auth 7WBMBK,887CB6,K5J3FH,5DF5P2,42PW8G,D1SB0GTT0,121211
When the AUTH command is executed, the OEM7 receiver reboots. Issuing the LOG VERSION
command confirms the new upgrade model type and firmware version number.
