Chapter 7 NovAtel Firmware and Software
7.6.4 SoftLoad Update Method
This section describes the sequence of commands that are issued to the receiver when updating
using a *.shex file.
The response for each command must be processed before sending the next command
so as to determine if the command was accepted or rejected, and to wait for the
receiver to complete the operation. Responses to SoftLoad commands are guaranteed to
be output from the receiver within a specific time, which varies by command. Refer to
specific SoftLoad command for more information on responses and the timeout values
for SoftLoad commands.
1. Open a connection to any port on the receiver (COM, USB or ICOM) with the input and output
INTERFACEMODE set to NOVATEL.
2. Request the SOFTLOADSTATUS log using the following command:
LOG SOFTLOADSTATUSA ONCHANGED
3. Initialize SoftLoad with a SOFTLOADRESET command. This command stops all tracking on
the receiver to ensure sufficient memory is available for the loading process. An
RXSTATUSEVENTA log reports a SoftLoad In Progress status.
4. Open the *.shex firmware file.
5. Read each line of the *.shex firmware file.
a. Send S0, S5 and S7 S-Records directly to the receiver using the SOFTLOADSREC com-
mand. The S-Record must be enclosed in quotation marks:
SOFTLOADSREC "<S-RECORD>"
Data within S0 records can also be sent to the receiver by converting them to
SOFTLOADSETUP commands. Refer to the SOFTLOADSETUP command for details on
how to convert from S0 S-Records to SOFTLOADSETUP commands.
b. S3 S-Records should be parsed and packaged into a SOFTLOADDATA command.
6. Send the SOFTLOADCOMMIT command after all data from the *.shex file has been trans-
ferred to the receiver. The SOFTLOADSTATUS log reports the status of the loading process.
Wait for a SOFTLOADSTATUS log to indicate the status is COMPLETE. The COMPLETE status or
an error is guaranteed to be output from the receiver within 300 seconds from the time the
SOFTLOADCOMMIT command was received by the receiver.
7. Send the auth code for the newly downloaded image using the AUTH command. This is only
required if there is not already a signature auth code on the receiver as signature auth codes
are maintained through a SoftLoad update. See Authorization Code on page 53 for details on
Auth Codes.
AUTH ADD_DOWNLOAD <AUTH CODE>
8. Reset the receiver using any of the following methods:
Enter the RESET command
l
Enter the FRESET command
l
Power-cycle the receiver
l
Once the receiver resets, the new version of firmware is active.
