SoftLoad Update Method

This section describes the sequence of commands that are issued to the receiver when updating using a
*.hex or *.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 the
for more information on responses, and the timeout values for SoftLoad commands.
1. Open a connection to any port on the receiver (COM, USB, ICOM or XCOM) with the input and out-
put INTERFACEMODE set to NOVATEL.
2. Request the SOFTLOADSTATUS log using the following command:
LOG SOFTLOADSTATUSA ONCHANGED
3. Initialize SoftLoad with a
receiver to ensure sufficient memory is available for the loading process. An RXSTATUSEVENTA log
reports a SoftLoad In Progress status.
4. Open the *.hex or *.shex firmware file.
5. Read each line of the *.hex or *.shex firmware file.

commands. Refer to the

6. Send the SOFTLOADCOMMIT command after all data from the *.hex or *.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
MIT command was received by the receiver.
7. Send the auth code for the newly downloaded image using the
if there is not already a signature auth code on the receiver as signature auth codes are maintained
through a SoftLoad update. See Section 7.2 on page 96 for details on Auth Codes.
