5.Send each line of the *.SHEX file to the receiver in a SOFTLOADSREC command. The S-Records must be enclosed by quotation marks:

SOFTLOADSREC "<S-RECORD>"

To significantly decrease data transfer time, NovAtel recommends creating a batch file to automatically send each line of SOFTLOADSREC. Contact NovAtel Customer Support for assistance creating SoftLoad batch files.

6.Send the SOFTLOADCOMMIT command.

7.During the loading process, SOFTLOADSTATUSA logs report the load status. Wait for the SOFTLOADSTATUSA to indicate loading is COMPLETE.

Signature authorization codes are maintained internally by the receiver and do not need to be re-entered. Refer to Authorization Code on page 46 for details on obtaining any authorization code.

8.Reset the receiver by entering RESET, FRESET or power cycling.

9.Once the receiver resets, the new version of firmware is active.

The SoftLoad process can be cancelled safely at any time during the process using the RESET command.

6.4.1Working with S-Records

•Records beginning with S0, S5 and S7 should be passed to the receiver directly using the SOFTLOADSREC command. These records contain meta data about the firmware image.

•Records beginning with S3 form the actual firmware image and can be converted to SOFTLOADDATA binary commands. Aside from the header, each pair of characters forms the ASCII representation of binary byte. The format is as follows:

S3

LL AAAAAAAA

DDDDDDDD...DDDDDDDD

CC

 

 

 

Check Sum. One's compliment of all other bytes

Little Endian Data. These bytes are copied into the "data" field of the

SOFTLOADDATA command

4 - Byte Address. Set this as the value of "offset" in the SOFTLOADDATA command

Length.This is the hexadecimal number of character pairs to follow in the record. This value minus 4 bytes for the address and 1 byte for the check sum is copied into the "data length" field of the SOFTLOADDATA command

Header

•Multiple S3 records can be packaged into a single SOFTLOADDATA command as long as the data from one S3 record follows immediately after the previous record, up to a maximum of 4096 bytes of data. That is, the address must equal the previous address plus the previous data length. The "offset" field remains the address of the first S3 record and the "data" and "data length" are updated to include the new data.

•The shex file data may contain many gaps and jumps. For example, in most NovAtel shex files data for address 0x000_00000 is stored near the very end of the file.
