Serial Number Handling
The
Cyclone LC
firmware implements the automatic serial number mechanism (see
). The same serial number files are used with the Cyclone Image
Creation Utility, and the same commands are used to specify the serial number file and initiate
serial number programming and incrementation. The serial number data structure is saved in the
SAP image. Once a “PS” command is carried out, a serial number is programmed into the target.
Only after all operations have been completed successfully does the Cyclone firmware
automatically increment the serial number and store it in the Cyclone’s flash for internal images (or
external CompactFlash for external SAP images).
The CS and PS commands are not present in the Cyclone Image Creation Utility until a valid
programming algorithm is specified.
To complement the Cyclone’s usage in production environments, the Cyclone supports multiple
serial number structures for each programming algorithm block. Each SAP image may contain
multiple programming algorithms for every memory module it needs to program, and each
programming algorithm block may contain multiple serial number structures. The SAP image
sequence below illustrates this briefly:
CM algorithm_file_1
SS object_code_1
EM
PM
VC
CS serial_file1.ser
PS
CS serial_file2.ser
PS
