11.5 Serial Number Handling in Cyclone for ARM devices
The Cyclone for ARM devices’ firmware implements the automatic serial
number mechanism. 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 for
ARM devices firmware automatically increment the serial number and store it
in the Cyclone for ARM devices’ 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
for ARM devices 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
CS serial_file_3.ser
PS
CM algorithm_file_2
SS object_code_2
EM
