Optimux-108 Ver. 6.1 Performing Additional Tasks 4-23
Optimux-108 stores two software versions, each of them in one of the two 1.15
MB partitions of its flash memory, which also contains a boot program. The
software is stored in compressed format. The main version is decompressed and
loaded into the Optimux-108 RAM upon power-up. The backup software is kept
for backup purposes. If the main software becomes corrupted, you can swap it
with the backup. By default, Optimux-108 is delivered with active software only.
New software releases are distributed as *.img files, which are downloaded to
Optimux-108. When starting a download, Optimux-108 erases the current backup
and places the new software in the backup partition. When downloading is
complete, the unit checks the integrity of the new software file. If it is correct,
the backup and active files are swapped. The new software release becomes
active and the former active software becomes the backup. If a failure occurs
during downloading, the new version is erased. In this case, only one version is
left stored in the flash memory. The backup software can be downloaded to the
unit and swapped with the main software later.
Downloading software is performed using the TFTP or X-Modem protocols. The
software files can also be downloaded to Optimux-108 via Boot Manager, using
XMODEM or TFTP, as explained in
Appendix B .
