Firmware Updates D-15
The LFU list command shows the current revision and update revision of
the SCM firmware. Note that LFU does not list each firmware file
associated with each micro that is listed in Table D–1. Instead, it lumps
them into one file, micro_fw. When using LFU, all microprocessor
firmware is updated each time LFU is run.
The LFU update command is issued.
Confirmation of the update is required.
SCM update and micro update begin.
SCMs are found at nodes E0 and E1. Updating the master and slave SCM
commences in parallel and completes.
Once the new SCM code is written into flash, the master SCM polls and
maps the entire CSB prior to LFU continuing and updating the other
micros in the system.
