Intel® Server System S7000FC4UR HSC Firmware Update
Revision 1.0
311
31.1.5 Set Program Segment Command
This command sets the upper 16 bits of the address for the Firmware Read, Firmware Program,
and Get Firmware Range Checksum commands.
31.1.6 FLASH Erase and Sequential Programming
There is no explicit erase command. Flash blocks are erased as needed when the Exit
Firmware Transfer Mode command is executed. Therefore, firmware updating proceeds
sequentially from the beginning of the operational code.
The HSC ignores all interfaces during a flash erase. Firmware transfer applications should have
their time-outs and retries designed accordingly. The worst-case flash erase time is one-half
second.
31.1.7 Access to Operational Mode Commands
Except for Get Device ID, non-firmware transfer network functions and their associated
responses are not recognized in firmware transfer mode. Firmware transfer ,ode must be exited
before issuing non-firmware transfer commands, such as application or event message
commands.
