9.14.2 Fail Protect Logic
Fail protect logic is a mechanism implementing automatic FPGA bank crisis recovery. It
observes the FPGA boot phase to swap the FPGA banks and to reload the FPGA in case the FPGA
firmware hangs accidentally.
Fail protect can be enabled or disabled at any time using an IPMI OEM command called Set/Get
Feature Configuration and parameter #224. For details, see
Set Feature Configuration on page
255 or BIOS setup menu.
During initial power on, the IPMC selects the FPGA bank stored in NVRAM and evaluates the
FPGA DONE signal. If the provided signal is not asserted, the IPMC selects the FPGA backup
bank and tries to load the FPGA again.
