ATCA-7480 Installation and Use (6806800T17A) 319
The IPMI command Set/Get System Boot Options together with the parameter #96
can be used to specify the FPGA boot bank from which the payload shall boot persistently. For
details, see
System Boot Options Commands on page 233 .
9.13.1 Boot Bank Sensor
The ATCA-7480 provides a Boot Bank Sensor, illustrating from which FPGA Bank the FPGA has
booted last. For details, see
Boot Bank Supervision Sensor on page 304 .
9.13.2 Fail Protect Logic
Fail Protect 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 of 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 256 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.
