ATCA-7490 Installation and Use (6806800U11F )
352
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 263 .
9.13.1 Boot Bank Sensor
The ATCA-7490 provides a Boot Bank Sensor, illustrating from which FPGA Bank the FPGA has
booted last. For details, see
Boot Bank Supervision Sensor on page 337 .
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 286 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.
