REQUEST DATA
Byte Data Field
1 Control ID:
00h = Firmware Hub (SPI Flash) Selection
9Dh = Boot Order Configuration
2 Control State for SPI Flash selection:
(These settings are stored in EEPROM and applied (to logic) each time the IPMI controller
detects power-on)
00h = Standard SPI boot flash is selected (default)
01h = Recovery SPI boot flash is selected
Please note that this selection may be forcibly overridden either by DIP-Switch (SW3 switch 2,
refer to the AM4120 User Guide, Table 4-2) or during a bootloader firmware update process.
In case of a failed boot process from the standard SPI NOR flash, the IPMI controller will
select the recovery SPI NOR flash and boot the board again. In case of a boot failure from the
recovery SPI NOR flash, the board locks up. Refer to chapter 8. U-Boot Failover Control.
Control State for Boot Order Configuration:
(These settings are stored in EEPROM and applied (to logic) each time the IPMI controller
detects power-on)
00h = No override, boot as usual (for all other values, refer to the U-Boot User Guide)
