REQUEST DATA

Byte Data Field

1 Control ID:

00h = Firmware hub (SPI boot flash) selection

9Dh = Reserved

2 Control State for SPI boot 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 the DIP Switch SW2,

switch 2 (refer to the AM4140 User Guide, Table 4-1) or during a bootloader firmware update

process.

To be able to change the SPI boot flash selection via the Set Control State command,

the recovery SPI boot flash must not be previously selected, either via the DIP switch SW2,

switch 2, or via the “flsw” U-Boot command. In order to select the standard SPI boot flash via

the Set Control State command, the DIP switch SW2, switch 2, must be set to OFF

and the “flsw” U-Boot command must use the option “s”.

In case of a failed boot process from the standard SPI boot flash, the IPMI controller will

select the recovery SPI boot flash and boot the board again. In case of a boot failure from the

recovery SPI boot flash, the board locks up. Refer to Chapter 8, U-Boot Failover Control for

further information.
