Configuring U-Boot to Boot from Flash
The blade provides two redundant boot flashes which contain the U-boot images and also
Linux kernel images. It also contains two redundant root file systems.
This section describes how to configure U-boot to boot a Linux kernel stored in the boot flash
and to mount the root file system in the user flash. The procedure uses the U-Boot script
flashboot, which has been predefined by Artesyn Embedded Technologies.
1.
Configure U-boot to boot from flash:
setenv bootcmd $flashboot
2. Depending on your system configuration, you may want to specify network
parameters as follows:
setenv ipaddr <IP address>
setenv serverip <IP address>
setenv netmask <netmask>
setenv gatewayip <IP address>
3.
Enter
saveenv
, and then enter
boot
.
5.4
Selecting the Boot Flashes
This configuration determines which flash the blade is to boot from on the next restart. You can
either boot through IPMI or through a U-Boot command.
Using IPMI - This option uses the System Boot Options feature. For more information, see
the ATCAF125: Control using IPMI Programmer’s Reference.
Using U-Boot command - Use
bootsel 0|1|switch
, where 0 selects boot flash 0, 1
selects boot flash 1 and switch selects the currently stand-by boot flash.
