Preliminary

The multiboot method allows users to specify multiple boot methods to be tried in a 

given sequence. For example, the user can set “network with dhcp” as the first 

option to boot XLR, “network with static IP” as second option in case DHCP server 

is down and so on. The bootloader will start with first method, if it fails to bring up 

the board it will try the next method and so on. The user can specify up to four such 

boot methods.

The bootloader decides a boot method has failed based on the watchdog mechanism 

explained in 

. If the watchdog timer expires, it 

will use the next boot method in sequence. 

Following table lists the syntax of KV variable sX_bootXdevX that specifies the boot 
method.

Since colon(':') is used in the syntax of string, it can't be used in directory or file 

name.

For example, network boot using gmac2 and DHCP for second boot method in 

XLR1.

gmacN:IP[:mask][:gat

eway]

(static IP)

Select the boot GMAC port and specify 

the static host IP address to be used.

gmacN:dhcp_only

(dynamic IP)

Host IP address is requested from 

DHCP server.

gmacN:dhcp_tftp

(dynamic IP)

Host IP address, gateway, TFTP server 

and boot file name are requested from 

DHCP server.

Note that in this case user does not 

have to specify sX_bootXfileX variable.

cflash:partition

(CF card boot)  CF card as boot device, the partition 

field is the partition number.
