6.8 Boot into Bank 4 and Set More Variables
Next, enter the command “n710_reset altbank” to boot into bank 4 and press “any key” to stop
the boot. Check that u-boot prints “vBank: 4”. It is important that it does. If not, there is probably a
mistake in the previous steps.
Set variable bootcmd. The latter is shown below along with a “saveenv” to save the values.
setenv bootcmd setenv bootargs root=/dev/ram rw console=ttyS0,115200; bootm 0xe8020000
0xe9300000 0xe8800000
saveenv
U-boot has an environment variable “bootdelay” that controls the number of seconds u-boot
counts down before automatically running command “boot”. If you prefer to run “boot”
manually, set bootdelay to -1. This will cause u-boot to go directly to a command prompt. You
can set bootdelay to whatever you want.
setenv bootdelay -1
saveenv
6.9 Booting Linux
At this point, you need to reset once again into bank 4 (u-boot command “n710_reset
altbank”) and run the u-boot “boot” command, either manually or by letting it happen
automatically after the count-down.
Linux will boot and give you a login
prompt. Login as user “root” with
password “root”.
“ifconfig -a” should show only one FMan (fm) ethernet interface, fm1-gb1. This is the P4080
PCIE Adapter motherboard 1 G ethernet interface. You can set its IP address and use it as an
ordinary Linux network interface if you wish.
