Freescale Semiconductor 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 <strong>P4080</strong> PCIE <strong>Adapter</strong> motherboard 1 G ethernet interface. You can set its IP address and use it as an ordinary Linux network interface if you wish. © Freescale Semiconductor, Inc., 2011. All rights reserved. Freescale Confidential Proprietary Page 43
