495EdgeRouter Lite(edgerouter)
496=====================================
497
498The EdgeRouter Lite is part of the EdgeMax series. It is an MIPS64 router(Cavium Octeon)
499with 512MB of RAM, which uses a USB pendrive for storage.

501Setup instructions
502------------------
503
504You will need the following:
505* NFS root setup on your workstation
506* TFTP server installed on your workstation
507* Straight-thru 9-conductor serial cable (DB9, M/F) connected from your
508 PC to UART1
509* Ethernet connected to the first ethernet port on the board
510
511--- Preparation ---
512
513Build an image (e.g. core-image-minimal) using "edgerouter" as the MACHINE.
514In the following instruction it is based on core-image-minimal. Another target
515may be similiar with it.
516
517--- Booting from NFS root ---
518
519Load the kernel, and boot the system as follows:
520
521 1. Get the kernel (vmlinux) file from the tmp/deploy/images/edgerouter
522 directory, and make them available on your TFTP server.
523
524 2. Connect the board's first serial port to your workstation and then start up
525 your favourite serial terminal so that you will be able to interact with
526 the serial console. If you don't have a favourite, picocom is suggested:
527
528 $ picocom /dev/ttyS0 -b 115200
529
530 3. Power up or reset the board and press a key on the terminal when prompted
531 to get to the U-Boot command line
532
533 4. Set up the environment in U-Boot:
534
535 => setenv ipaddr <board ip>
536 => setenv serverip <tftp server ip>
537
538 5. Download the kernel and boot:
539
540 => tftp tftp $loadaddr vmlinux
541 => bootoctlinux $loadaddr coremask=0x3 root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:<netmask>:edgerouter:eth0:off mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
542
543--- Booting from USB root ---
544
545NOTE: Since the USB disk is inside the edgerouter box, its inconvenient for us to
546 plug and unplug the USB disk. So in the following instructions I assume that
547 you already boot the box from NFS. Additionally, since vmlinux is not installed
548 to core-minal-image-xxx by default, so its neccessary for us to copy it to USB
549 disk.
550
551Load the kernel, and boot the system as follows:
552 1. Booting from NFS root
553
554 2. Mount usb disk partition 2 and then extract the contens of
555 tmp/deploy/core-image-XXXX.tar.bz2 into it.
556
557 Before starting, copy core-image-minimal-xxx.tar.bz2 and vmlinux into
558 rootfs path on your workstation.
559
560 and then,
561
562 # mount /dev/sda2 /media/sda2
563 # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /media/sda2
564 # cp vmlinux /media/sda2/boot/vmlinux
565 # umount /media/sda2
566 # reboot
567
568 3. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
569 command line
570 # reboot
571
572 4. Load the kernel and boot:
573
574 => ext2load usb 0:2 $loadaddr boot/vmlinux
575 => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
