<!-- GoldCoastRouter, Version: 6, Modified: 2021/04/15, Author: feurig -->
#Gold Coast
Gold Coast (goldcoast.lan) is the house router for portland. The configuration and this doc are at https://bitbucket.org/houselan/config/src/master/
## LEDE 19.07 on the Ubiquity ER-lite3
The Ubiquity EdgeRouter Lite is my new favorite OpenWrt device. It is fast and inexpensive ($150 new) and the os is on a USB Stick.
[[Image(https://prd-www-cdn.ubnt.com/media/images/product-features/ER-lite-features-UNMS.jpg)]]
### Pros
* 3 independent Gigabit network ports.
* Serial Console
* Cheap and still supported.
* Stock Edge-os would work for most tasks.
* OS on a USB-stick easiest backup and install EVER.
* 512 K of memory.
### Cons (some assembly required)
* Because the stock usb stick and (unused) flash is only 4K LEDE considers it a 4K and are threatening to stop producing stock images after 19.07.
* Third party usb sticks take longer to start up than the on board bootloader (U-boot) expects. So a pause and usb reset need to be configured.
## How do I get set up?
### Building 19.07 for the device
Getting the source. See LEDE documentation for dependencies.
feurig@vasily:~$ git clone https://git.openwrt.org/openwrt/openwrt.git
Building for the target
feurig@vasily:~$ cd openwrt/
feurig@vasily:~/openwrt$ make clean
feurig@vasily:~/openwrt$ git pull
feurig@vasily:~/openwrt$ ./scripts/feeds update -a
feurig@vasily:~/openwrt$ ./scripts/feeds install -a
feurig@vasily:~/openwrt$ make menuconfig
feurig@vasily:~/openwrt$ make -j8 download world
feurig@vasily:~/openwrt$ mv bin/targets/octeon/generic/openwrt-octeon-ubnt_edgerouter-lite-ext4-sysupgrade.tar.gz ~/firmware/
feurig@vasily:~/openwrt$ ./scripts/diffconfig.sh > ../firmware/openwrt-octeon-ubnt_edgerouter-lite-ext4-sysupgrade.diffconfig
### Deploying the image
Download the image from vasily
feurig@colbert:~ $ scp feurig@wrt.suspectdevices.com:firmware/openwrt-octeon-ubnt_edgerouter-lite-ext4-sysupgrade.tar.gz .
Format the stick with 2 partitions (142M dos and the lemaining linux)
root@colbert:~ # fdisk -l
... On our machine, this is our disk ...
Disk /dev/sda: 7.6 GiB, 8166703104 bytes, 15950592 sectors
...
root@colbert:~ # fdisk /dev/sda
... Partition disk here ...
root@colbert:~ # fdisk -l
...
Disk /dev/sda: 7.6 GiB, 8166703104 bytes, 15950592 sectors
Disk model: USB 2.0 FD
...
Device Boot Start End Sectors Size Id Type
/dev/sda1 2048 292863 290816 142M c W95 FAT32 (LBA)
/dev/sda2 292864 3710975 3418112 1.6G 83 Linux
...
root@colbert:/home/feurig# mkfs.vfat /dev/sda1
root@colbert:/home/feurig# mkfs.ext4 /dev/sda2
Copy firmware to usb stick
root@colbert:~ # mkdir scratch
root@colbert:~ # cd scratch/
root@colbert:~ # tar -xf ../openwrt-octeon-ubnt_edgerouter-lite-ext4-sysupgrade.tar.gz
root@colbert:~ # mkdir root oroot kernel
root@colbert:~ # mount /dev/sda1 kernel/
root@colbert:~ # mount /dev/sda2 root/
root@colbert:~ # mount sysupgrade-erlite/root oroot -o loop
root@colbert:~ # cp sysupgrade-erlite/kernel kernel/vmlinux.64
root@colbert:~ # md5sum sysupgrade-erlite/kernel | cut -d' ' -f 1 > kernel/vmlinux.64.md5
root@colbert:~ # rsync -aHAX oroot/* root/
root@colbert:~ # umount kernel root oroot
root@colbert:~ # sync
### Fixing the bootloader for standard USB Sticks.
If the usb stick used takes longer than the stock one to initialize the boot will fail.
don$ screen /dev/tty.usbserial 115200
...
U-Boot 1.1.1 (UBNT Build ID: 4670715-gbd7e2d7) (Build time: May 27 2014 - 11:16:22)

Getting the stock boot command
Octeon ubnt_e100# printenv

nuke_env=protect off $(env_addr) +$(env_size);erase $(env_addr) +$(env_size)

bootcmd=fatload usb 0 $loadaddr vmlinux.64;bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rootdelay=15 rw rootsqimg=squashfs.img rootsqwdir=w mtd
...
Copy the bootcmd from the existing environment and add a delay and usb reset
Octeon ubnt_e100# setenv bootcmd 'sleep 10;usb reset;fatload usb 0 $loadaddr vmlinux.64;bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rootdelay=15 rw rootsqimg=squashfs.img rootsqwdir=w mtd'
Octeon ubnt_e100# saveenv
Octeon ubnt_e100# reset

* dnsmasq
* firewall
* /etc/ethers
