# HOWTO Build Maxwell
|
|
|
|
This documents how to build the Maxwell meshing software
|
|
with OpenWRT.
|
|
|
|
Base system is Debian Bullseye (11/testing) on ppc64le architecture.
|
|
Should also work fine on x86_64.
|
|
|
|
# Build thang
|
|
Do.
|
|
|
|
OpenWRT build system:
|
|
|
|
* https://openwrt.org/docs/guide-developer/build-system/start
|
|
|
|
## Install Dependencies
|
|
|
|
Dependencies for other distros are listed here:
|
|
|
|
* https://openwrt.org/docs/guide-developer/build-system/install-buildsystem#examp
|
|
|
|
Get current:
|
|
|
|
```
|
|
apt update
|
|
```
|
|
|
|
Upstream command suggests for Debian:
|
|
|
|
```
|
|
apt install build-essential ccache ecj fastjar file g++ gawk \
|
|
gettext git java-propose-classpath libelf-dev libncurses5-dev \
|
|
libncursesw5-dev libssl-dev python python2.7-dev python3 unzip wget \
|
|
python3-distutils python3-setuptools python3-dev rsync subversion swig time \
|
|
xsltproc zlib1g-dev
|
|
```
|
|
|
|
Full docs list more dependencies for full list, that work with Debian Bullseye.
|
|

|
Maybe want to use `ccache` to save on rebuilds:
|
|
|
|
```
|
|
apt install ccache
|
|
```
|
|
|
|
Add to your `~/.bashrc`:
|
|
|
|
```
|
|
PATH=/usr/lib/ccache:$PATH
|
|
```
|
|
|
|
Then log out and back in and run `echo $PATH` to make sure it is there.
|
|
Run `ccache -s` during build to see cache hit rate.
|
|
|
|
## Get Source
|
|
|
|
Clone OpenWRT sources, around ~300 megs:
|
|
|
|
```
|
|
git clone https://git.openwrt.org/openwrt/openwrt.git
|
|
cd openwrt
|
|
```
|
|
|
|
|
|
Add Maxwell source code, around ~5 megs, to `openwrt` directory:
|
|
|
|
```
|
|
git clone https://github.com/drandyhaas/haasmesh.git
|
|
```
|
|
|
|
## Configure Build
|
|
|
|
If you've done other builds, it is good to clean up first, maybe:
|
|
|
|
```
|
|
make clean
|
|
```
|
|
|
|
There are a variety of units the setup script is compatible with:
|
|
|
|
* luma
|
|
* Maxwell Indoor 3-Band: ea8300
|
|
* Maxwell Outdoor 2-Band: ew72
|
|
* c7v2
|
|
* c7v5
|
|
* jetstream
|
|
* redmi
|
|
|
|
You will need to check out the correct git branch or commit depending
|
|
on your radio.
|
|
|
|
|
|
To get the stock version `OpenWrt 19.07.4, r11208-ce6496d796` of the Maxwell Indoor 3-Band EA8300:
|
|
|
|
```
|
|
git checkout ce6496d796
|
|
```
|
|
|
|
To get the stock version `OpenWrt SNAPSHOT, r14229-b52b4afa15` of the Maxwell Outdoor 2-Band EW-72:
|
|
|
|
```
|
|
git checkout b52b4afa15
|
|
```
|
|
|
|
TODO: Add more versions, newer releases.
|
|
|
|
|
|
Pull in more needful things:
|
|
|
|
```
|
|
# Takes about ~1 min:
|
|
./scripts/feeds update -a
|
|
# Takes less than 1 min:
|
|
./scripts/feeds install -a
|
|
```
|
|
|
|
|
|
To build, run the build script with one of these options.
|
|
|
|
```
|
|
haasmesh/script/setupnodebuild.sh [luma|ea8300|ew72|c7v2|c7v5|jetstream|redmi]
|
|
```
|
|
|
|
For example, to configure the build system for the Maxwell Outdoor 2-Band, run below.
|
|
The configure script should run in ~1 second.
|
|
|
|
```
|
|
haasmesh/script/setupnodebuild.sh ew72
|
|
```
|
|
|
|
This is a sample `.config` file that can be used for EW-72:
|
|
|
|
```
|
|
wget -O .config https://spacecruft.org/network/maxwell/raw/branch/master/config/dot-config-ew-72
|
|
```
|
|
|
|
Run menuconfig:
|
|
|
|
```
|
|
make menuconfig
|
|
```
|
|
|
|
Or, if you used the `.config` from above, you can skip `menuconfig` and run:
|
|
|
|
```
|
|
make defconfig
|
|
```
|
|
|
|
In there, there are a few options needed to select, which should be already including in above config:
|
|
|
|
```
|
|
network -> alfred (with auto bat-hosts) batctl-full iperf3
|
|
network/wirelessAPD -> remove wpad-basic, install wpad-mesh-openssl
|
|
network/filetransfer -> wget
|
|
network/ssh -> openssh-client-utils
|
|
utilities/compression -> unzip
|
|
utilities/editors -> nano
|
|
utilities/bootloader -> uboot-envtools
|
|
kernel/network support-> kmod-batman-adv
|
|
kernel/wireless drivers -> kmod-rt2800-usb (for alfa r36a)
|
|
firmware -> ath10k non-ct drivers and kmod-ath10k non-ct (for wave-1 devices only, like archer)
|
|
firmware -> ath10k-firmware-qca9888-ct (for ea8300)
|
|
development -> diffutils
|
|
luci, luci-app-commands
|
|
for luma also add:
|
|
utilities -> i2c-tools, nand-utils, usbutils
|
|
kernel/filesystems -> kmod-fs-exfat, kmod-fs-ext4, kmod-fs-vfat, kmod-usb-storage
|
|
```
|
|
|
|
TODO: What kernel wifi modules on EW-72? Use `ath9k` and `ath10k` for now.
|
|
|
|
TODO: Make `defconfig` for different hardware.
|
|
|
|
Hit `<TAB>` to get to `EXIT`, then `<ENTER>` to select `Yes` to save the configuration.

Download more sources:
|
|
|
|
```
|
|
make -j1 download
|
|
```
|
|
|
|
## Build Source
|
|
|
|
Now, actually build it. Takes over an hour or two, depending on hardware.
|
|
|
|
```
|
|
make -j`nproc`
|
|
```
|
|
|
|
## MISC HACKS
|
|
|
|
Notes on things that need to be done too:
|
|
|
|
```
|
|
For the Archer, you need the source patch I discuss in this thread, so you can raise the mtu...
|
|
https://forum.openwrt.org/t/ag71xx-gigabit-e-g-archer-c7-v5-eth-raising-mtu-problem-regression/44138/
|
|
|
|
For the Linksys I had to follow this thread (which really just means deleting a patch file)
|
|
https://forum.openwrt.org/t/vlan-tagging-on-ipq40xx-gl-b1300-no-longer-works/69569/58
|
|
so that vlans work, which is needed for separate lan, wan, and backhaul
|
|
```
|
|
|
|
Also better for ssh config in OpenWRT build, enable:
|
|
|
|
```
|
|
Base system --> Dropbear Configuration --> Ed25519 support
|
|
```
