FCC ID: A8J-ESR900
Engenius ESR900 is an indoor wireless router with
a gigabit ethernet switch, dual-band wireless,
internal antenna plates, and a USB 2.0 port
**Specification:**
- QCA9558 SOC 2.4 GHz, 3x3
- AR9580 WLAN PCIe on board, 5 GHz, 3x3
- AR8327N SW 4 ports LAN, 1 port WAN
- 40 MHz clock
- 16 MB FLASH MX25L12845EMI-10G
- 2x 64 MB RAM
- UART at J1 populated, RX grounded
- 6 internal antenna plates (omni-directional)
- 5 LEDs, 1 button (power, 2G, 5G, WAN, WPS) (reset)
**MAC addresses:**
Base MAC address labeled as "MAC ADDRESS"
MAC "wanaddr" is not similar to "ethaddr"
eth0 *:06 MAC u-boot-env ethaddr
phy0 *:06 MAC u-boot-env ethaddr
phy1 *:07 --- u-boot-env ethaddr +1
WAN *:6E:81 u-boot-env wanaddr
**Serial Access:**
RX on the board for UART is shorted to ground by resistor R176
therefore it must be removed to use the console
but it is not necessary to remove to view boot log
optionally, R175 can be replaced with a solder bridge short
the resistors R175 and R176 are next to the UART RX pin
**Installation:**
Method 1: Firmware upgrade page
OEM webpage at 192.168.0.1
username and password "admin"
Navigate to Settings (gear icon) --> Tools --> Firmware
select the factory.bin image
confirm and wait 3 minutes
Method 2: TFTP recovery
Follow TFTP instructions using initramfs.bin
use sysupgrade.bin to flash using openwrt web interface
**Return to OEM:**
MTD partitions should be backed up before flashing
using TFTP to boot openwrt without overwriting flash
Alternatively, it is possible to edit OEM firmware images
to flash MTD partitions in openwrt to restore OEM firmware
by removing the OEM header and writing the rest to "firmware"
**TFTP recovery:**
Requires serial console, reset button does nothing at boot
rename initramfs.bin to 'uImageESR900'
make available on TFTP server at 192.168.99.8
power board, interrupt boot by pressing '4' rapidly
execute tftpboot and bootm
**Note on ETH switch registers**
Registers must be written to the ethernet switch
in order to set up the switch's MAC interface.
U-boot can write the registers on it's own
which is needed, for example, in a TFTP transfer.
The register bits from OEM for the AR8327 switch
can be read from interrupted boot (tftpboot, bootm)
by adding print lines in the switch driver ar8327.c
before 'qca,ar8327-initvals' is parsed from DTS and written.
for example:
pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.6+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
Related Repositories
The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
