ea9x00_openwrt

OpenWrt support for the Linksys EA9500, EA9400, and EA9200

This repository aims to support the Linksys EA9500/EA9400 (linksys,panamera) and the Linksys EA9200 (linksys,ea9200) using the swconfig driver and configuration framework.

Components

• clear_partialboot : Ensures that Linksys dual-partition routers always boot to the correct partition
• EA9500: brcmfmac-firmware-4366c0-pcie-panamera : Wireless firmware package that allows all three radios on EA9500 to function
• EA9400: brcmfmac-firmware-4366b1-pcie-panamera : Wireless firmware package that allows all three radios on EA9400 to function

Building

Step 1

To build OpenWrt for EA9x00, you must first add this feed to your feeds.conf

src-git ea9500_openwrt https://github.com/hurrian/ea9500_openwrt.git

$ ./scripts/feeds update -a
$ ./scripts/feeds install -a

Step 2

The custom configuration overlay needs to be enabled by using the custom files feature of the OpenWrt buildroot. While in your buildroot directory (ex. ~/openwrt), run the following command:

~/openwrt $   ln -s feeds/ea9500_openwrt/files files

Step 3A: For Linksys EA9500

You must then edit the Linksys EA9500 target in target/linux/bcm53xx/image/Makefile by uncommenting TARGET_DEVICES += linksys-ea9500, and setting DEVICE_PACKAGES = $(IEEE8021X) kmod-brcmfmac brcmfmac-firmware-4366c0-pcie-panamera $(USB3_PACKAGES)

define Device/linksys-ea9500
  DEVICE_VENDOR := Linksys
  DEVICE_MODEL := EA9500
  DEVICE_PACKAGES := $(IEEE8021X) kmod-brcmfmac brcmfmac-firmware-4366c0-pcie-panamera $(USB3_PACKAGES)
  DEVICE_DTS := bcm47094-linksys-panamera
endef
TARGET_DEVICES += linksys-ea9500

Step 3B: For Linksys EA9400

You must add a target for Linksys EA9400 by adding the following into target/linux/bcm53xx/image/Makefile:

define Device/linksys-ea9400
  DEVICE_VENDOR := Linksys
  DEVICE_MODEL := EA9400
  DEVICE_PACKAGES := $(IEEE8021X) kmod-brcmfmac brcmfmac-firmware-4366b1-pcie-panamera $(USB3_PACKAGES)
  DEVICE_DTS := bcm47094-linksys-panamera
endef
TARGET_DEVICES += linksys-ea9400

Step 3C: For Linksys EA9200

Enable the Linksys EA9200 target in target/linux/bcm53xx/image/Makefile by uncommenting TARGET_DEVICES += linksys-ea9200

define Device/linksys-ea9200
  DEVICE_VENDOR := Linksys
  DEVICE_MODEL := EA9200
  DEVICE_VARIANT := v1
  DEVICE_PACKAGES := $(BRCMFMAC_43602A1) $(USB3_PACKAGES)
endef
TARGET_DEVICES += linksys-ea9200

Step 4

In make menuconfig, you must select Base System -> clear_partialboot <*>. You may then add any additional packages you want to use.

Step 5

Issue the command to build OpenWrt.

~/openwrt $ make V=s

You will find the built images at bin/targets/bcm53xx/generic.

Quirks

The CPU ports of the EA9500/EA9400 are directly connected to a BCM53012 switch wired to LAN4,7,8 plus an external BCM53125 switch wired to LAN1,2,3,5,6. This means that you will only see the internal BCM53012 ports in LuCI's switch configuration.

On EA9500, Broadcom BCM4366C0 firmware versions past 10.10.69.69 are not properly supported by brcmfmac, resulting in dropouts in the 2.4GHz and secondary 5GHz radios. The latest known working firmware for BCM4366C0 is supplied in the package brcmfmac-firmware-4366c0-pcie-panamera.
