From 6c98edaae20ac1dd0364963aadeecb022f6a80a1 Mon Sep 17 00:00:00 2001 From: Michael Pratt Date: Fri, 9 Oct 2020 12:28:11 -0400 Subject: [PATCH] ath79: add support for Senao Engenius EAP600 FCC ID: A8J-EAP600 Engenius EAP600 is a wireless access point with 1 gigabit ethernet port, dual-band wireless, external ethernet switch, 4 internal antennas and 802.3af PoE. Specification: - AR9344 SOC (5 GHz, 2x2, WMAC) - AR9382 WLAN (2.4 GHz, 2x2, PCIe on-board) - AR8035-A switch (GbE with 802.3af PoE) - 40 MHz reference clock - 16 MB FLASH MX25L12845EMI-10G - 2x 64 MB RAM NT5TU32M16DG - UART at H1 (populated) - 5 LEDs, 1 button (power, eth, 2.4 GHz, 5 GHz, wps) (reset) - 4 internal antennas MAC addresses: MAC addresses are labeled MAC1 and MAC2 The MAC address in flash is not on the label The OEM software reports these MACs for the ifconfig eth0 MAC 1 *:5e --- phy1 MAC 2 *:5f --- (2.4 GHz) phy0 ----- *:60 art 0x0 (5 GHz) Installation: 2 ways to flash factory.bin from OEM: - if you get Failsafe Mode from failed flash: only use it to flash Original firmware from Engenius or risk kernel loop or halt which requires serial cable Method 1: Firmware upgrade page: OEM webpage at 192.168.1.1 username and password "admin" Navigate to "Upgrade Firmware" page from left pane Click Browse and select the factory.bin image Upload and verify checksum Click Continue to confirm and wait 3 minutes Method 2: Serial to load Failsafe webpage: After connecting to serial console and rebooting... Interrupt uboot with any key pressed rapidly execute `run failsafe_boot` OR `bootm 0x9fdf0000` wait a minute connect to ethernet and navigate to "192.168.1.1/index.htm" Select the factory.bin image and upload wait about 3 minutes Return to OEM: If you have a serial cable, see Serial Failsafe instructions otherwise, uboot-env can be used to make uboot load the failsafe image *DISCLAIMER* The Failsafe image is unique to Engenius boards. If the failsafe image is missing or damaged this will not work DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt ssh into openwrt and run `fw_setenv rootfs_checksum 0` reboot, wait 3 minutes connect to ethernet and navigate to 192.168.1.1/index.htm select OEM firmware image from Engenius and click upgrade Format of OEM firmware image: The OEM software of EAP600 is a heavily modified version of Openwrt Kamikaze. One of the many modifications is to the sysupgrade program. Image verification is performed simply by the successful ungzip and untar of the supplied file and name check and header verification of the resulting contents. To form a factory.bin that is accepted by OEM Openwrt build, the kernel and rootfs must have specific names... openwrt-senao-eap600-uImage-lzma.bin openwrt-senao-eap600-root.squashfs and begin with the respective headers (uImage, squashfs). Then the files must be tarballed and gzipped. The resulting binary is actually a tar.gz file in disguise. This can be verified by using binwalk on the OEM firmware images, ungzipping then untaring. The OEM upgrade script is at /etc/fwupgrade.sh Later models in the EAP series likely have a different platform and the upgrade and image verification process differs. OKLI kernel loader is required because the OEM software expects the kernel to be no greater than 1536k and the factory.bin upgrade procedure would overwrite part of the kernel when writing rootfs. Note on PLL-data cells: The default PLL register values will not work because of the external AR8035-A switch between the SOC and the ethernet PHY chips. For AR934x series, the PLL register for GMAC0 can be seen in the DTSI as 0x2c. Therefore the PLL register can be read from uboot for each link speed after attempting tftpboot or another network action using that link speed with `md 0x1805002c 1`. Unfortunately uboot did not have the best values so they were taken from other similar DTS files. Tested from master, all link speeds functional Signed-off-by: Michael Pratt --- package/boot/uboot-envtools/files/ath79 | 1 + .../ath79/dts/ar9344_engenius_eap600.dts | 45 +++++++++++++++++++ .../generic/base-files/etc/board.d/02_network | 1 + .../etc/hotplug.d/firmware/10-ath9k-eeprom | 1 + target/linux/ath79/image/generic.mk | 10 +++++ 5 files changed, 58 insertions(+) create mode 100644 target/linux/ath79/dts/ar9344_engenius_eap600.dts diff --git a/package/boot/uboot-envtools/files/ath79 b/package/boot/uboot-envtools/files/ath79 index 4cfcdd3066..8f4b8ef31e 100644 --- a/package/boot/uboot-envtools/files/ath79 +++ b/package/boot/uboot-envtools/files/ath79 @@ -24,6 +24,7 @@ arduino,yun|\ buffalo,bhr-4grv2|\ devolo,magic-2-wifi|\ engenius,eap300-v2|\ +engenius,eap600|\ engenius,ecb1200|\ engenius,ecb1750|\ engenius,ecb350-v1|\ diff --git a/target/linux/ath79/dts/ar9344_engenius_eap600.dts b/target/linux/ath79/dts/ar9344_engenius_eap600.dts new file mode 100644 index 0000000000..c6961f636e --- /dev/null +++ b/target/linux/ath79/dts/ar9344_engenius_eap600.dts @@ -0,0 +1,45 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "ar9344_engenius_exx600.dtsi" + +/ { + model = "EnGenius EAP600"; + compatible = "engenius,eap600", "qca,ar9344"; + + leds { + compatible = "gpio-leds"; + + led_power: power { + label = "amber:power"; + gpios = <&gpio 14 GPIO_ACTIVE_LOW>; + default-state = "on"; + }; + + wps { + label = "blue:wps"; + gpios = <&gpio 13 GPIO_ACTIVE_LOW>; + }; + + wifi5g { + label = "green:wifi5g"; + gpios = <&gpio 12 GPIO_ACTIVE_LOW>; + linux,default-trigger = "phy0tpt"; + }; + }; +}; + +ð0 { + mtd-mac-address = <&art 0x0>; + mtd-mac-address-increment = <(-2)>; +}; + +&pcie { + wifi@0,0,0 { + mtd-mac-address = <&art 0x0>; + }; +}; + +&wmac { + mtd-mac-address = <&art 0x0>; + mtd-mac-address-increment = <(-1)>; +}; diff --git a/target/linux/ath79/generic/base-files/etc/board.d/02_network b/target/linux/ath79/generic/base-files/etc/board.d/02_network index a3b5d45ad2..355ea25b4d 100755 --- a/target/linux/ath79/generic/base-files/etc/board.d/02_network +++ b/target/linux/ath79/generic/base-files/etc/board.d/02_network @@ -29,6 +29,7 @@ ath79_setup_interfaces() dlink,dap-1365-a1|\ dlink,dir-505|\ engenius,eap300-v2|\ + engenius,eap600|\ engenius,ecb1200|\ engenius,ecb1750|\ engenius,ecb350-v1|\ diff --git a/target/linux/ath79/generic/base-files/etc/hotplug.d/firmware/10-ath9k-eeprom b/target/linux/ath79/generic/base-files/etc/hotplug.d/firmware/10-ath9k-eeprom index 867a1dac44..553db59231 100644 --- a/target/linux/ath79/generic/base-files/etc/hotplug.d/firmware/10-ath9k-eeprom +++ b/target/linux/ath79/generic/base-files/etc/hotplug.d/firmware/10-ath9k-eeprom @@ -88,6 +88,7 @@ case "$FIRMWARE" in caldata_extract "art" 0x5000 0x440 ath9k_patch_mac $(macaddr_add $(mtd_get_mac_text "mac" 0x18) 1) ;; + engenius,eap600|\ engenius,ecb600|\ mercury,mw4530r-v1|\ ocedo,raccoon|\ diff --git a/target/linux/ath79/image/generic.mk b/target/linux/ath79/image/generic.mk index 064177fcaf..8f9e7159d1 100644 --- a/target/linux/ath79/image/generic.mk +++ b/target/linux/ath79/image/generic.mk @@ -965,6 +965,16 @@ define Device/engenius_eap300-v2 endef TARGET_DEVICES += engenius_eap300-v2 +define Device/engenius_eap600 + $(Device/engenius_loader_okli) + SOC := ar9344 + DEVICE_MODEL := EAP600 + IMAGE_SIZE := 12032k + LOADER_FLASH_OFFS := 0x230000 + ENGENIUS_IMGNAME := senao-eap600 +endef +TARGET_DEVICES += engenius_eap600 + define Device/engenius_ecb1200 SOC := qca9557 DEVICE_VENDOR := EnGenius -- 2.30.2
