From cf42660dcedf5b994eb9aa5f508ec9a7c301fddc Mon Sep 17 00:00:00 2001 From: Piotr Dymacz Date: Fri, 18 Sep 2020 14:11:13 +0200 Subject: [PATCH] ath79: add support for Samsung WAM250 Samsung WAM250 is a dual-band (selectable, not simultaneous) wireless hub, dedicated for Samsung Shape Wireless Audio System. The device is based on Atheros AR9344 (FCC ID: A3LWAM250). Support for this device was first introduced in e58e49bdbe (ar71xx target). Specifications: - Atheros AR9344 - 560/450/225 MHz (CPU/DDR/AHB) - 64 MB of RAM (DDR2) - 16 MB of flash (SPI NOR) - 2x 10/100 Mbps Ethernet - 2T2R 2.4/5 GHz Wi-Fi, with ext. PA (SE2598L, SE5003L) and LNA - 1x USB 2.0 - 4x LED (all are driven by GPIO) - 2x button (reset, wps/speaker add) - DC jack for main power input (14 V) - UART header on PCB (J4, RX: 3, TX: 5) Flash instruction: This device uses dual-image (switched between upgrades) with a common jffs2 config partition. Fortunately, there is a way to disable this mode so that more flash space can be used by OpenWrt image. You can easily access this device over telnet, using root/root credentials (the same also work for serial console access). 1. Make sure that your device uses second (bootpart=2) image using command: "fw_printenv bootpart". 2. If your device uses first image (bootpart=1), perform upgrade to the latest vendor firmware (after the update, device should boot from second partition) using web gui (default login: admin/1234567890). 3. Rename "sysupgrade" image to "firmware.bin", download it (you can use wget, tftp or ftpget) to "/tmp" and issue below commands: mtd_debug erase /dev/mtd3 0 $(wc -c /tmp/firmware.bin | awk -F' ' '{print $1}') mtd_debug write /dev/mtd3 0 $(wc -c /tmp/firmware.bin) fw_setenv bootpart fw_setenv bootcmd "bootm 0x9f070000" reboot Revert to vendor firmware instruction: 1. Download vendor firmware to "/tmp" device and issue below commands: fw_setenv bootpart 1 sysupgrade -n -F SS_BHUB_v2.2.05.bin Signed-off-by: Piotr Dymacz --- .../linux/ath79/dts/ar9344_samsung_wam250.dts | 163 ++++++++++++++++++ .../generic/base-files/etc/board.d/01_leds | 3 + target/linux/ath79/image/generic.mk | 10 ++ 3 files changed, 176 insertions(+) create mode 100644 target/linux/ath79/dts/ar9344_samsung_wam250.dts diff --git a/target/linux/ath79/dts/ar9344_samsung_wam250.dts b/target/linux/ath79/dts/ar9344_samsung_wam250.dts new file mode 100644 index 00000000000..3ae68d6104c --- /dev/null +++ b/target/linux/ath79/dts/ar9344_samsung_wam250.dts @@ -0,0 +1,163 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "ar9344.dtsi" + +#include +#include + +/ { + model = "Samsung WAM250"; + compatible = "samsung,wam250", "qca,ar9344"; + + aliases { + led-boot = &led_power; + led-failsafe = &led_power; + led-running = &led_power; + led-upgrade = &led_power; + }; + + keys { + compatible = "gpio-keys"; + + reset { + label = "reset"; + linux,code = ; + gpios = <&gpio 17 GPIO_ACTIVE_LOW>; + debounce-interval = <60>; + }; + + wps { + label = "wps"; + linux,code = ; + gpios = <&gpio 1 GPIO_ACTIVE_LOW>; + debounce-interval = <60>; + }; + }; + + leds { + compatible = "gpio-leds"; + + lan { + label = "wam250:white:lan"; + gpios = <&gpio 13 GPIO_ACTIVE_LOW>; + }; + + led_power: power { + label = "wam250:white:power"; + gpios = <&gpio 15 GPIO_ACTIVE_LOW>; + default-state = "keep"; + }; + + repeater { + label = "wam250:white:repeater"; + gpios = <&gpio 14 GPIO_ACTIVE_LOW>; + }; + + wlan { + label = "wam250:white:wlan"; + gpios = <&gpio 12 GPIO_ACTIVE_LOW>; + linux,default-trigger = "phy0tpt"; + }; + }; +}; + +ð0 { + status = "okay"; + + phy-handle = <&swphy0>; + + mtd-mac-address = <&art 0x1002>; + mtd-mac-address-increment = <1>; + + gmac-config { + device = <&gmac>; + switch-phy-swap = <1>; + }; +}; + +ð1 { + status = "okay"; + + mtd-mac-address = <&art 0x1002>; +}; + +&gpio { + lna0 { + line-name = "wam250:ext:lna0"; + gpios = <19 GPIO_ACTIVE_HIGH>; + output-high; + gpio-hog; + }; +}; + +&ref { + clock-frequency = <40000000>; +}; + +&spi { + status = "okay"; + + num-cs = <1>; + + flash@0 { + compatible = "jedec,spi-nor"; + reg = <0>; + spi-max-frequency = <50000000>; + m25p,fast-read; + + partitions { + compatible = "fixed-partitions"; + #address-cells = <1>; + #size-cells = <1>; + + partition@0 { + label = "u-boot"; + reg = <0x000000 0x040000>; + read-only; + }; + + partition@40000 { + label = "u-boot-env"; + reg = <0x040000 0x010000>; + }; + + partition@50000 { + label = "nvram"; + reg = <0x050000 0x020000>; + read-only; + }; + + partition@70000 { + compatible = "denx,uimage"; + label = "firmware"; + reg = <0x070000 0xf80000>; + }; + + art: partition@ff0000 { + label = "art"; + reg = <0xff0000 0x010000>; + read-only; + }; + }; + }; +}; + +&uart { + status = "okay"; +}; + + +&usb { + status = "okay"; +}; + +&usb_phy { + status = "okay"; +}; + + +&wmac { + status = "okay"; + + mtd-cal-data = <&art 0x1000>; +}; diff --git a/target/linux/ath79/generic/base-files/etc/board.d/01_leds b/target/linux/ath79/generic/base-files/etc/board.d/01_leds index 2b7b3bed553..78726afecfd 100755 --- a/target/linux/ath79/generic/base-files/etc/board.d/01_leds +++ b/target/linux/ath79/generic/base-files/etc/board.d/01_leds @@ -212,6 +212,9 @@ pcs,cr3000) qihoo,c301) ucidef_set_led_wlan "wlan" "WLAN" "$boardname:green:wlan" "phy0tpt" ;; +samsung,wam250) + ucidef_set_led_netdev "lan" "LAN" "$boardname:white:lan" "eth0" + ;; tplink,archer-a7-v5|\ tplink,archer-c7-v4|\ tplink,archer-c7-v5) diff --git a/target/linux/ath79/image/generic.mk b/target/linux/ath79/image/generic.mk index 5d1058cae26..ce927ecd4f2 100644 --- a/target/linux/ath79/image/generic.mk +++ b/target/linux/ath79/image/generic.mk @@ -1415,6 +1415,16 @@ define Device/rosinson_wr818 endef TARGET_DEVICES += rosinson_wr818 +define Device/samsung_wam250 + SOC := ar9344 + DEVICE_VENDOR := Samsung + DEVICE_MODEL := WAM250 + IMAGE_SIZE := 15872k + DEVICE_PACKAGES := kmod-usb2 + SUPPORTED_DEVICES += wam250 +endef +TARGET_DEVICES += samsung_wam250 + define Device/siemens_ws-ap3610 SOC := ar7161 DEVICE_VENDOR := Siemens
