From 4b35999588ee6dbe1fd818760b358b1191ddd0be Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Mon, 23 Nov 2020 13:41:34 +0100 Subject: ath79: Add support for OpenMesh MR600 v1 Device specifications: ====================== * Qualcomm/Atheros AR9344 rev 2 * 560/450/225 MHz (CPU/DDR/AHB) * 128 MB of RAM * 16 MB of SPI NOR flash - 2x 7 MB available; but one of the 7 MB regions is the recovery image * 2T2R 2.4 GHz Wi-Fi * 2T2R 5 GHz Wi-Fi * 4x GPIO-LEDs (2x wifi, 1x wps, 1x power) * 1x GPIO-button (reset) * TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX) * 1x ethernet - AR8035 ethernet PHY (RGMII) - 10/100/1000 Mbps Ethernet - 802.3af POE - used as LAN interface * 12-24V 1A DC * internal antennas Flashing instructions: ====================== Various methods can be used to install the actual image on the flash. Two easy ones are: ap51-flash ---------- The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be used to transfer the image to the u-boot when the device boots up. initramfs from TFTP ------------------- The serial console must be used to access the u-boot shell during bootup. It can then be used to first boot up the initramfs image from a TFTP server (here with the IP 192.168.1.21): setenv serverip 192.168.1.21 setenv ipaddr 192.168.1.1 tftpboot 0c00000 .bin && bootm $fileaddr The actual sysupgrade image can then be transferred (on the LAN port) to the device via scp .bin root@192.168.1.1:/tmp/ On the device, the sysupgrade must then be started using sysupgrade -n /tmp/.bin Signed-off-by: Sven Eckelmann [rebase, make WLAN LEDs consistent, add LED migration] Signed-off-by: Adrian Schmutzler --- target/linux/ath79/dts/ar9344_openmesh_mr600.dtsi | 133 ++++++++++++++++++++++ 1 file changed, 133 insertions(+) create mode 100644 target/linux/ath79/dts/ar9344_openmesh_mr600.dtsi (limited to 'target/linux/ath79/dts/ar9344_openmesh_mr600.dtsi') diff --git a/target/linux/ath79/dts/ar9344_openmesh_mr600.dtsi b/target/linux/ath79/dts/ar9344_openmesh_mr600.dtsi new file mode 100644 index 0000000000..987a32e344 --- /dev/null +++ b/target/linux/ath79/dts/ar9344_openmesh_mr600.dtsi @@ -0,0 +1,133 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "ar9344.dtsi" + +#include +#include + +/ { + chosen { + /delete-property/ bootargs; + }; + + aliases { + serial0 = &uart; + label-mac-device = ð0; + }; + + keys { + compatible = "gpio-keys"; + + reset { + label = "reset"; + linux,code = ; + gpios = <&gpio 17 GPIO_ACTIVE_LOW>; + }; + }; +}; + +&ref { + clock-frequency = <40000000>; +}; + +&uart { + status = "okay"; +}; + +&spi { + status = "okay"; + + flash@0 { + compatible = "jedec,spi-nor"; + reg = <0>; + spi-max-frequency = <40000000>; + + /* partitions are passed via bootloader */ + 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 = "custom"; + reg = <0x050000 0x060000>; + read-only; + }; + + partition@b0000 { + label = "inactive"; + reg = <0x0b0000 0x7a0000>; + }; + + partition@850000 { + label = "inactive2"; + reg = <0x850000 0x7a0000>; + }; + + art: partition@ff0000 { + label = "ART"; + reg = <0xff0000 0x010000>; + read-only; + }; + }; + }; +}; + +&mdio0 { + status = "okay"; + + phy-mask = <0x1>; + + phy0: ethernet-phy@0 { + reg = <0>; + eee-broken-100tx; + eee-broken-1000t; + }; +}; + +ð0 { + status = "okay"; + + pll-data = <0x06000000 0x00000101 0x00001313>; + + mtd-mac-address = <&art 0x0>; + + phy-mode = "rgmii"; + phy-handle = <&phy0>; + + gmac-config { + device = <&gmac>; + rgmii-gmac0 = <1>; + }; +}; + +&wmac { + status = "okay"; + + mtd-cal-data = <&art 0x1000>; + mtd-mac-address = <&art 0x0>; + mtd-mac-address-increment = <1>; +}; + +&pcie { + status = "okay"; + + ath9k: wifi@0,0 { + compatible = "pci168c,0030"; + reg = <0x0000 0 0 0 0>; + qca,no-eeprom; + mtd-mac-address = <&art 0x0>; + mtd-mac-address-increment = <8>; + }; +}; -- cgit v1.2.3
