From 1f06144cdec1487122201faa9350825ed565d99c Mon Sep 17 00:00:00 2001 From: Piotr Dymacz Date: Sun, 15 Oct 2017 13:24:02 +0200 Subject: ar71xx: add support for Teltonika RUT900 Teltonika RUT900 is an industrial 3G router based on Atheros AR9344. There are available 3 other models in RUT9xx series: RUT905, RUT950 and RUT955, which differ in availability of additional I/O ports, built-in GSM modem type, GPS antenna and other features. FCC ID of the RUT950 model (LTE module built-in): 2AET4-RUT950. This patch adds support for the RUT900 model only but can be easily extended to cover whole series. Also, as there are several different 3/4G modules (Huawei, Quectel, Telit) used in whole series, packages required for WWAN support are not included by default. It is up to the user to install required software for built-in modem. Specification: - 550/400/200 MHz (CPU/DDR/AHB) - 128 MB of RAM (DDR2) - 16 MB of FLASH (SPI NOR) - 4x 10/100 Mbps Ethernet, with passive PoE support on LAN1 - 2T2R 2,4 GHz (AR9344), with ext. PA (MGA-22103) and LNA - built-in 3G module (example: Telit HE910-D) - 2x miniSIM slot - 2x RP-SMA/F (Wi-Fi), 2x SMA/F (3G) - PCA9539 16-bit GPIO I2C expander - 12x LED (4 are driven by AR9344, 7 by PCA9539) - 1x button (reset) - DC jack for main power input (9-30 V) - UART available on PCB edge connector Serial console pinout: - RX: pin1 (square) on top side of the main PCB (AR9344 is on top) - TX: pin1 (square) on bottom side Flash instruction: Vendor firmware is based on OpenWrt CC release. Use the "factory" image directly in GUI (make sure to uncheck "keep settings") or in U-Boot web based recovery. To avoid any problems, make sure to first update vendor firmware to latest version - "factory" image was successfully tested on device running "RUT9XX_R_00.03.960" firmware and U-Boot "3.0.1".
