David Bauer daf1fdc6ad ath79: add support for ZTE MF281 ... Add support for the ZTE MF281 battery-powered WiFi router. Hardware -------- SoC: Qualcomm Atheros QCA9563 RAM: 128M DDR2 FLASH: 2M SPI-NOR (GigaDevice GD25Q16) 128M SPI-NAND (GigaDevice) WLAN: QCA9563 2T2R 802.11 abgn QCA9886 2T2R 802.11 nac WWAN: ASRMicro ASR1826 ETH: Qualcomm Atheros QCA8337 UART: 115200 8n1 Unpopulated connector next to SIM slot (SIM) GND - RX - TX - 3V3 Don't connect 3V3 BUTTON: Reset - WPS LED: 1x debug-LED (internal) LEDs on front of the device are controlled using the modem CPU and can not be controlled by OpenWrt Installation ------------ 1. Connect to the serial console. Power up the device and interrupt autoboot when prompted 2. Connect a TFTP server reachable at 192.168.1.66 to the ethernet port. Serve the OpenWrt initramfs image as "speedbox-2.bin" 3. Boot the initramfs image using U-Boot $ setenv serverip 192.168.1.66 $ setenv ipaddr 192.168.1.154 $ tftpboot 0x84000000 speedbox-2.bin $ bootm 4. Copy the OpenWrt factory image to the device using scp and write to the NAND flash $ mtd write /path/to/openwrt/factory.bin firmware WWAN ---- The WWAN card can be used with OpenWrt. Example configuration for connection with a unauthenticated dual-stack APN: network.lte=interface network.lte.proto='ncm' network.lte.device='/dev/ttyACM0' network.lte.pdptype='IPV4V6' network.lte.apn='internet.telekom' network.lte.ipv6='auto' network.lte.delay='10' The WWAN card is running a modified version of OpenWrt and handles power-management as well as the LED controller (AW9523). A root shell can be acquired by installing adb using opkg and executing "adb shell".
