From 80829022b044d2109056b5e6e35bf16b9daf0719 Mon Sep 17 00:00:00 2001 From: Kristian Evensen Date: Wed, 6 Sep 2017 11:14:16 +0200 Subject: [PATCH] ramips: add support for the HNET C108 The HNET C108 (http://www.szhwtech88.com/Product-product-cid-100-id-4374.html) is a mifi based on MT7602A, which has the following specifications: * CPU: MT7620A * 1x 10/100Mbps Ethernet. * 16 MB Flash. * 64 MB RAM. * 1x USB 2.0 port. Only power is connected, this port is meant for charging other devices. * 1x mini-PCIe slots. * 1x SIM slots. * 1x 2.4Ghz WIFI. * 1x button. * 6000 mAh battery. * 5x controllable LEDs. Works: * Wifi. * Switch. * mini-PCIe slot. Only tested with a USB device (a modem). * SIM slot. * Sysupgrade. * Button (reset). Not working (also applies to the factory firmware): * Wifi LED. It is always switched on, there is no relation to the up/down state or activity of the wireless interface. Not tested: * SD card reader. Notes: * The C108 has no dedicated status LED. I therefore set the LAN LED as status LED. Installation: The router comes pre-installed with OpenWRT, including a variant of Luci. The initial firmware install can be done through this UI, following normal procedure. I.e., access the UI and update the firmware using the sysupgrade-image. Remember to select that you do not want to keep existing settings. Recovery: If you brick the device, the C108 supports recovery using TFTP. Keep the reset button pressed for ~5sec when booting to trigger TFTP. Set the address of the network interface on your machine to 10.10.10.3/24, and rename your image file to Kernal.bin.
