From 82618062cf7ed6b40d2c52c6f6b96364888ffda6 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Thu, 21 Jun 2018 14:24:59 +0200 Subject: ipq40xx: add support for the ZyXEL NBG6617 This patch adds support for ZyXEL NBG6617 Hardware highlights: SOC: IPQ4018 / QCA Dakota CPU: Quad-Core ARMv7 Processor rev 5 (v7l) Cortex-A7 DRAM: 256 MiB DDR3L-1600/1866 Nanya NT5CC128M16IP-DI @ 537 MHz NOR: 32 MiB Macronix MX25L25635F ETH: Qualcomm Atheros QCA8075 Gigabit Switch (4 x LAN, 1 x WAN) USB: 1 x 3.0 (via Synopsys DesignWare DWC3 controller in the SoC) WLAN1: Qualcomm Atheros QCA4018 2.4GHz 802.11bgn 2:2x2 WLAN2: Qualcomm Atheros QCA4018 5GHz 802.11a/n/ac 2:2x2 INPUT: RESET Button, WIFI/Rfkill Togglebutton, WPS Button LEDS: Power, WAN, LAN 1-4, WLAN 2.4GHz, WLAN 5GHz, USB, WPS Serial: WARNING: The serial port needs a TTL/RS-232 3.3v level converter! The Serial setting is 115200-8-N-1. The 1x4 .1" header comes pre-soldered. Pinout: 1. 3v3 (Label printed on the PCB), 2. RX, 3. GND, 4. TX first install / debricking / restore stock: 0. Have a PC running a tftp-server @ 192.168.1.99/24 1. connect the PC to any LAN-Ports 2. put the openwrt...-factory.bin (or V1.00(ABCT.X).bin for stock) file into the tftp-server root directory and rename it to just "ras.bin". 3. power-cycle the router and hold down the the WPS button (for 30sek) 4. Wait (for a long time - the serial console provides some progress reports. The u-boot says it best: "Please be patient". 5. Once the power LED starts to flashes slowly and the USB + WPS LEDs flashes fast at the same time. You have to reboot the device and it should then come right up. Installation via Web-UI: 0. Connect a PC to the powered-on router. It will assign your PC a IP-address via DHCP 1. Access the Web-UI at 192.168.1.1 (Default Passwort: 1234) 2. Go to the "Expert Mode" 3. Under "Maintenance", select "Firmware-Upgrade" 4. Upload the OpenWRT factory image 5. Wait for the Device to finish. It will reboot into OpenWRT without any additional actions needed. To open the ZyXEL NBG6617: 0. remove the four rubber feet glued on the backside 1. remove the four philips screws and pry open the top cover (by applying force between the plastic top housing from the backside/lan-port side) Access the real u-boot shell: ZyXEL uses a proprietary loader/shell on top of u-boot: "ZyXEL zloader v2.02" When the device is starting up, the user can enter the the loader shell by simply pressing a key within the 3 seconds once the following string appears on the serial console: | Hit any key to stop autoboot: 3 The user is then dropped to a locked shell. |NBG6617> HELP |ATEN x[,y] set BootExtension Debug Flag (y=password) |ATSE x show the seed of password generator |ATSH dump manufacturer related data in ROM |ATRT [x,y,z,u] RAM read/write test (x=level, y=start addr, z=end addr, u=iterations) |ATGO boot up whole system |ATUR x upgrade RAS image (filename) |NBG6617> In order to escape/unlock a password challenge has to be passed.
