ramips: add support for ZyXEL WAP6805 (Altibox WiFi+)
Hardware -------- SoC: MediaTek MT7621ST WiFi: MediaTek MT7603 Quantenna QT3840BC Flash: 128M NAND RAM: 64M LED: Dual colour red and green BTN: Reset WPS Eth: 4 x 10/100/1000 connected to MT7621 internal switch MT7621 RGMII port connected to Quantenna module GPIO: Power/reset of Quantenna module Quantenna module ---------------- The Quantenna QT3840BC (or QV840) is a separate SoC running another Linux installation. It is mounted on a wide mini-PCIe form factor module, but is connected to the RGMII port of the MT7621. It loads both a second uboot stage and an os image from the MT7621 using tftp. The module is configured using Quantenna specific RPC calls over IP, using 802.1q over the RGMII link to support multiple SSIDs. There is no support for using this module as a WiFi device in OpenWrt. A package with basic firmware and management tools is being prepared. Serial ports ------------ Two serial ports with headers: RRJ1 - 115200 8N1 - Connected to the Quantenna console J1 - 57600 8N1 - Connected to the MT7621 console Both share pinout with many other Zyxel/Mitrastar devices: 1 - NC (VDD) 2 - TX 3 - RX 4 - NC (no pin) 5 - GND Dual system partitions ---------------------- The vendor firmware and boot loader use a dual partition scheme storing a counter in the header of each partition. The partition with the highest number will be selected for boot. OpenWrt does not support this scheme and will always use the first OS partition. It will reset both counters to zero the first time sysupgrade is run, making sure the first partition is selected by the boot loader. Installation from vendor firmware --------------------------------- 1. Run a DHCP server. The WAP6805 is configured as a client device and does not have a default static IP address. Make a note of which address it is assigned 2. tftp the OpenWrt initramfs-kernel.bin image to this address. Wait for the WAP6805 to reboot. 3. ssh to the OpenWrt initramfs system on 192.168.1.1. Make a backup of all mtd partitions now. The last used OEM image is still present in either "Kernel" or "Kernel2" at this point, and can be restored later if you save a copy. 4. sysupgrade to the OpenWrt sysupgrade.bin image. Installation from U-Boot ------------------------ This requires serial console access 1. Copy the OpenWrt initramfs-kernel.bin image as "ras.bin" to your tftp server directory. Configure the server address as 192.168.0.33/24 2. Hit ESC when the message "Hit ESC key to stop autoboot" appears 3. Type "ATGU" + Enter, and then "2" immediately after pressing enter. 4. Answer Y to the question "Erase Linux in Flash then burn new one. Are you sure?", and answer the address/filename questions. Defaults: Input device IP (192.168.0.2) Input server IP (192.168.0.33) Input Linux Kernel filename ("ras.bin") 5. Wait until after you see the message "Done!" and power cycle the device. It will hang after flashing. 6. Continue with step 3 and 4 from the vendor firmware procedure. Notes on the WAP6805 U-Boot --------------------------- The bootloader has been modified with both ZyXELs zyloader and the device specific dual partition scheme. These changes appear to have broken a few things. The zyloader shell claims to support a number of ZyXEL AT commands, but not all of them work. The image selection scheme is unreliable and inconsistent. A limited U-Boot menu is available - and used by the above U-Boot install procedure. But direct booting into an uploaded image does not work, neither with ram nor with flash. Flashing works, but requires a hard reset after it is finished. Reverting to OEM firmware ------------------------- The OEM firmware can be restored by using mtd write from OpenWrt, flashing it to the "Kernel" partition. E.g. ssh root@192.168.1.1 "mtd -r -e Kernel write - Kernel" < oem.bin OEM firmwares for the WAP6805 are not avaible for public download, so a backup of the original installation is required. See above. Alternatively, firmware for the WAP6806 (Armor X1) may be used. This is exactly the same hardware. But the branding features do obviously differ. LED controller -------------- Hardware implementation is unknown. The dual-color LED is controlled by 3 GPIOs: 4: red 7: blinking green 13: green Enabling both red and green makes the LED appear yellow. The boot loader enables hardware blinking, causing the green LED to blink slowly on power-on, until the OpenWrt boot mode starts a faster software blink.
