From b6a4c674684585902ee07a4ba7c89d988d633650 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Tue, 24 Apr 2018 19:52:13 +0200 Subject: ar71xx: add support for Fritz!Box 4020 This commit adds support for the AVM Fritz!Box 4020 WiFi-router. SoC: Qualcomm Atheros QCA9561 (Dragonfly) 750MHz RAM: Winbond W971GG6KB-25 FLASH: Macronix MX25L12835F WiFi: QCA9561 b/g/n 3x3 450Mbit/s USB: 1x USB 2.0 IN: WPS button, WiFi button OUT: Power LED green, Internet LED green, WLAN LED green, LAN LED green, INFO LED green, INFO LED red UART: Header Next to Black metal shield Pinout is 3.3V - RX - TX - GND (Square Pad is 3.3V) The Serial setting is 115200-8-N-1. Tested and working: - Ethernet (LAN + WAN) - WiFi (correct MAC) - Installation via EVA bootloader - OpenWRT sysupgrade - Buttons - LEDs Not working: - USB port Installation via EVA: In the first seconds after Power is connected, the bootloader will listen for FTP connections on 169.254.157.1 (Might also be 192.168.178.1). Firmware can be uploaded like following: ftp> quote USER adam2 ftp> quote PASS adam2 ftp> binary ftp> debug ftp> passive ftp> quote MEDIA FLSH ftp> put openwrt-sysupgrade.bin mtd1 Note that this procedure might take up to two minutes. After transfer is complete you need to powercycle the device to boot OpenWRT.
