From 3f8c5d547677e7f4e450e88379c03448b8f53b1d Mon Sep 17 00:00:00 2001 From: David Bauer Date: Sat, 18 Aug 2018 18:30:46 +0200 Subject: ath79: 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 The USB port doesn't work. Both Root Hubs are detected as having 0 Ports: [ 3.670807] kmodloader: loading kernel modules from /etc/modules-boot.d/* [ 3.723267] usbcore: registered new interface driver usbfs [ 3.729058] usbcore: registered new interface driver hub [ 3.734616] usbcore: registered new device driver usb [ 3.744181] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver [ 3.758357] SCSI subsystem initialized [ 3.766026] ehci-platform: EHCI generic platform driver [ 3.771548] ehci-platform ehci-platform.0: EHCI Host Controller [ 3.777708] ehci-platform ehci-platform.0: new USB bus registered, assigned bus number 1 [ 3.788169] ehci-platform ehci-platform.0: irq 48, io mem 0x1b000000 [ 3.816647] ehci-platform ehci-platform.0: USB 2.0 started, EHCI 0.00 [ 3.824001] hub 1-0:1.0: USB hub found [ 3.828219] hub 1-0:1.0: config failed, hub doesn't have any ports!

(err -19) [ 3.908928] usbcore: registered new interface driver usb-storage [ 3.915634] kmodloader: done loading kernel modules from /etc/modules-boot.d/* A few words about the shift-register: AVM used a trick to control the shift-register for the LEDs with only 2 pins, SERCLK and MOSI. Q7S, normally used for daisy-chaining multiple shift-registers, pulls the latch, moving the shift register-state to the storage register. It also pulls down MR (normally pulled up) to clear the storage register, so the latch gets released and will not be pulled by the remaining bits in the shift-register. Shift register is all-zero after this. For that we need to make sure output 7 is set to high on driver probe. We accomplish this by using gpio-hogging. 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.
