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.
