ar71xx: add support for Fritz!WLAN Repeater 450E
This commit adds support for the AVM Fritz!WLAN Repeater 450E
SOC: Qualcomm QCA9556 (Scorpion) 560MHz MIPS74Kc
RAM: 64MB Zentel A3R12E40CBF DDR2
FLASH: 16MiB Winbond W25Q128 SPI NOR
WLAN1: QCA9556 2.4 GHz 802.11b/g/n 3x3
INPUT: WPS button
LED: Power, WiFi, LAN, RSSI indicator
Serial: 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
- 2.4GHz WiFi (correct MAC)
- Installation via EVA bootloader
- OpenWRT sysupgrade
- Buttons
- Most LEDs
Not working:
- 2 RSSI LEDs
AVM used for RSSI{0,1} two of the Ethernet PHYs LEDs which they
control over MDIO. Our driver doesn't expose these LEDs as GPIOs.
While it is possible to implement this feature, it would require an
additional kernel patch for a minor functionality.
Installation via EVA:
In the first seconds after Power is connected, the bootloader will
listen for FTP connections on 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.
You need to powercycle the Device afterwards to boot OpenWRT.
