X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cb3cd526948af3f69da1af18e035177a0a8f58e3;p=openwrt%2Fstaging%2Fthess.git

ath79: add support for devolo WiFi pro 1750x

Hardware
--------
CPU:   Qualcomm Atheros QCA9558
RAM:   128M DDR2
FLASH: 16MiB
ETH:   1x Atheros AR8035 (PoE in)
WiFi2: QCA9558 3T3R
WiFi5: QCA9880 3T3R
BTN:   1x Reset
LED:   1x LED Power (non-controllable)
       1x LED Status (internal)
       1x LED LAN (controlled by PHY)
       1x LED WLAN
BEEP:  1x GPIO attached piezo beeper
UART:  3.3V GND TX RX (115200-N-8) (3.3V is square pad)
       Header is located next to external-LED header.

Installation
------------
Make sure you set a password for the root user as prompted on first
setup!

1. Upload OpenWRT sysupgrade image via SSH to the device.
Use /tmp as the destination folder on the device.
User is root, password the one set in the web interface.

2. Install OpenWRT with

> sysupgrade -n -F /tmp/<openwrt-image-name>
