From 8d9c1087e4d07d625a9fef61d5dce71d850732ae Mon Sep 17 00:00:00 2001 From: David Bauer Date: Tue, 14 Apr 2020 03:58:37 +0200 Subject: ath79: add support for 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. 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.
