From 66d2d037ad40dec2653c7c57946215860352423f Mon Sep 17 00:00:00 2001 From: Priit Laes Date: Fri, 8 Jan 2021 13:28:47 +0200 Subject: [PATCH] ath79: add support for COMFAST CF-E355AC v2 COMFAST CF-E355AC v2 is a ceiling mount AP with PoE support, based on Qualcomm/Atheros QCA9531 + QCA9886. Short specification: - 1x 10/100 Mbps Ethernet, with PoE support (wan/eth1) - 1x 10/100/1000 Mbps Ethernet, with PoE support (lan/eth0) - 128MB of RAM (DDR2) - 16 MB of FLASH - 2T2R 2.4 GHz, 802.11b/g/n (wlan2g) - 2T2R 5 GHz, 802.11ac/n/a, WAVE 2 (wlan5g) - built-in 4x 3 dBi antennas - output power (max): 500 mW (27 dBm) - 1x RGB LED, 1x button - separate watchdog chip via GPIO (bottom of PCB?) - UART header on PCB with proper labelling Markings on PCB: * R121QH_VER2.1 (silkscreen, bottom) * CF-WA800 (sticker, top) Initial flashing instructions: Original firmware is based on OpenWrt. a) Use sysupgrade image directly in vendor GUI. b) Or via tftp: ipaddr=192.168.1.1 serverip=192.168.1.10 bootfile="firmware.bin" c) Or possibly via u-boot's `httpd` command. MAC-address mapping follows original firmware: * eth1 (wan) is the lowest mac address (art @ 0x0) * eth0 (lan) uses eth1 + 1 (art @ 0x1002) * wlan2g (phy1) uses eth1 + 2 (art @ 0x06) * wlan5g (phy0) uses eth1 + 10 (not present in art) * unused MAC (eth1 + 3) (art @ 0x5006) Art dump (`hexdump /dev/mtd1 |grep ZZZZ`): 0000000 ZZZZ XXXX XXX0 ZZZZ XXXX XXX2 ffff ffff 0001000 0202 ZZZZ XXXX XXX1 0000 0000 0000 0000 0005000 202f bd21 0101 ZZZZ XXXX XXX3 0000 2000 Root access to original firmware (only via UART) can be achieved by making a backup of configuration from web interface. Backup contains whole `/etc` directory...
