From e752fc1ff9d1d4f50a32155dd714dcde4b070bd4 Mon Sep 17 00:00:00 2001 From: Lech Perczak Date: Fri, 29 May 2020 20:50:05 +0200 Subject: ath79: add support for TP-Link TL-WR802N V1 and V2 Specification: - SoC: Qualcomm Atheros QCA9533 (560 MHz, MIPS 24Kc) - RAM: 32 MiB - Storage: 4 MiB of Flash on board - Wireless: Built into QCA9533 (Honey Bee), PHY modes b/g/n - Ethernet: 1x100M (port0) Installation through OEM Web Interface: - Connect to TL-WR802N by Ethernet or Wi-Fi - Go to web interface: [V1] http://192.168.0.1 [V2] http://192.168.0.254 Default user is "admin" & password is "admin". On V2, there is no DHCP server running by default, so remember to set IP manually. - Go to "System Tools -> Firmware Upgrade" - Browse for firmware: [V1] "*.factory.bin" [V2] "*.factory-us.bin" or "*.factory-eu.bin" for eu model Web interface may complain if filename is too long. In such case, rename .bin to something shorter. - Click upgrade Installation through tftp: Note: T_OUT, T_IN and GND on the board must be connected to USB TTL Serial Configuration 115200 8n1 - Boot the TL-WR802N - When "Autobooting in 1 seconds" appears type "tpl" followed by enter - Connect to the board Ethernet port (IPADDR: 192.168.1.1, ServerIP: 192.168.1.10) - tftpboot 0x80000000 - Record the result of "printenv bootcmd" - Enter "erase +0x3c0000" (e.g erase 0x9f020000 +0x3c0000) - Enter "cp.b 0x80000000 0x3c0000" (e.g cp.b 0x80000000 0x9f020000 0x3c0000) - Enter "bootm " (e.g bootm 0x9f020000) Notes: When porting from ar71xx target to ath79, I found out that on V2, reset button is on GPIO12 and active low, instead of GPIO11 and active high. By cross-flashing V1 firmware to V2, I confirmed the same is true for V1. Also according to manual of V1, this one also has green LED instead of blue - both of those issues were fixed accordingly. The MAC address assignment has been checked with OEM firmware.
