From 9dd4ba3d7ed56413399b1e36f810813c1dcf7473 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Thu, 4 Jun 2020 20:59:13 +0200 Subject: ath79: add support for TP-Link EAP245-v3 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit TP-Link EAP245 v3 is an AC1750 (802.11ac Wave-2) ceiling mount access point. UART access (for debricking) requires non-trivial soldering. Specifications: * SoC: QCA9563 (CPU/DDR/AHB @ 775/650/258 MHz) * RAM: 128MiB * Flash: 16MiB SPI-NOR * Wireless 2.4GHz (SoC): b/g/n 3x3 * Wireless 5GHz (QCA9982): a/n/ac 3x3 with MU-MIMO * Ethernet (QCA8337N switch): 2× 1GbE, ETH1 (802.3at PoE) and ETH2 * Green and amber status LEDs * Reset switch (GPIO, available for failsafe) Flashing instructions: All recent firmware versions (latest is 2.20.0), can disable firmware signature verification and use a padded firmware file to flash OpenWrt: * ssh into target device and run `cliclientd stopcs` * upload factory image via web interface The stopcs-method is supported from firmware version 2.3.0. Earlier versions need to be upgraded to a newer stock version before flashing OpenWrt. Factory images for these devices are RSA signed by TP-Link. While the signature verification can be disabled, the factory image still needs to have a (fake) 1024 bit signature added to pass file checks. Debricking instructions: You can recover using u-boot via the serial port: * Serial port is available from J3 (1:TX, 2:RX, 3:GND, 4:3.3V) * Bridge R237 to connect RX, located next to J3 * Bridge R225 to connect TX, located inside can on back-side of board * Serial port is 115200 baud, 8n1, interrupt u-boot by holding ctrl+B * Upload initramfs with tftp and upgrade via OpenWrt Device mac addresses: Stock firmware has the same mac address for 2.4GHz wireless and ethernet, 5GHz is incremented by one. The base mac address is stored in the 'default-mac' partition (offset 0x90000) at an offset of 8 bytes. ART blobs contain no mac addresses.
