From 44cd32d764fe1daed3b6d0595530df0c4d1c3464 Mon Sep 17 00:00:00 2001 From: Roland Reinl Date: Sun, 1 Oct 2023 11:25:40 +0200 Subject: [PATCH] mediatek: Add support for TP-Link EAP225v5 Device specification: - MT7629 with 16MB NOR flash W25Q128 and 128 MB DDR3 RAM. - MT7761N and MT7762N wireless chips (currenlty no driver in OpenWrt available) - WiFi is NOT working on this device - Dual core but second CPU doesn't seem to work (Error message during boot: "CPU1: failed to come online") There are two similar merge requests for similar devices with the same issues: - https://github.com/openwrt/openwrt/pull/12286 - https://github.com/openwrt/openwrt/pull/5084 UART interface is next to the reset button, pinout: - 1: TX (the pin with the arrow marker) - 2: RX - 3: GND - 4: VCC UART settings: 115200,8n1, 3.3V U-Boot menu can be entered by pressing Ctrl+B during startup. Booting initramfs: - Set your computers IP adress to 192.168.1.110 - Run a TFTP server providing the initramfs image - Power on the AP, press Ctrl+B to get to the U-Boot menu - Select "1. System Load Linux to SDRAM via TFTP" - Update kernel file name, input server IP and input device IP (if they deviate from the defaults) - After booting, create a backup of all partitions, especially for kernel and root_fs. They are required for reverting back to stock firmware - The sysupgrade image can be flashed now MAC adresses: - LAN and 2.4GHz use the same MAC (the one printed on the device) - 5GHz WiFi MAC is LAN MAC + 1 GPIOs: - GPIO 21 is the reset pin (low active) - GPIO 55 is for the green LED (active high) - GPIO 56 is for the yellow/amber LED (active high) Signed-off-by: Roland Reinl --- .../mediatek/dts/mt7629-tplink_eap225-v5.dts | 188 ++++++++++++++++++ target/linux/mediatek/image/mt7629.mk | 9 + .../mt7629/base-files/etc/board.d/02_network | 3 +- 3 files changed, 199 insertions(+), 1 deletion(-) create mode 100644 target/linux/mediatek/dts/mt7629-tplink_eap225-v5.dts diff --git a/target/linux/mediatek/dts/mt7629-tplink_eap225-v5.dts b/target/linux/mediatek/dts/mt7629-tplink_eap225-v5.dts new file mode 100644 index 0000000000..52e22541fa --- /dev/null +++ b/target/linux/mediatek/dts/mt7629-tplink_eap225-v5.dts @@ -0,0 +1,188 @@ +// SPDX-License-Identifier: GPL-2.0 + +/dts-v1/;
