From: Coia Prant Date: Sat, 25 Jan 2025 19:40:58 +0000 (+0800) Subject: ramips: add support for Hongdian H7920 v40 X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F17726%2Fhead;p=thirdparty%2Fopenwrt.git ramips: add support for Hongdian H7920 v40 This is an industrial 4G router equipped with OpenWrt SNAPSHOT OEM customized version WARNING: The original firmware device tree is modified from evb boards, and the device tree name is evb board. This submitted device tree is a modified version, which deletes the non-this-device parts and adds GPIO watchdog. Specification: - SoC: MediaTek MT7628NN - Flash: 16 MB - RAM: 128 MB - Power: DC 5V-36V 1.5A - Ethernet: 1x WAN [slot not install], 1x LAN (10/100 Mbps) - Wireless radio: 802.11n 2.4g-only [antenna not install] - LED: System/Power (RUN): GPIO/37 active-low Modem: GPIO/3 active-low RF (Modem Signal): GPIO/2 active-low - Button: WPS / RESET: GPIO/11 active-low - UART: 1x UART on PCB - 115200 8N1 - Serial / COM: 1X RS232/RS485 on board (GPIO/6 hi:RS485 lo:RS232) - GPIO Watchdog: GPIO/0 mode=toggle timeout=1s - Modem: 1x Built-in modem on board (Power: GPIO/4 active-high) - PCIe: 1x miniPCIe for modem [slot not install] - SIM Slots: 1x SIM Slots Issue: - Factory partition not store mac address on original firmware Flash instruction: Using SSH/Telnet: 1. Connect the board to the computer via RJ45 Ethernet 2. Login 192.168.8.1 with root password "superzxmn" (SSH Port 22, Telnet Port 5188) 3. Download openwrt firmware on the computer. 4. Use scp or sftp put firmware to board /tmp 5. Use command "mtd -r write openwrt-ramips-mt76x8-hongdian_h7920-v40-squashfs-sysupgrade.bin firmware" to flash Original Firmware Dump / More details: https://blog.gov.cooking/archives/research-hongdian-h7920-v40-and-flash.html Signed-off-by: Coia Prant Tested-by: Coia Prant Link: https://github.com/openwrt/openwrt/pull/17726 Signed-off-by: Hauke Mehrtens --- diff --git a/target/linux/ramips/dts/mt7628an_hongdian_h7920-v40.dts b/target/linux/ramips/dts/mt7628an_hongdian_h7920-v40.dts new file mode 100644 index 00000000000..76c395c382e --- /dev/null +++ b/target/linux/ramips/dts/mt7628an_hongdian_h7920-v40.dts @@ -0,0 +1,171 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "mt7628an.dtsi" + +#include +#include +#include + +/ { + compatible = "hongdian,h7920-v40", "mediatek,mt7628an-soc";
