From e7b3414fd58992f7aaed5425617695ed354a84ea Mon Sep 17 00:00:00 2001 From: Alexey Bartenev <41exey@proton.me> Date: Mon, 7 Aug 2023 02:18:23 -0400 Subject: [PATCH] ramips: add support for SNR-CPE-W4N-MT router MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit General specification: - SoC Type: MediaTek MT7620N (580MHz) - ROM: 8 MB SPI-NOR (W25Q64FV) - RAM: 64 MB DDR (M13S5121632A) - Switch: MediaTek MT7530 - Ethernet: 5 ports - 5×100MbE (WAN, LAN1-4) - Wireless 2.4 GHz: b/g/n - Buttons: 1 button (RESET) - Bootloader: U-Boot 1.1.3, MediaTek U-Boot: 5.0.0.5 - Power: 12 VDC, 1.0 A Flash by the native uploader in 2 stages: 1. Use the native uploader to flash an initramfs image. Choose openwrt-ramips-mt7620-snr_cpe-w4n-mt-initramfs-kernel.bin file by "Administration/Management/Firmware update/Choose File" in vendor's web interface (ip: 192.168.1.10, login: Admin, password: Admin). Wait ~160 seconds. 2. Flash a sysupgrade image via the initramfs image. Choose openwrt-ramips-mt7620-snr_cpe-w4n-mt-squashfs-sysupgrade.bin file by "System/Backup/Flash Firmware/Flash image..." in LuCI web interface (ip: 192.168.1.1, login: root, no password). Wait ~240 seconds. Flash by U-Boot TFTP method: 1. Configure your PC with IP 192.168.1.131 2. Set up TFTP server and put the openwrt-ramips-mt7620-snr_cpe-w4n-mt-squashfs-sysupgrade.bin image on your PC 3. Connect serial port (57600 8N1) and turn on the router. Then interrupt "U-Boot Boot Menu" by hitting 2 key (select "2: Load system code then write to Flash via TFTP."). Press Y key when show "Warning!! Erase Linux in Flash then burn new one. Are you sure? (Y/N)" Input device IP (192.168.1.1) ==:192.168.1.1 Input server IP (192.168.1.131) ==:192.168.1.131 Input Linux Kernel filename () ==: openwrt-ramips-mt7620-snr_cpe-w4n-mt-squashfs-sysupgrade.bin 3. Wait ~120 seconds to complete flashing Signed-off-by: Alexey Bartenev <41exey@proton.me> (cherry picked from commit 7796c2d7ef5ff465c8c75ee294b0b5fb3165f4b9) [Fix merging conflict] Signed-off-by: Alexey Bartenev <41exey@proton.me> --- package/boot/uboot-envtools/files/ramips | 5 + .../ramips/dts/mt7620n_snr_cpe-w4n-mt.dts | 122 ++++++++++++++++++ target/linux/ramips/image/mt7620.mk | 11 ++ .../mt7620/base-files/etc/board.d/01_leds | 5 + .../mt7620/base-files/etc/board.d/02_network | 6 + 5 files changed, 149 insertions(+) create mode 100644 target/linux/ramips/dts/mt7620n_snr_cpe-w4n-mt.dts diff --git a/package/boot/uboot-envtools/files/ramips b/package/boot/uboot-envtools/files/ramips index 01fa0e1966..933d3629c5 100644 --- a/package/boot/uboot-envtools/files/ramips +++ b/package/boot/uboot-envtools/files/ramips @@ -63,6 +63,11 @@ linksys,ea8100-v2|\ mts,wg430223) ubootenv_add_uci_config "/dev/mtd1" "0x0" "0x1000" "0x20000" ;;
