From a32c06f44d6340fd25d1eb276f62b8494de9f462 Mon Sep 17 00:00:00 2001 From: INAGAKI Hiroshi Date: Wed, 16 May 2018 21:42:48 +0900 Subject: [PATCH] ramips: add support for I-O DATA WN-GX300GR I-O DATA WN-GX300GR is a 2.4 GHz band 11n router, based on MediaTek MT7621S. Specification: - MT7621S (1-Core, 2-Threads) - 64 MB of RAM - 8 MB of Flash (SPI) - 2T2R 2.4 GHz - 5x 10/100/1000 Mbps Ethernet - 2x LEDs, 4x keys (2x buttons, 1x slide switch) - UART header on PCB - Vcc, GND, TX, RX from ethernet port side - baudrate: 115200 bps (U-Boot, OpenWrt) Flash instruction using initramfs image: 1. Connect serial cable to UART header 2. Rename OpenWrt initramfs image for WN-GX300GR to "uImageWN-GX300GR" and place it in the TFTP directory 3. Set the IP address of the computer to 192.168.99.8, connect to the LAN port of WN-GX300GR, and start the TFTP server on the computer 4. Connect power cable to WN-GX300GR and turn on the router 5. Press "1" key on the serial console to interrupt boot process on U-Boot, press Enter key 3 times and start firmware download via TFTP 6. WN-GX300GR downloads initramfs image and boot with it 7. On the initramfs image, execute "mtd erase firmware" to erase stock firmware and execute sysupgrade with sysupgrade image for WN-GX300GR 8. Wait ~150 seconds to complete flasing Signed-off-by: INAGAKI Hiroshi --- .../ramips/base-files/etc/board.d/01_leds | 1 + .../ramips/base-files/etc/board.d/02_network | 4 + target/linux/ramips/base-files/etc/diag.sh | 1 + .../ramips/base-files/lib/upgrade/platform.sh | 1 + target/linux/ramips/dts/WN-GX300GR.dts | 156 ++++++++++++++++++ target/linux/ramips/image/mt7621.mk | 8 + 6 files changed, 171 insertions(+) create mode 100644 target/linux/ramips/dts/WN-GX300GR.dts diff --git a/target/linux/ramips/base-files/etc/board.d/01_leds b/target/linux/ramips/base-files/etc/board.d/01_leds index ae5ac77b5e..183ab2904f 100755 --- a/target/linux/ramips/base-files/etc/board.d/01_leds +++ b/target/linux/ramips/base-files/etc/board.d/01_leds @@ -168,6 +168,7 @@ dlink,dwr-921-c1) ucidef_set_led_default "sigstrength" "Signal Strength" "$boardname:green:sigstrength" "0" ;;
