From 84cb0f7ace73fad15e29e1d74c469b37f90b334d Mon Sep 17 00:00:00 2001 From: Robinson Wu Date: Fri, 17 Jul 2020 15:32:53 +0800 Subject: ramips: add support for JS76x8 series DEV boards This commit adds support for the Jotale JS76x8 series development boards. These devices have the following specifications: - SOC: MT7628AN/NN, MT7688AN, MT7628DAN - RAM of MT7628AN/NN and MT7688AN: 64/128/256 MB (DDR2) - RAM of MT7628DAN: 64 MB (DDR2) - FLASH:8/16/32 MB (SPI NOR) - Ethernet:3x 10/100 Mbps ethernet ports (MT76x8 built-in switch) - WIFI:1x 2T2R 2.4 GHz Wi-Fi - LEDs:1x system status green LED, 1x wifi green LED, 3x ethernet green LED - Buttons:1x reset button - 1x microSD slot - 4x USB 2.0 port - 1x mini-usb debug UART - 1x DC jack for main power (DC 5V) - 1x TTL/RS232 UART - 1x TTL/RS485 UART - 13x GPIO header - 1x audio codec(wm8960) Installation via OpenWrt: The original firmware is OpenWrt, so both LuCI and sysupgrade can be used. Installation via U-boot web: 1. Power on board with reset button pressed, release it after wifi led start blinking. 2. Setup static IP 192.168.1.123/4 on your PC. 3. Go to 192.168.1.8 in browser and upload "sysupgrade" image. Installation via U-boot tftp: 1. Connect to serial console at the mini usb, which has been connected to UART0 on board (115200 8N1) 2. Setup static IP 192.168.1.123/4 on your PC. 3. Place openwrt-firmware.bin on your PC tftp server (192.168.1.123). 3. Connect one of LAN ports on board to your PC. 4. Start terminal software (e.g. screen /dev/ttyUSB0 115200) on PC. 5. Apply power to board. 6. Interrupt U-boot with keypress of "2". 7. At u-boot prompts: Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N) Y Input device IP (192.168.1.8) ==:192.168.1.8 Input server IP (192.168.1.123) ==:192.168.1.123 Input Linux Kernel filename (root_uImage) ==:openwrt-firmware.bin 8. board will download file from tftp server, write it to flash and reboot.
