Flashing
 | NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power. |
Flashing OpenWrt
 | This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 8MB FLASH / 64MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 8/64 warning for details. This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that you will not be able to install many packages, and that you might experience crashes due to OOM situations more or less often. See OpenWrt on 8/64 devices what you can do now. |

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.
