ramips: add support for MikroTik RouterBOARD 760iGS (hEX S) This patch adds support for the MikroTik RouterBOARD 760iGS router. It is similar to the already supported RouterBOARD 750Gr3. The 760iGS device features an added SFP cage, and passive PoE out on port 5 compared to the RB750Gr3. https://mikrotik.com/product/hex_s Specifications: - SoC: MediaTek MT7621A - CPU: 880MHz - Flash: 16 MB - RAM: 256 MB - Ethernet: 5x 10/100/1000 Mbps - SFP cage - USB port - microSD slot Unsupported: - Beeper (requires PWM driver) - ZT2046Q (ADS7846 compatible) on SPI as slave 1 (CS1) The linux driver requires an interrupt, and pendown GPIO These are unknown, and not needed with the touchscreen only used for temperature and voltage monitoring. ads7846 hwmon: temp0 is degrees Celsius temp1 is voltage * 32 GPIOs: - 07: input passive PoE out (lan5) compatible (Mikrotik) device connected - 17: output passive PoE out (lan5) switch Installation through RouterBoot follows the usual MikroTik method https://openwrt.org/toh/mikrotik/common To boot to intramfs image in RAM: 1. Setup TFTP server to serve intramfs image. 2. Plug Ethernet cable into WAN port. 3. Unplug power, hold reset button and plug power in. Wait (~25 seconds) for beep and then release reset button. The SFP LED will be lit in RouterBoot, but will not be lit in OpenWRT. 4. Wait for a minute. Router should be running OpenWrt, check by plugging in to port 2-5 and going to 192.168.1.1. To install OpenWrt to flash: 1. Follow steps above to boot intramfs image in RAM. 2. Flash the sysupgrade.bin image with web interface or sysupgrade. 3. Once the router reboots you will be running OpenWrt from flash. OEM firmware differences: - RouterOS assigns a different MAC address for each port - The first address (E01 on the sticker) is used for wan (ether1 in OEM). - The next address is used for lan2. - The last address (E06 on the sticker) is used for sfp.
