ramips: add support for MikroTik RouterBOARD RBM11g
This commit adds support for the MikroTik RouterBOARD RBM11g. =Hardware= The RBM11g is a mt7621 based device featuring one GbE port and one miniPCIe slot with a sim card socket and USB 2.0. ==Switch== The single onboard Ethernet port is connected the CPU directly. The internal switch of the mt7621 SoC is disabled. ==Flash== The device has one spi nor flash chip. It is a 128 Mbit winbond 25Q128FVS connected to CS0. ==PCIe== The board features a single miniPCIe slot. It has a dedicated mini SIM socket and a USB 2.0 port. Power to the miniPCIe slot is controlled via GPIO9. ==USB== There are no external USB ports. ==Power== The board can accept both, passive PoE and external power via a 2.1 mm barrel jack (center-positive). The input voltage range is 11-32 V. ==Serial port== The device does have an onboard UART on an unpopulated header next to the flash chip: GND: pin 2 TX: pin 7 RX: pin 6 Settings: 115200, 8N1 See below illustration for positioning of the header. 0 = screw hole * = some pin T = TX pin R = RX pin G = GND pin Pinout: +--------------- |O | __ | / \ | \__/ | | | | +---+ | |RAM| | +--+ | | | |**| <- unpopulated header with UART | |*T| +---+ | |R*| +--------+ | |**| | | | |G*| | CPU | | +--+ | | | +--+ | | | | | +--------+ | +--+ <- flash chip |O | +-----+ | | | |+--+ | | || | | | +--------------------- =Installation= To install an OpenWRT image to the device two components must be built: 1. A openwrt initramfs image 2. A openwrt sysupgrade image ===initramfs & sysupgrade image=== Select target devices "Mikrotik RBM11G" in openwrt menuconfig and build the images. This will create the images "openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin" and "openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin" in the output directory. ==Installing== **Make sure to back up your RouterOS license in case you do ever want to go back to RouterOS using "/system license output" and back up the created license file.** When rebooted the board will try booting via ethernet first. If your board does not boot via ethernet automatically you will have to attach to the serial port and set ethernet as boot device within RouterBOOT. 1. Set up a dhcp server that points the bootfile to tftp server serving the "openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin" initramfs image 2. Connect to ethernet port on board 3. Power on the board 4. Wait for OpenWrt to boot Right now OpenWrt will be running with a SSH server listening. Now OpenWrt must be flashed to the devices flash: 1. Copy "openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin" to the device using scp. 2. Write openwrt to flash using "sysupgrade openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin" Once the flashing completes the board will reboot. Disconnect from the devices ethernet port or stop the DHCP/TFTP server to prevent the device from booting via ethernet again. The device should now boot straight to OpenWrt.
