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. |

ath79: add support for Ubiquiti PowerBridge M This adds support for the Ubiquiti PowerBridge M, which has the same board/LEDs as the Bullet M XM, but different case and antennas. Specifications: - AR7241 SoC @ 400 MHz - 64 MB RAM - 8 MB SPI flash - 1x 10/100 Mbps Ethernet, 24 Vdc PoE-in - Internal antenna: 25 dBi - POWER/LAN green LEDs - 4x RSSI LEDs (red, orange, green, green) - UART (115200 8N1) on PCB Flashing via WebUI: Upload the factory image via the stock firmware web UI. Attention: airOS firmware versions >= 5.6 have a new bootloader with an incompatible partition table! Please downgrade to <= 5.5 _before_ flashing OpenWrt! Refer to the device's Wiki page for further information. Flashing via TFTP: Same procedure as other Bullet M (XM) boards. - Use a pointy tool (e.g., pen cap, paper clip) and keep the reset button on the device or on the PoE supply pressed - Power on the device via PoE (keep reset button pressed) - Keep pressing until LEDs flash alternatively LED1+LED3 => LED2+LED4 => LED1+LED3, etc. - Release reset button - The device starts a TFTP server at 192.168.1.20 - Set a static IP on the computer (e.g., 192.168.1.21/24) - Upload via tftp the factory image: $ tftp 192.168.1.20 tftp> bin tftp> trace tftp> put openwrt-ath79-generic-xxxxx-ubnt_powerbridge-m-squashfs-factory.bin |
