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 ALFA Network AP121FE The AP121FE is a slightly modified version of already supported AP121F model (added to ar71xx in 0c6165d21a and to ath79 in 334bbc5198). The differences in compare to AP121F: - no micro SD card reader - USB data lines are included in Type-A plug - USB bus switched to device/peripheral mode (permanently, in bootstrap) Other than that, specifications are the same: - Atheros AR9331 - 400/400/200 MHz (CPU/DDR/AHB) - 64 MB of RAM (DDR1) - 16 MB of flash (SPI NOR) - 1x 10/100 Mbps Ethernet - 1T1R 2.4 GHz Wi-Fi, up to 15 dBm - 1x IPEX/U.FL connector, internal PCB antenna - 3x LED, 1x button, 1x switch - 4-pin UART header on PCB (2 mm pitch) - USB 2.0 Type-A plug (power and data) Flash instruction (under U-Boot web recovery mode): 1. Configure PC with static IP 192.168.1.2/24. 2. Connect PC with RJ45 port, press the reset button, power up device, wait for first blink of all LEDs (indicates network setup), then keep button for 3 following blinks and release it. 3. Open 192.168.1.1 address in your browser and upload sysupgrade image. |
