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 I-O DATA ETG3-R I-O DATA ETG3-R is a wired router, based on Atheros AR9342. Specification: - Atheros AR9342 - 64 MB of RAM - 8 MB of Flash - 5x 10/100/1000 Ethernet - AR8327N - 2x LEDs, 1x key - UART header on PCB - Vcc, GND, TX, RX from ethernet port side - 115200n8 Flash instruction using initramfs image: 1. Connect serial cable to UART header on ETG3-R 2. Rename OpenWrt initramfs image to "1500A8C0.img" and place it in the TFTP directory 3. Set IP address of the computer to 192.168.0.10, connect to the LAN port of ETG3-R, and start the TFTP server on the computer 4. Connect power cable to ETG3-R and turn on the router 5. Press "Enter" key when the "Hit any key to stop autoboot:" message is displayed on the console and enter the u-boot cli 6. execute following commands to change kernel address for u-boot setenv bootsf 1 setenv mtd_kernel1 "bootm 0x9f050000" saveenv 7. execute "tftpboot; bootm" command to download the initramfs image from TFTP server and boot with it 8. On the initramfs image, execute "mtd erase firmware" to erase stock firmware and execute sysupgrade with sysupgrade image for ETG3-R 9. Wait ~150 seconds to complete flashing |
