Devi portarlo in un centro assistenza ma non so quanto siano contenti. E ricorda che i firmware degli apparati si fanno col cavo di rete e non in wireless.

6 GND RX 5 4 GND Vcc (3.3V) 3 2 GND TX 1 Some revisions might have the connector tilted by 90 degrees and placed more or less at the center of the board. Settings are 115200 8N1. NB: a short circuit between pins RX and TX at power up puts the device in a recovery mode with IP 192.168.1.1 from where a new firmware can be uploaded.

OpenWrt binaries are refused, though, because of invalid CRC. You can use a CP210x USB to UART Bridge adapter.

The advantage of the usb version is that you don't need to use battery like the old “com” version. If you use Windows you can use HyperTerminal to connect with the router. You have to use the emulated com port, set the speed of 115200 (try other speeds if you see strange caracters).

Connect the serial adapter and let the device complete the boot procedure.

You have only to wait and don't have to short-circuit RX and TX pin. At the login prompt use admin as username and password to get to the openrg Discus prompt. From the Discus prompt you can do a lot of useful things, but i've not explored it due to some lack of interest. To obtain the shell just digit system shell. Note: the first time you will not see Username, but if you write admin, router will request you the password.

If you prefer you can use an ext2 or ext3 formatted filesystem. From this file you can extract all you need to do a full restore of your device, both via jtag or via CFE. Now unmount your flash key, put the file in a safe place and reboot the Alice stopping the boot process at the bootloader prompt pressing some keys. /mnt # sync /mnt # umount backup/ /mnt # exit Returned 0 Discus> system reboot Going to reboot!

Restore original firmware. You need to setup a tftp server on some host (I can suggest to use dnsmasq for this) to serve the firmware image to the router. If you use Windows you can use tftpd32 to configure the tftpd server and the directory shared (you must connect also by lan your router and your pc).

Now just download the image for AGV2+W from, skip the jffs2 with 64k erase block as the flash use 128k block, anyway using 64k should not give much problem, just some wasted space and some errors messages. Put the choose image in the right place (see your tftp server configuration), and go to the CFE prompt. Now you have to use the flashimage command to load the openwrt image, please don't use the f command. If you configure (with command c) the host ip address you can avoid it in the flashimage argument. To get the CFE prompt you must turn on you router and when you see a countdown and you must press 'enter'. CFE> flashimage eg. Flashimage [hostip:]compressed_image_file_name That's all, the device will automaticly reboot and openwrt will be there Using dnsmasq: sudo ifconfig eth0 192.168.1.100 # by default the router use the 192.168.1.1 ip sudo dnsmasq -d --enable-tftp --tftp-root=`pwd` For example this will result in: CFE> flashimage openwrt-AGV2+W-cfe-jffs2-128k-cfe.bin Loading 192.168.1.100:openwrt-AGV2+W-cfe-jffs2-128k-cfe.bin.
