This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version (18.06 or later) onto it! Playstation 2 to pc usb gamepad converter driver.
See for details.1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See what you can do now.2) OpenWrt support for this device will end after 2019.19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See what you can do now. 6GNDRX54GNDVcc (3.3V)32GNDTX1Some 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).JTAG. 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. 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 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 flashimageeg.
