NOTE: Anything not included in model specific notes, or where a short comment couldn't be included on the notes.

If you want to upgrade using TFTP you follow these steps (as an alternative to the above install process.

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the sysupgrade command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

• Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
• Upload TRX file to LuCI
• Wait for reboot

• Login as root via SSH on 192.168.1.1
• Use the following commands to upgrade.

cd /tmp/
wget http://downloads.openwrt.org/latest/brcm-2.4/openwrt-brcm-2.4-squashfs.trx
sysupgrade /tmp/openwrt-brcm-2.4-squashfs.trx

To use kernel 2.6 and b43 driver you need to compile your image from trunk. For working image you need to run "make menuconfig" and select:

<*> kmod-b43.................................. Broadcom 43xx wireless support
<*> Remove unnecessary firmware files
(13,14,15)Core revisions to include
(LP) PHY types to include
< > kmod-b43legacy
USB Support
<*> kmod-usb-core............................................ Support for USB
<*> kmod-usb-ohci............................... Support for OHCI controllers
<*> kmod-usb-storage..................................... USB Storage support
<*> kmod-usb2................................... Support for USB2 controllers

How to connect to JTAG interface, and how to reflash the device with JTAG tools

See port.jtag for more JTAG details.

The default network configuration is:

Numbers 1-4 are Ports 1-4 as labeled on the unit, number 0 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself.

If you forgot your password, broken one of the startup scripts, firewalled yourself or corrupted the JFFS2 partition, you can get back in by using OpenWrt's failsafe mode.

• Unplug the router's power cord.
• Connect the router's LAN1 port directly to your PC.
• Configure your PC with a static IP address between 192.168.1.2 and 192.168.1.254. E. g. 192.168.1.2 (gateway and DNS is not required).
• Plug the power on and wait for the DMZ LED to light up.
• While the DMZ LED is on immediately press any button (Reset and Secure Easy Setup will work) a few times .
• If done right the DMZ LED will quickly flash 3 times every second.
• You should be able to telnet to the router at 192.168.1.1 now (no username and password)

NOTE: The root file system in failsafe mode is the SquashFS partition mounted in readonly mode. To switch to the normal writable root file system run mount_root and make any changes. Run mount_root now.

1. Forgot/lost your password and you like to set a new one

passwd

1. Forgot the routers IP address

uci get network.lan.ipaddr

1. You accidentally run 'ipkg upgrade' or filled up the flash by installing to big packages (clean the JFFS2 partition and start over)

mtd -r erase rootfs_data If you are done with failsafe mode power cycle the router and boot in normal mode.

The Dlink DIR-320 has two buttons. They are Reset and Secure Easy Setup. The buttons can be used with hotplug events. E. g. [#wifitoggle WiFi toggle].

There are 5 leds:

1. /proc/diag/led/blue
2. /proc/diag/led/red
3. /proc/diag/led/wlan
4. /proc/diag/led/diag
5. /proc/diag/led/usb

You can swich them on or off by "echo 0|1 » /proc/diag/led/blue|red|wlan|diag|usb"
