D-Link DIR-320 H/W Ver.: B1

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 onto it! See 4/32 warning 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 OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

Please check out the article flash.layout. It contains an example and a couple of explanations.

OEM easy installation

  1. Get the firmware from here
  2. Plug off power cable
  3. Press and hold “reset” button
  4. Plug on power cable, wait for 15 seconds
  5. Setup your network manually: IP 192.168.0.2 MASK 255.255.255.0
  6. Enter web interface 192.168.0.1
  7. Chose your .bin file and submit reflashing
  8. Setup your network to get options by DHCP
  9. Wait until power led will light

Specific Configuration

Interfaces

The default network configuration is:

Interface Name Description Default configuration
br-lan LAN & WiFi 192.168.1.1/24
vlan0 (eth0.0) LAN ports (1 to 4) None
vlan1 (eth0.1) WAN port DHCP
wl0 WiFi Disabled

Switch Ports (for VLANs)

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the CPU of router. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.

Port Switch port
Internet (WAN) 4
LAN 1 3
LAN 2 2
LAN 3 1
LAN 4 0

Main PCB

Serial

→ port.serial general information about the serial port, serial port cable, etc.

How to connect to the Serial Port of DIR-320NRU:

Pins from top to bottom:

  1. TX
  2. Ground
  3. VCC (3.3V)
  4. key
  5. RX

Serial console jack don't soldered on plant, place of jack are empty.
Warning: console port are serial 3.3 V, if you want connect router to PC RS232, it is need to use serial 3.3V to 5V converter.
Note: Serial port speed is 57600 bod

JTAG

→ port.jtag general information about the JTAG port, JTAG cable, etc.

How to connect to the JTAG Port of this specific device:

Debricking

Take solderer into hands :) and connect to console port on the board of the router using serial 3.3V to serial 5V converter. Next insert power jack into router and wait for U-boot:

Please choose the operation: 
   1: Load system code to SDRAM via TFTP. 
   2: Load system code then write to Flash via TFTP. 
   3: Boot system code via Flash (default).
   4: Entr boot command line interface.
   7: Load Boot Loader code then write to Flash via Serial. 
   9: Load Boot Loader code then write to Flash via TFTP.

Press “4” and next you may type command for bootloader.

Notes

Run custom script with OEM firmware

  • Official firmware contain bug in the config parser: inline code execution are allowed. Confiuration files placed in the directory /etc/default (simlink of /tmp/etc/default). You may telnet to router and insert your script call using `/path/to/script.sh` into some config file, next save your changes to NVRAM. Look a shell code example in the russian article.

Original part of /etc/default/config.json 

"dmz": {
"enable": true,
"ip": "192.168.0.2"
},

Modified part of /etc/default/config.json: 

"dmz": {
"enable": true,
"ip": "`/etc/default/shaper.sh`"
},
echo Set DMZ Host to 9.9.9.9 via WebIF and run me again!
echo Use /etc/default/DMZ.txt to set DMZ Host IP
sed -i s/9.9.9.9/"\`\/etc\/default\/shaper.sh\`"/g /etc/default/config.json
saveconfig

A program /usr/sbin/saveconfig writes configuration data to NVRAM. At boot a program /usr/sbin/loadconfig load a NVRAM and write config files into /etc/default/.
