Flashing[]

DD-WRT[]

The WRT310N accepts only the mini, standard, and VPN builds; no other versions are supported on this device. Do not even attempt to flash it with the micro (does not support gigabit ethernet so switch will not work for LAN ports) or mega-build (requires 8MB of flash, WRT310N only has 4MB), you will end up with a non-responding router or worse, a very expensive brick! Flashing a virgin WRT310N with the default Linksys firmware will require a special "trailed" mini-build to be flashed first. You should use a build from the BS Broadcom folder 12874 for the initial flash. The name of this file specifically is "dd-wrt.v24_mini_wrt310n.bin". You may proceed to flash it with a generic STD or VPN build next. Remember to do the 30/30/30 Hard Reset after every successful flash. It is absolutely essential.

The proper process for flashing is:

  1. Read Note 1 of the peacock announcement http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
  2. Read Note 3 of the peacock announcement
  3. Download svn 12874 dd-wrt.v24_mini_wrt310n.bin ftp://dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/09-08-09-r12874/broadcom/dd-wrt.v24_mini_wrt310n.bin
  4. Do a HARD reset on your router. You will not get a password renewal page as you have stock linksys firmware on the router still.
  5. Plug a cable into the lan port of the router and your computer, and disable any wireless to the computer. Disable all firewalls and virus protection. (Setting your computer to a static IP should not be required)
  6. Set your browser to 192.168.1.1. This will open up the linksys webgui
  7. Enter the username admin and password admin
  8. Go to the administration tab. Click on firmware upgrade.
  9. BROWSE to the dd-wrt.v24_mini_wrt310n.bin file you downloaded.
  10. Click on the upgrade button and WAIT for the upgrade successful message.
  11. Power cycle your router. (very important) WAIT until you can relogin at 192.168.1.1
  12. Do a PROPER HARD 30-30-30 reset on your router (very important) WAIT until you can login at 192.168.1.1
  13. Click on any tab. Reset your username/password by TYPING in a new username/password
  14. Configure your router

You can now upgrade to any generic dd-wrt build except Mega and Micro. Be sure to always do a hard reset prior to flashing another build, do a power cycle followed by another hard reset after flashing, and NEVER re-use a configuration file from a previous build or another router. Reconfigure from scratch. Recovery information available in this thread.

Upgrading[]

If dd-wrt is already on the router follow these instructions. If stock firmware is on the router follow the flashing instructions.

  1. Check for recommended builds here first.
  2. Set your computer to a static IP of 192.168.1.7. (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
  3. Hard reset or 30/30/30 (If the router supports it, if not, reset to defults in the GUI) prior to flashing. Wait. Check for password page on re-login and change password.
  4. Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
  5. Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
  6. Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
  7. Wait for the lights to return to normal usually about 2 minutes.
  8. Hard reset or 30/30/30 again (If the router supports it, if not, reset to defults in the GUI). Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
  9. Once configured set your computer back to autoIP and autoDNS.

Important1: This Hard reset or 30/30/30 works fine for Asus router, but you do have to power cycle after the reset.

Important2: After you flash the firmware, and before you do the hard reset, the router will be building some nvram settings. YOU MUST WAIT FOR THIS TO FINISH PRIOR TO DOING ANYTHING WITH THE ROUTER INCLUDING A HARD RESET. Usually, you can tell when this process is completed by the WAN light coming on, but it does take several minutes. Go have a beer. There are starting to be more and more people who BRICK their routers by not waiting until the nvram is rebuilt, PRIOR to doing a hard reset. YOU NEED TO WAIT!

JTAG Recovery[]

To perform JTAG recovery, you'll need to solder a JTAG header onto the appropriate pads on the router's board. Debricking a router via JTAG is a common procedure with generally the same steps:

  1. Solder on JTAG header to the correct place on the board
  2. Connect the JTAG cable's signal wires to the correct pins
  3. Run software to clear the router's nvram and kernel storage areas in flash memory
  4. Re-flash the router with a new kernel (firmware)

To complete the procedure, you'll need:

  1. Screwdriver with Torx bits & flathead bit (for prying)
  2. Soldering iron
  3. Lead free electronics solder
  4. JTAG Cable (I used a Xilinx Parallel Cable III DLC5, but any supported by tjtag will do)
  5. JTAG Software
  6. A kernel to re-flash the device with

I recommend tjtag. Source Code can be found here: https://github.com/oxplot/tjtag-pi. You may also want to try zjtag or one of the forks listed here

For the wrt310n, you need a mini build of dd-wrt with a special "310N" header for the first flash. I had success using the custom build that redhawk0 posted in this forum thread, but you may have good results with any mini brainslayer build after March 2009. The official wrt310n dd-wrt wiki page recommends this build: BrainSlayer-V24-preSP2-2010-08-12-10-r14929-dd-wrt.v24_mini_wrt310n.bin

Soldering on a JTAG header[]
Wrt310n jtag header

To solder on a JTAG header to the wrt310n, you first need to open up the plastic chassis using a torx tamper-resistant security bit (#T-9H). Next, gently pry open the plastic chassis near the left and right sides of the router. There should be 2 plastic clips on either side of the top clamshell piece that you'll need to release. There are also 2 plastic clips near the front of the bottom clamshell piece that need to be released. After the plastic clamshell chassis is opened, you should see 2 potential pin header locations on the lower right of the board. The one to the left with the through-holes is NOT the correct place to solder the JTAG header.

The one to the right with copper pads is the CORRECT one (See image near bottom right where pin header is soldered)

Connecting the JTAG Cable[]
Wrt310n JTAG pinout top PCB

In order to connect the JTAG cable you will have to identify the number of each pin. The correct pinout is listed above. To identify the pin numbering, look at the numbers printed on the PCB next to the pins. You should see some numbers like '1', '11', on top and '2', '12' on the bottom. Pin numbering starts from 1 on the top and continues left to right, top to bottom. This pattern works out such that the odd numbers are all on the top, and even pin numbers are all on the bottom of the PCB.

Wrt310n JTAG pinout bottom PCB

Here is a photo of the top of some JTAG flying wires connected to the wrt310n's JTAG header which has been soldered to the top and bottom of the PCB. As you can see, pins 3, 5, 7, and 9 are the necessary JTAG data pins to connect like this: (TDI = 3, TDO = 5, TMS = 7, TCK = 9). On the bottom of the board, the pinout shows many ground pins. I have used pin 6 for GND.

Installing tjtag[]

After connecting the JTAG cable, you will need to make sure you have the tjtag software installed. If you don't have a compiled binary executable for tjtag (binaries can be found here), you'll need to download and compile the source code for tjtag like this:

git clone https://github.com/oxplot/tjtag-pi.git
cd tjtag-pi
make     # for standard linux
make pi  # for Raspberry Pi
CFLAGS='-D WINDOWS_VERSION' make  # for Windows
CFLAGS='-D __FreeBSD__' make      # for FreeBSD

You should end up with a binary executable called 'tjtag' ('tjtag.exe' for Windows). You'll use this tool to clear the flash memory. If you are using a parallel port cable on linux, make sure to load the kernel module if it was not autoloaded. Sometimes the lp printer driver will grab the parallel port and prevent tjtag from accessing it. You may have to unload the lp driver first, and reload the parallel port drivers:

sudo rmmod lp  ## This should prevent tjtag error: "Failed to lock /dev/parport0: No such device or address"
## Remove drivers
for driver in ppdev parport_pc parport; do sudo modprobe -r $driver; done
## Re-insert drivers
for driver in ppdev parport_pc parport; do sudo modprobe -i $driver; done
Detecting Hardware via JTAG[]

To run a quick test to see if your router and flash chip are detected, run: ./tjtag -probeonly /noreset. The router's microprocessor chip will sometimes halt and prevent the detection from working. (You will see the probeonly command hang at "Issuing Processor / Peripheral Reset ... Skipped"). Just retry a couple times, or try doing a 30/30/30 reset on the router and it should work. If you see error message "Failed to open /dev/parport0: Permission denied", you need to run the command as root with sudo. You'll see output like this:


$ sudo ./tjtag -probeonly /noreset

Clearing Flash Memory via JTAG[]

You will need to reset both the kernel and nvram from flash memory.

To reset:

  • kernel - run: ./tjtag -erase:kernel /noreset
  • nvram - run: ./tjtag -erase:nvram /noreset

If tjtag does not detect the flash chip, you might need to pass the correct flag depending on the flash chip you have. Different revisions of the wrt310n have been built using different flash chips. To identify your chip, look on the bottom of the board. It should be marked by a couple dots (See this forum thread for help identifying the location). The chip manufacturer and ID should be printed on it. Some common chips found in wrt310n are:

/fc:19 ............. K8D3216UBC  2Mx16 BotB     (4MB)

/fc:102 ............. EON EN29LV320 2Mx16 BotB   (4MB)

The output from erasing kernel & nvram should look like this:

$ sudo ./tjtag -erase:kernel  /fc:102 /noreset

Installing New Firmware/Kernel[]

To install new firmware & kernel, you will need to tftp the mini build of dd-wrt to the router. Upon booting after a 30/30/30 reset, the router will accept a tftp upload of the firmware. The important part here is to get the timing right, have a kernel with appropriate wrt310n header, and WAIT at least 2-3 minutes AFTER a successful flash for nvram settings to be rebuilt. Failing to wait for nvram to be rebuilt will usually re-brick the router and you will have to start over from clearing the nvram & kernel via JTAG.

Screenshot 2014-09-17 19.28

To install the new firmware, the procedure is as follows:

  • Plug a cable into the LAN port of the router and your computer, and disable any wireless to the computer. Disable all firewalls and virus protection.
  • Set your computer to a static IP (see image)

Use these settings:

192.168.1.10  ip
255.255.255.0 subnet
192.168.1.1   gateway
192.168.1.1   dns
  • Perform 30/30/30 reset
  • Unplug router
  • Start pinging router continuously
  • Plug in router while holding the reset button
  • Immediately tftp the firmware after the first successful ping
    • Timing is important! If you keep getting failed pings indefinitely or see an error from tftp like "Transfer timed out.", you are missing the upload window.
    • If you are having problems getting timing right running commands manually, I suggest using this script (change firmware name according to the filename you saved it as, run from same directory):
#!/bin/bash
## dd-wrt router tftp flashing script for *nix platforms
## To use:
 ##  - Make sure you are connected via LAN cable to router
##  - Press reset button on router & hold for 30 seconds
##  - Unplug router while holding reset button for 30 seconds
##  - Start this script and watch pings fail
##  - Plug in router while still holding reset button for 30 seconds
##  - Release reset
##  - With any luck a ping succeeds and tftp uploads the firmware
router_ip=192.168.1.1
firmware=dd-wrt.v24_mini_wrt310N-redhawk0.bin

if [[ $OSTYPE = *darwin* ]]; then
     ping_args='-W 5'
elif [[ $OSTYPE = *linux-gnu ]]; then
     ping_args='-w 130'
else
  ping_args=''
   fi
   
   result=1
   while [ $result -ne 0 ]; do
     ping -c 1 $ping_args $router_ip
  result=$?
   done && tftp $router_ip <<-EOF
     connect $router_ip
  binary
     put $firmware
   EOF
## Windows batch script to upload firmware
## Make sure you have tftp installed via Control Panel first
## http://avtech.com/Support/index.php?action=kb&article=108
 ## To use:
 ##  - Make sure you are connected via LAN cable to router
##  - Press reset button on router & hold for 30 seconds
##  - Unplug router while holding reset button for 30 seconds
##  - Start this script and watch pings fail
##  - Plug in router while still holding reset button for 30 seconds
##  - Release reset
##  - With any luck a ping succeeds and tftp uploads the firmware
SET router_ip=192.168.1.1
SET firmware=dd-wrt.v24_mini_wrt310N-redhawk0.bin

:loop
  ping -n 1 -w 5 %router_ip%
  IF NOT %ERRORLEVEL%==0 (
      goto loop
  )
  tftp -i %router_ip% put %firmware%
  • If this step worked, you should see a success message from tftp like:

"Sent 2936864 bytes in 5.4 seconds"

  • WAIT AT LEAST 2-3 minutes while the new kernel is booted and nvram settings are built! Do NOT power off the router until this time has elapsed. This step is important for the firmware to stick!
  • Go to the router's web interface at http://192.168.1.1

If it worked, you should see the Router Management page and password reset dialog for dd-wrt.

If it didn't work, try unplugging router, starting tftp script, and trying again!

  • After you have flashed the router with the special mini build, you can now use the dd-wrt web interface (Administration -> Firmware Upgrade) to upload the dd-wrt.v24_std_generic build.

Changing from Passive Cooling to Active Cooling[]

Raptor2213 noticed that after uploading DD-WRT firmware that his first-gen WRT-310N kept overheating. Possible solutions include:

  1. Strap a 120mm fan on the bottom of the router (make sure to use feet to keep it off the ground).
  2. Mod your WRT-310N to use an active cooler.
