→ Install OpenWrt (generic explanation)

It is recommend to use Linux. This installation process is not written for Windows.

  1. Make a backup of the original firmware, so you are prepared if something goes wrong (Backup).
  2. Boot u-boot from RAM and then flash u-boot into flash memory (U-Boot).
  3. With the flashed u-boot you can then flash OpenWrt into flash memory (OpenWrt).
  4. With the working OpenWrt you can then upgrade to the OpenWrt version 19.07.4 (Upgrade).

The device was not thoroughly tested with OpenWrt. Do not follow this information here if you do not have a backup device, as you could end up with a bricked device. You have been warned.

Backup

Please backup your original firmware!

Tools

brntool

I will use brntool to explain the backup here. As an alternative you could use brndumper to save the original firmware (If you prefer a graphical interface, brndumper is probably better for you).

According to the readme of brntool:

A successful flash block read will output '.' while a botched one (a byte or more gets lost in the serial port) will output '!' and retry. Even so, unless in a hurry, I'd recommend to at least dump twice and compare the dumps, just to be on the safe side.

A memory dump of the original firmware is done in about one hour.
You should dump the original firmware at least twice (as recommended by the author of brntool), so the whole backup process takes about two hours.

  1. Download the small python script https://raw.githubusercontent.com/rvalles/brntool/master/brntool.py
  2. Install the python package pyserial https://pyserial.readthedocs.io/en/latest/pyserial.html#installation
  3. Enter the “Administrator Mode” of the DANUBE bootloader (OEM bootloader) of your device
    1. Connect to the serial console connectors (Serial)
    2. Open a terminal
    3. Type: 
      screen /dev/ttyUSB0 115200
    4. Power on the device and quickly press the space bar 3 times
    5. Enter the “Administration Mode” in the DANUBE bootloader. Type exclamation mark (!)
    6. You should see something like this:
      Press Space Bar 3 times to enter command mode ...123
Yes, Enter command mode ...

    7. Close your serial connection by pressing the key combination in the terminal: [CTRL] + [A] then [K] then [Y] to confirm exit
  4. With the serial connection closed, you can now dump the original firmware
    1. Type:
      python2 brntool.py --read=ARV752DPW_whole.dump --addr=0xB0000000 --verbose --size=0x800000
    • 0xB0000000 - starting address of flash memory

    1. Now you should have a file called “ARV752DPW_whole.dump”
    2. Restart the device and enter the “Administrator Mode” again, so you can dump the original firmware the second time
    3. Type:
      python2 brntool.py --read=ARV752DPW_whole2.dump --addr=0xB0000000 --verbose --size=0x800000
    4. Now you should have a file called “ARV752DPW_whole2.dump”
    5. List both files. Type:
      ls -l ARV752DPW_whole*.dump

      You should see two files listed, if this is not the case please rerun the backup process 

      **Example output:**
-rw-r--r--. 1 root root 8388608 12. Feb 23:32 ARV752DPW_whole2.dump
-rw-r--r--. 1 root root 8388608 13. Feb 00:58 ARV752DPW_whole.dump
    6. Check if the files have any difference. Type:
      diff ARV752DPW_whole.dump ARV752DPW_whole2.dump

      You should see no output, if this is not the case please rerun the backup process

    7. Compare both files. Type:
      cmp ARV752DPW_whole.dump ARV752DPW_whole2.dump

      You should see no output, if this is not the case please rerun the backup process

    8. Finally we generate the md5 hash of both files. Type:
      md5sum ARV752DPW_whole*

      You should see the hashes of both files, please compare them. If they are not the same, please perform the backup process again 

      **Example output:**
b245fc54da24db7a81bb915e968453f8  ARV752DPW_whole2.dump
b245fc54da24db7a81bb915e968453f8  ARV752DPW_whole.dump
    9. If everything is ok you will end with 2 identical files
  5. You now have a full backup of the original firmware

U-Boot Bootloader

There are two ways to get the u-boot bootloader running on the device. Each approach requires different u-boot images. All downloads (LINK).

  • Temporary u-boot bootloader (LINK) - required image: brnboot-uboot.bin - temporarily load u-boot bootloader as second stage bootloader into memory
  • Permanent u-boot bootloader (LINK) - required image: flash-uboot.bin - load u-boot permanently on the flash memory as the main bootloader

These images are copies of older images, because at the moment the images of the snapshot repo don't work and bricking the device.

My guess is that the flash memory for the u-boot bootloader is too small for the new u-boot images from the snapshot repo. — Yemtex 2020/11/28

1. Temporary u-boot

Temporarily load u-boot bootloader as second stage bootloader into memory

  1. Download brnboot-uboot.bin
  2. Enter the “Administrator Mode” of the DANUBE bootloader (OEM bootloader) of your device
    1. Connect to the serial console connectors (Serial)
    2. Open a terminal
    3. Type: 
      screen /dev/ttyUSB0 115200
    4. Power on the device and quickly press the space bar 3 times
    5. To enter the “Administration Mode” in the DANUBE bootloader. Type exclamation mark (!)
    6. You should see something like this:
      Press Space Bar 3 times to enter command mode ...123
Yes, Enter command mode ...

You can hit [Ctrl] + [C] to get to the menu.

Beware, u-boot is being currently loaded only in the RAM.
Powering off your device will kill your u-boot, you will need to start again with this procedure.

2. Permanent u-boot

Use this method if you want to place the u-boot bootloader permanently on the flash memory as the main bootloader

You need a running u-boot bootloader (Use (LINK) to accomplish that)

  1. Download flash-uboot.bin
  2. Download write-to-uboot.py
  3. Check serial connection
    1. Connect to the serial console connectors (Serial)
    2. Open a terminal
    3. Type: 
      screen /dev/ttyUSB0 115200
    4. You should now see the u-boot command line (ARV752DPW # ),
      • if this is the case, you have successfully loaded the temporary u-boot bootloader
      • if not, press the [ENTER] key a few times, if that doesn't help, your temporary u-boot bootloader doesn't work. Reboot your device and try to load u-boot as temporary bootloader again (LINK)
    5. Close your serial connection by pressing the key combination in the terminal: [CTRL] + [A] then [K] then [Y] to confirm exit
  4. Transfer your image to your device via serial connection by using the downloaded python script. Type:
    python2 write-to-uboot.py --serial=/dev/ttyUSB0 --write=flash-uboot.bin --addr=0x80500000 --verbose
    • 0x80500000 - starting address of RAM

  5. The output of the executed script shows what to do next:
    **Example output**
File successfully written. You should run command 'crc32 80500000 00010000' on the modem and the result must be 223ed699.
  6. Open your u-boot command line. Type: 
    screen /dev/ttyUSB0 115200
  7. Check the crc32 checksum 
    **Please use the right parameters**
crc32 80500000 00010000
    • if the checksum is not the same, the uploaded image is corrupted. Please try to upload it again.

  8. Unprotect the sector where the u-boot config is being stored. Type: 
    protect off 0xb0010000 0xb001FFFF
  9. Erase the flash memory. Type: 
    erase 0xb0000000 0xb001FFFF
  10. Copy the uploaded flash-uboot.bin from RAM to flash memory. Type: 
    cp.b 0x80500000 0xb0000000 10000
    • 0x80500000 is the RAM address, where I've uploaded my file

  11. Protect the config sector. Type: 
    protect on 0xb0010000 0xb001FFFF
  12. Reboot device and hope for the best :). Type: 
    reset

!!PANIC!! I flashed u-boot, now TFTP/HTTP in u-boot is not working anymore
Calm down, you can upload everything you need via your serial connection by using this python script: write-to-uboot.py

UART u-boot

This method is intended for rescue purposes (bricked device). Use this method with absolute caution.


  1. Download u-boot.asc
  2. Connect to the serial console connectors (Serial)
  3. Open a terminal
  4. Type: 
    screen /dev/ttyUSB0 115200
  5. Short-circuit R80 and bring +3.3 V on the left side of R65 (see picture), while powering on the device.
  6. You should see something like this:
    ROM VER: 1.0.3
CFG 04
Read EEPROMX
 X
UART
  1. Close your serial connection by pressing the key combination in the terminal: [CTRL] + [A] then [K] then [Y] to confirm exit
  2. Jumpstart your device by sending the downloaded u-boot file via serial connnection to your device. Type:
    cat u-boot.asc > /dev/ttyUSB0
  3. After the file is transmitted, u-boot bootloader should load.

Beware, u-boot is being currently loaded only in the RAM.
Powering off your device will kill your u-boot, you will need to start again with this procedure.

To restore u-boot completely, upload u-boot via your serial connection and write it back to flash memory using the u-boot instructions above (LINK)

OpenWrt

There are two ways to get OpenWrt running on the device. Each approach requires different OpenWrt images. All downloads (LINK).

  1. We boot OpenWrt to test if it's working
  2. We flash an old working version of OpenWrt permanantly onto the device
  3. And with the linux shell of this OpenWrt we upgrade to the 19.07.4 version of OpenWrt

    • if the checksum is not the same, the uploaded image is corrupted. Please try to upload it again.

  11. Erase the flash memory. Type: 
    erase 0xB0020000 +0x$filesize$
  12. Copy the uploaded initramfs-kernel.bin from RAM to flash memory. Type: 
    cp.b 0x80500000 0xB0020000 0x$filesize$
    • 0xB0020000 - starting address for firmware (see LINK)

  13. Check if uploaded image is recognized as OpenWrt (If the image has no header, there is no output). Type: 
    iminfo 0xB0020000
  14. Boot uploaded image. Type: 
    bootm ${kernel_addr} ${bootargs}

2. Flash OpenWrt

Please test if OpenWrt is working by just booting it (see LINK) before flashing OpenWrt permanantly onto the flash memory

  1. Download squashfs.image

3. Upgrade OpenWrt

Before upgrading to 19.07.4 OpenWrt make sure that your current OpenWrt works.
You need a running OpenWrt (Use LINK to accomplish that)

Using Upgrading OpenWrt firmware using CLI

  1. Download squashfs-sysupgrade.bin
  2. Change IP of your host device (laptop / pc) to 192.168.1.5
  3. Connect via LAN to device (Use one of the four LAN ports (yellow))
  4. SSH to device using IP 192.168.1.1
    • If password is prompted, use serial console to change password. Type: <code>passwd</code>

  5. Change directory to tmp. Type: 
    cd /tmp
    • /tmp directory is stored in the device RAM

  6. Check free memory is available. Type: 
    free
    • Proceed, if “free Mem” is the size of your firmware file + some extra mem (at least twice the size of your firmware file is perfect).

  7. Exit ssh session. Type: 
    exit
  8. Upload squashfs-sysupgrade.bin image via scp (ssh file transfer). Type: 
    scp openwrt-19.07.4-lantiq-xway-arcadyan_arv752dpw-squashfs-sysupgrade.bin root@192.168.1.1:/tmp
  9. Generate the md5 checksum of the squashfs-sysupgrade.bin image on your host device (laptop / pc)
  10. Generate md5 checksum of uploaded file by opening a new ssh session. Type: 
    md5sum openwrt-19.07.4-lantiq-xway-arcadyan_arv752dpw-squashfs-sysupgrade.bin
  11. Compare both md5 checksums
    • If the checksum mismatches: Redo the firmware download, if the mismatch remains, ask for help in the “Installing and Using OpenWrt” Forum

  12. Execute sysupgrade on device. Type: 
    sysupgrade -n -v /tmp/*.bin
    • Ignore the “TRX header not found” and “Error fixing up TRX header” errors. These errors are not relevant according to Forum

  13. Wait until the router comes back online.
  14. Your device is now running on version 19.07.4 of OpenWrt

Additional information: 

uboot-..._brn meant to be loaded from brnboot (stock bootloader) as a 2nd stage bootloader into memory
uboot-..._nor meant to be flashed into the unit as main bootloader (at 0xB0000000 +$filesize)
uboot-..._ram meant to be uploaded via UART by serial if nor_bootloader got broken, for rescue purposes

u-boot images of snapshots repo are broken at the moment (December 2020), here is a backup of working images:

Building

I am new to openwrt and want to build the firmware for this device. There are no build instructions yet so I will add them here while I am experimenting with build. --- JPT1 2016/04/29 15:16

  • Follow this https://wiki.openwrt.org/doc/howto/buildroot.exigence but probably fetch 15.5 branch: git clone git:git.openwrt.org/15.05/openwrt.git
  • when running make menuconfig select the following:
    • Target System: lantiq
    • Target Profile: Easybox 802 - ARV752DPW
    • optional: usb-2.0 drivers, printer and usb-storage?
    • optional: filesystem drivers?
    • Ralink RT2860 PCI is reported not to work in 15.5 (see above). wireless drivers are already selected, firmware is available. so this seems to be a runtime problem. maybe this helps in trouble shooting: https://wireless.wiki.kernel.org/en/users/drivers/rt2800pci
    • Boot Loaders: uboot-lantiq-arv752dpw_brn or other formats depending on how you are gonna install the firmware (see above)
  • make
  • find your firmware images in bin/lantiq
