CPU Bootloader

The SoC has an embedded bootloader that can be used when there is no bootloader

at the flash chip. Press the reset button while powering up the device:

done

Pres the X key at the serial console. Then send via XMODEM your recovery bootloader: recovery.img

Now you cand send via XMODEM a full backup, and flash it.

Flash Backup

Using this phython script we can make a full backup without desoldering the flash chip:
https://github.com/danitool/bootloader-dump-tools/blob/master/rt63365tool.py

  1. Power off the device.
  2. Conect the USB UART adapter in your computer to the serial port at the router (only TX, RX and GND).
  3. Execute this command (tested on ARCHLinux OS):
    python2 rt63365tool.py --read=hg532-fullflash_backup.bin --addr=0xB0000000 --size=0x800000 --block=0x10000
  4. Power up the device, the backup should start automatically.

Flash backup (Orange ISP): hg532s-flash_backup.zip

Restore the flash backup

  1. Power off the device.
  2. Conect the USB UART adapter in your computer to the serial port at
    the router (only TX, RX and GND). Open the serial software console.
  3. Conect the ethernet cable from your computer to the device.
    Set a static IP on your computer compatible with 192.168.1.1, i.e: 192.168.1.33.
  4. Power up the device and inmediatelly press a key on the serial console.
    It should stop at the bootloader CLI with the symbol:
    bldr>
  5. Send the image via TFTP: on your computer execute
    tftp 192.168.1.1 -m binary -c put fullflash.bin
  6. Flash the image (the received image should be stored at 0x80020000):
    flash 0 80020000 800000
  7. Power cycle the device

Third party firmwares

The TP-LINK TD-W8968 v2 has identical hardware, but a firmware with more features.

It can be installed by flashing a full flash backup from the TD-W8968 v2.

We only need to replace the WIFi calibration data and the MAC hardware address

by the ones used in our device.

You can ommit steps 3 to 4 if you aren't worried about having your own MAC/calibration data.

But it's always recommendable making a flash backup, step 1
  • Tune the Tplink image (procedure made in a Linux OS desktop PC):
  1. Make a full flash backup on the HG532s as described above. Rename it to hg532sfull.bin
  2. Download the Tplink flash backup:
    TD-W8968v2-flashbackup-mod.zip.
    Uncompress the file and rename it to tplinkfull.bin.
  3. Now we can insert the wifi calibration data from our device in the tplink file. Execute this command:
    dd if=hg532sfull.bin bs=1 skip=$((0x11000)) count=512 | dd of=tplinkfull.bin bs=1 seek=$((0x7f0000)) conv=notrunc
  4. Insert the MAC addres of our HG532s in the tplink file:
    echo -ne \\x00\\x11\\x22\\x33\\x44\\x55 | dd of=tplinkfull.bin bs=1 seek=$((0x7DF100)) conv=notrunc
    In this example the MAC was 00:11:22:33:44:55

a new busybox with more utilities among other nice features. You can go to the original Tplink firmware after
flashing if you feel more comfortable. The default serial console and telnet user/password are admin:1234,
whereas the default web interace is admin:admin.
