Opening the case

Note: This will void your warranty!

  • Unscrew the 2 screws on one of sides (no need to unscrew both front and back sides)
  • Get the pcb and pull it

The PCB have processor module and main board module.

Serial

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

The board contains 2 serial ports. To connect console-port, look at the CPU-module PCB photo, and find JP1 (unsoldered 16-pin connector). This connector contains serial port pins:

PIN Description
1 GND
2 ?
3 RXD
4 TXD
5…16 ?

Look at "Photo of top side of CPU-module PCB" for soldering. At photos, the cords already soldered to needed pins. The speed is 115200 8N1.

The second serial port is connected to voltage level converter, and used for RS-485 connection to the camera.

Debricking

NOTE, the root password of the original firmware is unknown, but You have access to U-Boot.

Bootloader Info

Before booting kernel, the board boots 3 Bootloaders:

  1. RBL (rom bootloader), it selects from what device to boot. The board try to boot from nand, but if it fails, it will try to boot from SD/MMC.
  2. UBL (user bootloader), it's first 16 KiB at the nand memory, this bootloader needed to met RBL requirements.
  3. U-Boot. Almost 1 MiB allocated for this bootloader (include nvram).

You have full access to U-Boot. To enter into U-Boot menu, just press any key when board started, here is output and "help" cmd:

Hardware mods

As a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!

SD/MMC LED Mod

TODO The LED may be soldered to PCB to inform users, that SD/MMC card is busy. Just connect resistor 300 Ohm … 1 KOhm into R66 place, and LED into LED1 place.

USB Mod

TODO Both USB-modes are supported (OTG and HOST), but need to add resistors/jumpers to CPU-board, due USB mode must be selected by pin-configuration. Parts needed in main board: USB1, T3, R79, R76, R71, R78, R70, R68.

Video-Output Mod

Find JP2 connector (white) at the top side of main board. It's composite-video output. It works fine as-is, but it would be a good idea to solder operational amplifier, to protect dm365 chip from static electricity.

PIN VALUE
1 VIDEO
2 GND

Source Code

  1. D-Link GPL code for DVS-310-1 B1. Total: 1.6 GiB (contains DVSDK 2.0 components, no sources for AVServer application and TI-modules). It's very old, but usable to determine what gpio pins connected to i/o lines:
  2. Gateworks Rincon developed Openwrt patches for DM6446 (very similar CPU):
    • They also creates Luci-web module for H264 streaming to multicast.
    • ti-modules package contains sources for proprietary part for using H264 and MJPEG hardware encoders.
    • They creates patches to kernel to support TVP5150 chip, that used in DVS-310-1
  3. LeopardBoard SDK (RidgeRun SDK): registration needed
    • Using the same kernel as backfire (2.6.32)
    • integrated with DVSDK to produce hardware-accelerated H264/MJPEG, MP3/AAC codec's for gstreamer (same as gateworks rincon).
  4. TI DVSDK: wiki page, for download, you need to register at TI and accept license agreement. This step always needed, if You need hardware-accelerated codecs.
    • Contains source code for kernel modules, that utilize DSP functionality (codecs, scalers, face detection, etc.)
    • Latest version (DVSDK_4.0) also using linux-2.6.32 as kernel.

Notes

This device selling at various markets (especially at security survillance), the price for this device: ~250$ (June 2011)

Driver Description Status Connemt
tvp5150 Video capture Done based on this info
cq93vc Audio capture Done 8KHz - ok, 16KHz - don't works
ds1302 RTC Done
mii ethernet Partially done finished in newer patch
nand Flash memory Done the mtd table would be changed
DSP Audio/Video codecs Not done Need to modify DVSDK makefile to use Linaro compiler instead of CodeSourcery

2.6.33 kernel patches

ToDo:

  1. Use TI-tools to compile DSP-related code
  2. Make gstreamer works at target platform.
  3. Test luci video streaming application (decoding/encoding).
