Analog video freezing on tDVR 8016e capture boards – Linux

Description 

Some Exacq hybrid systems built since 7/23/2024 and running Ubuntu 22.04 have exhibited a freeze of the analog video after running for some period of time. This is likely a result of a false-positive error state in the PCIe ASPM (Active-state Power Management).

This can be confirmed using a Terminal with the following command:

cat /var/log/kern.log | grep pcieport

The result will include lines similar to the following:

pcieport 0000:00:01.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)
pcieport 0000:00:01.0: device [8086:460d] error status/mask=00000041/00002000
pcieport 0000:00:01.0: [ 0] RxErr (First)
pcieport 0000:00:01.0: [ 6] BadTLP
pcieport 0000:00:01.0: AER: Error of this Agent is reported first
pcieport 0000:00:01.0: AER: Multiple Corrected error received: 0000:00:01.0
pcieport 0000:00:01.0: AER: can't find device of ID0008
pcieport 0000:00:01.0: AER: Multiple Corrected error received: 0000:01:00.0

Steps to Resolve

The resolution is to disable the power management mode for the PCI slots by adding a kernel boot parameter. This can be accomplished either by editing a file, or by downloading and running a script .

<br>

Method 1: Editing the /boot/refind_linux.conf file

  1. In a Terminal open the file in a text editor with sudo privileges with:
    sudo gedit /boot/refind_linux.conf

2. Edit the the highlighted lines to add “pcie_aspm=off” prior to the parentheses (“) so it matches the following:

3. Save the file and reboot the machine with:

sudo reboot

<br>

Method 2: Run the tdvrfix.sh file

  1. After logging in to the Support Portal (support.exacq.com), download the tdvrfix.sh file to the Linux Desktop.
  2. Open a Terminal and change directory to the Desktop with:
    cd Desktop
  3. Set the tdvrfix.sh file to be executable with:
    sudo chmod +x tdvrfix.sh
  4. Run the script with:
    sudo ./tdvrfix.sh
  5. Reboot the machine with:
    sudo reboot
    <br>

Confirmation

After a reboot, you can confirm the fix was applied successfully by opening a Terminal and running the following command:
cat /proc/cmdline

Confirm that “pcie_aspm=off” is in the results.

TDVR Capture Card Faulty Board

Description 

There were reports of capture cards working for upwards of 10 minutes and then would fail to produce video in live views. We have identified the issue and made the proper corrections. If this is seen on a system please follow the instructions below to identify if the board is affected. Then take the appropriate steps to set up a RMA with support to get a new card shipped for replacement.

Product 

  • Exacq Servers A and Q series.
  • exacqVision 23.03 up to 24.03

Steps to Reproduce 

If a Capture card is exhibiting these symptoms then please identify the stamp on the card seen below.

These instructions provide step by step procedure for replacing a tDVR analog card in the Q-Series / A-Series Desktop chassis.   Before changing the board, be sure that the system is unplugged from any power source and the system is placed on a clean anti-static surface. Faulty PCB board can be identified by the manufacture marking HTG on the back of the board centered near the top.  Replacement cards will have a CTX marking seen below.

Tools Required:
Phillips Screwdriver
5MM 1/4″ hexdriver

  1.  Remove top cover screws on both side of the chassis.

2. Remove two top cover screws and three card mounting bracket screws.

3. Remove top Cover and pull out tDVR card by pulling straight up.                                                                                                                           

4. Disassemble the mounting bracket from the card by removing two hex nuts.  

5. Attach the replacement card to the bracket and assemble the system by reversing the steps above.

To test the new board, boot the system and open client and verify 16 port display in live view.  

Solution

We found that a component was change during manufacturing which was found to be faulty and we have the proper components now that have been validated and working.

Who manufactures Exacq video capture boards?

Exacq designs and manufactures its own video capture boards. Current tDVR capture board models are manufactured in Canada.

Previous eDVR and sDVR capture boards, no longer manufactured, were designed by Exacq. Portions of the manufacturing process were performed by a contract manufacturer.
