FAQ

Q:Does the X820 support Trim?

  • The X820 does not support TRIM,the current X820 version only UASP supported. For LINUX and USB2.0, UASP is better.

Q: Don't detect HDD/SDD?

  • This is a complicated question, but we can check it from these points. Please refer to How to check the X820

Q: With a hard drive installed, could you eleminate the need for a micro sd card and boot straight from drive?

Q: What is a recommended HDD for this board?

  • Basically it can support all the 2.5-inch HDD with SATA 2 or STATA 3 interface.

Q: Why can't boot from the SSD or HDD?

  • Customer Feedback 1: I have followed the same steps you provided and my ssd is not able to boot. I have tried again with a normal sata hard drive and it works fine. My original ssd (Patriot Burst 240gb) draws too much power. Thus, do not boot.

Q:Can you stack the module with itself? is the usb cable and bridge crossover?

  • Theoretically, you can stack the X820 module to use by USB cable.

But you need to solve the problem of how to power them, if you stack them together, it may need more power. Actually we do not test on how to stack them together, hope to get your understanding!

Q: Why the voltage warnings shows on my Pi? Customer feeback: The board works as advertised with the 4a power supply they recommend but seems to lie really close to the voltage limit. I get a number of voltage warnings while using until I stopped using the KVM switch (which had a separate power supply) and just used a USB keyboard. Outside of that, assembled just fine and was able to configure a SSD 2.5 drive without issue.

  • To a large extent, we doubt that voltage warnings maybe caused by the power supply.
  • Our power supply has an idling output voltage of 5.2V , even when the working current reaches 4A, the output voltage will be around 4.9V, this is the reason why the Raspberry Pi system does not have undervoltage.
  • So we suggest that you can measure the output voltage of your power supply when under load your device. Please test directly the voltage value between GND and 5V PIN.
  • We found that many power supplies on the market are known as 5V 4A output, but when use this power adapter at high current output , the voltage often drops very badly, with only about 4.7V or lower than 4.7V.

Q: What is the pinout for the PWR Switch?

Q: How to do if I don't like the blue light on the power switch?

  • It is ok to disable the blue light on the power switch, you just need to pull out the white cable. Please refer to the picture.

Q: Does the X820 Power off switch work when the Pi is powered by USB (or PoE)?

  • A: The X820 Power off switch cannot work when the Pi is powered by USB (or PoE).

Some Tips

How to boot from a USB Mass storage device on a raspberry pi 3

This tutorial explains how to boot your Raspberry Pi 3 from a USB mass storage device such as a flash drive or USB hard disk. Be warned that this feature is experimental and does not work with all USB mass storage devices. See this blog post from Gordon Hollingworth for an explanation of why some USB mass storage devices don't work, as well as some background information.

Program USB Boot Mode

Before a Raspberry Pi 3 will boot from a mass storage device, it needs to be booted from an SD card with a config option to enable USB boot mode. This will set a bit in the OTP (One Time Programmable) memory in the Raspberry Pi SoC that will enable booting from a USB mass storage device. Once this bit has been set, the SD card is no longer required. Note that any change you make to the OTP is permanent and cannot be undone.

You can use any SD card running Raspbian or Raspbian Lite to program the OTP bit. If you don't have such an SD card then you can install Raspbian or Raspbian Lite in the normal way - see installing images.

  • First, prepare the /boot directory with up to date boot files:
sudo apt-get update
sudo apt-get upgrade

The above step is not required if you use the 2017-04-10 release of Raspbian / Raspbian Lite or later, (PS: use or update the last Raspbian version is always recommend)

  • Then enable USB boot mode with this code:
echo program_usb_boot_mode=1 | sudo tee -a /boot/config.txt
sudo reboot

This adds program_usb_boot_mode=1 to the end of /boot/config.txt. Reboot the Raspberry Pi with sudo reboot, then check that the OTP has been programmed with:

vcgencmd otp_dump | grep 17:
17:3020000a

Ensure the output 0x3020000a is shown. If it is not, then the OTP bit has not been successfully programmed.

If you wish, you can remove the program_usb_boot_mode line from config.txt, so that if you put the SD card in another Raspberry Pi, it won't program USB boot mode. Make sure there is no blank line at the end of config.txt. You can edit config.txt using the nano editor using the command sudo nano /boot/config.txt, for example.

Prepare the operating system image

Starting with the 2017-04-10 release of Raspbian you can install a working Raspbian system to a USB mass storage device by copying the operating system image directly onto your USB device, in the same way that you would for an SD card. To perform this step, follow the instructions HERE, remembering to select the drive that corresponds to your USB mass storage device.

Once you have finished imaging your USB mass storage device, remove it from your computer and insert it into your Raspberry Pi 3.

[Boot your Raspberry Pi 3 from the USB mass storage device]

Attach the USB mass storage device to your Raspberry Pi 3 and power it up. After between five and ten seconds the Raspberry Pi 3 should begin booting, and display the rainbow splash screen on an attached screen.

Please refer to here: USB mass storage device boot

I have a 5v 3A power supply connected directly to the pi. The x820 is powered via usb. I have no power running from the gpio to the x820. I am not sure if there are some settings that need changing to enable this functionality, but I am not able to get the power button to function on my x820 board. The power button has a red led when the pi is on, but when pressing the button the pi does not respond in any way. Any suggestions? Any aid is appreciated.

I believe I’m having a power supply issue. It is 5v and 4amp. The case purchased was the X820 can you direct me to a power supply that you believe is of good quality on the Internet or within your store for purchase. I have the device powering up without any issue at all. I do believe it’s under powered at this point, and I purchased a faulty or less than satisfactory power supply. Thank you in advance for your consideration of the question and your assistance.

Hi,Sorry, we don't sell DC5V power supply now, it is recommended that you buy a high-quality DC 5V power supply. If use a poor quality power supply, the SSD/HDD may not be identified or be damaged.

Or you can consider using X735 power management board, which supports Type C 5V and DC6V~30V,and you can use our Type C5V 4A or DC12V power supply.

I am using X820 (v3.0) with RPi 3b+ running Raspbian + Supervised HA installation (fresh installation, all SW latest versions). Unfortunately the system gets stuck when I reboot it (sudo reboot) - it goes down but it does not come up automatically. I have to manually power it off and on using the button.

X820 is jumpered to Auto ON position. Are any additional settings required for reboot to work? Any other insights you can offer?

Here is the additional information you requested:

The system is installed on SSD. This SSD with the same SW stack and RPi3b+ but using a different Sata to USB adaptor (instead of X820) works fine and supports reboot.

As you requested, I also tried a setup with just OS without Supervised HA - same problem on X820, reboot does not work.

Please note that I am using the latest version of 64-bit raspbian OS. I tried both full version and the lite version (without desktop) - the same problem exists when using X820.

Appreciate you looking into this issue, let me know if you need additional info.

Hi,

To answer your questions:

I usually power the system using MeanWell GST25A05 5V 4A power supply.

1) When I plug the power supply into X820 and RPi is powered from X820 via 2-PIN power cable (and also connected via USB of course) - reboot does not work.

2) When I plug the power supply (the same MeanWell) into RPi and X820 gets the power only from RPi via USB (2-PIN power cable is not used) - reboot works fine. However, there are 2 problems with this configuration i) power button on X820 does not work ii) RPi periodically reports an undervoltage warning (hwmon hwmon1: Undervoltage detected). This does not happen when I use a different SATA to USB dongle instead of X820 or when I power the system via X820.

Please let me know if you want me to run an additional experiment

Thanks for you info.

1)This is related to your SSD timing.

2)Undervoltage---please check your power supply, and you can measure the voltage of PIN2, 4;

3)Only powering the X820 via USB ,It can reboot, and yes, switch does not work

4)If you have an HDD, it is recommended to use the HDD to test it, can reboot normally.

As the RPi 4 Network adapter and USB ports have been re-arranged and using the USB connector would line up (approx) with the Network port on the RPi 4, it won't work with the instructions provided. However, (NOTE: I haven't tried this) the USB interface should work (at USB3 interface speed) with the Raspberry pi 4, but the blue cable would need to be used (assuming that the connections are the same as the short USB connector), rather than the USB-USB link connector.

A modification would be to either adjust the USB link for the RPi 4, or make an alternative USB link, then the same board could be used with either RPi, just need a different USB-USB connector (or a short USB cable).

I like the case, but I think there could be some improvements. Here is my list. I have checked these items with others, and they say they would be likely to buy the case if some or all of these were implemented: - make it taller so there isn't an issue with hats - make the top cover plastic. That would allow onboard GPS units to work, as well as improve WiFi and Bluetooth performance - make the shutdown so that it shuts the PI down, then the power.

- make a slot for GPIO access.

For a future version, please make it possible to control Raspberry PI for a clean shutdown command when the power button is pushed, similar to how it works with a PC or laptop. It should be easy to add a connection to the GPIO and then a very small script to run to shutdown the PI, then alert the power board to shut down.

Just pushing the power button and removing power from the PI without shutdown can damage the SD card or the disk.

How can I have the board(s) auto power on after a power fail? Switching the header from “auto off” to “auto on” does not seem to work.

Hello, Thanks for all you feedback,it was found out that there a little capacitor on the X820 board to be changed, then it will slove the problem. The auto on problem will be solved soon, when the updated products released, we will update information. You can pay attention to Geekworm official website : geekworm.com to know more about product update. Best regards,

For auto power ON, add a 1uF capacitor between the red wire (+) and the black wire plugged on the button. Respect the polarity of your capacitor if necessary (tantalum ou electrolytic).
