Overview

NASPi CM4-M2 is a member of NASPi family. Click GEEKWORM NAS Family to know more.


NASPi CM4-M2 is a NUC-style storage kit based on Raspberry Pi CM4 all series. It has a M2 KEY-M (NVME) SSD interface and a M2 KEY-B (NGFF) SSD interface. Its OLED screen can display some informations like CPU temperature, IP address . Also provides 3 USB 2.0 ports and 2 full-size HDMI ports, supports safe shutdown (requires installation script).


Important note:

  • Don't need to use additional SD card and power supply if you are using CM4 with emmc. When burning the system, please short the OTG on the X515 board; at the same time, use the USB-A to USB-C OTG cable (prepare it yourself) to connect to the computer.

Features

  • Model: NASPi CM4-M2
  • NUC style set-top box, compact design
  • Compatible with M2 NVME SSD or M2 SATA SSD(Only support 2280 length SSD installation)
  • Comes with an aluminum alloy heatsink C235 for CM4 passive cooling
  • Comes with a 0.96 inch OLED display
  • Support software safe shutdown & auto power on & RTC function
  • On-board blue light button switch to control power ON/OFF
  • Press button switch to turn on, hold for 1~2 seconds to reboot, hold for 3 seconds to safe shutdown, hold for more than 8 seconds to force shutdown

How to Power

Power supply: 5Vdc +/-5% , ≥4A

Recommend to use 20W 5V 4A Type-C power adapter PSU20.

How to Cool

  • Comes with a 12mm thickness aluminum alloy heatsink C235 cooler for passive cooling of Raspberry Pi CM4, which can satisfy large file copy and video playback application. And it is recommended to replace the thermal pad with CPU silicone grease for better heat dissipation.

Packing List

  • 1 x NASPi CM4-M2 aluminum alloy case
  • 1 x X515 storage expansion board
  • 1 x C235 aluminum alloy heatsink
  • 1 x 0.96 inch OLED display
  • 1 x Scews pack accessories

Additional accessories to purchase yourself:

  • Raspberry Pi Compute Module 4 CM4
  • A minimum 16 Gb class 10 memory card is recommended.(In fact, you don't need Micro SD card if you use CM4 with eMMC, because you can flash the firmware into the eMMC.)

User Manual

Installation Video

For NASPi CM4-2.5 and NASPi CM4-M2: https://youtu.be/lXBK5-GFQ48

Please follow the steps below

Flash OS Image

Due to CM4 has a version with eMMC, micro SD card is optional. If you are using the CM4 with eMMC, you don't need to buy a extra Micro SD card.

You flash the OS image into different media according to your own situation.

1. Flash OS into the micro SD card

A minimum 16 Gb class 10 memory card is recommended.
Please refer to Official installation tutorial

2. Flash OS into the eMMC of CM4(Optional)

You can falsh OS into the eMMC if you use the CM4 with eMMC, refer to the following step.
1. Short OTG Pin, refer to the picture below.
 
2. Connect a computer that will be used to load the eMMC to the USB C port on the CM4-M2 board. The computer will provide both power and data to the CM4. (Type-A to Type-C OTG cable need to be purchased seperately)
3. Then rerfer to this tutorial to flash raspberry pi OS
4. Remove the jumper of OTG after flashing is complete, then restart your device;
PS:If you use CM4 with eMMC, then SD card cannot be used.

3. Preconfigure Device for CM4

Now we think you have successfully flashed the OS to the storage media (mciro sd card or eMMC of CM4). If you attempt to boot now you will not have working USB ports, ssh, or any wireless configuration, so do not remove your SD card, proceed as follows.

We can preconfigure your CM4 device by plugging mico sd via sd reader into a windows computer / Pi. You should see the “boot” volume where we can preconfigure our CM4 to be working right from the start.

3.1 Enable USB Ports

When mounted in the IO board the USB ports will not function without making a change to config.txt and adding an overlay.
Add the following line to config.txt:
dtoverlay=dwc2,dr_mode=host
After adding this line the two USB ports (as well as the “External USB” header) will function the next time the CM4 boots.

3.2 Enable SSH

It's very useful to have SSH enabled when working with the Compute Module 4. It is enabled simply by creating an empty file named:
touch ssh
in the root folder of the “boot” volume (the top-most folder of the drive where start4x.elf, fixup.dat and those files are located)
Now when the Pi starts up SSH will automatically be enabled!
PS: This step is optional, you can also enable ssh through the raspi-config program after the device boot

3.3 Preconfigure WiFi / Wireless (Optional)

You can also preconfigure the Compute Module 4 (and any Pi) by creating wpa-supplicant.conf at the base of the “boot” volume like we did with “ssh” file. In fact, you can setup your wifi after you boot up.
Create a new file named wpa-supplicant.conf that contains the following:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
country=US
update_config=1

network={
 ssid="YourNetwork"
 psk="YourPassword"
}

When this file is created in the base of the “boot” volume it will automatically be applied to the Pi upon the next startup. Make sure to adjust your country=US line to your own country as this can impact what channels and functionality are available from your WiFi card!

Then you can insert your micro sd card into the device & power on it.

4. Installing script

After the device is reboot, install the following script to get safe and software shutdown function: refer to XScript

5. Enable OLED display

Refer to How to enable OLED display

6. Flash OS into the NVME SSD(Optional)

Load OS into ssd and you can get extremely fast running speed, you need to refer to the above steps to flash the OS into the Micro SD card firstly, then insrt the Micro sd card, turn on the device, and then click Applications =>Accessories =>SD Card Copier, run the SD Card Copier program, and copy the OS to the ssd as shown in the figure below.

 

Click Start to run. Then shut down, unplug the SD card, and restart the device.

FAQ

Q: How to enable the POE option?

A. The POE header on X515/X510 is reserved to be compatible with the official POE+ HAT. But we don't know if the case will be compatible with the installation of official POE+ HAT.

Hi, I am using both slots with 1Tb SSDs. The NVME SSD is working but the system does not see the SATA SSD. Is there a special process to set this up? Are there cli commands to debug this?

Here are a few dumps.

It is all working now. I had inserted the SSD upside-down.

What purpose does the AA pin-pair on the front right of the board, immediately above the OTG pin-pair, serve?

The 2 pins right above the OTG are AON (auto power-on), you can use the jumper cap to realize his function.

Is there any documentation available for the GPIOs used by this board. Specifically, I would like to know the functions of the GPIOs related to power management. As far as I can tell, it's something along these lines:

GPIO17 [OUT, active high] - Set to indicated OS boot complete? GPIO27 [OUT, active high] - Request power off. GPIO4 [IN, active high] - Shutdown requested.

It seems like GPIO17 needs to be set for GPIO4 to have any function. GPIO27 seems to have different behaviour depending on whether the power button has been pushed.

Could someone clarify exactly how the power management GPIO interface is supposed to work? There are clearly power LED blink sequences involved as well that aren't document anywhere. A datasheet for the power management IC would be greatly appreciated.

I would like to know what the 6 pin header next to the front usb port does.

I was guesing/hoping it was for i2c spi and/or uart but i couldnt find anything about it. If this is the case i would also like to know what the pinout of this header is.
