The CM4 module has a hardcoded boot order of eMMC > SATA M.2 > USB. This can be problematic if the image on the eMMC or SATA M.2 becomes corrupted or needs to be erased for other reasons. The simple solution is to erase the boot partition. This can be done one of two ways.
Note that this method can only by used to wipe eMMC storage, not a SATA M.2

The storage has now been erased.
Proceed to one of the operating system installation guides on this page.
If the Linux image on the Factor unit is still bootable, you can use the terminal to erase the boot partition.
Run the lsblk command to list the storage devices
In this example, the boot partition is stored on /dev/mmcblk0p1
The following command will copy zeroes over that partition, effectively wiping it and preventing the Pi from booting to it.
sudo dd if=/dev/zero of=/dev/mmcblk0 status=progress
A SATA M.2 storage drive will likely show up as sdb, so this command will wipe the M.2’s boot partition:
sudo dd if=/dev/zero of=/dev/sdb status=progress
Once the drive wipe has completed, proceed to one of the operating system installation guides on this page.
The FR200 series serial mode can be controlled by configuring the embedded FTDI EEPROM. You will need to install the utility before updating the serial mode.
Install required libraries: sudo apt install libconfuse-dev libusb-1.0-0-dev
and build tools: sudo apt install cmake build-essential
Download the latest libFTDI Source .tar.bz2 from the Intra2Net page here:
|
Example:
wget https://www.intra2net.com/en/developer/libftdi/download/libftdi1-1.5.tar.bz2
Download the configuration file for your required mode:
– wget static.onlogic.com/resources/firmware/documentation/configs/FR200_RS232.conf
– wget static.onlogic.com/resources/firmware/documentation/configs/FR200_RS422.conf
With the serial port configuration enabled, the port will now enumerate as /dev/ttyUSB[x], where [x] is the port number. This is typically /dev/ttyUSB0, but may be enumerated differently depending on other USB devices connected. You can also identify the serial port chip via the hardware ID, which is F81439A.
The TPM is an optional Nuvoton-based hardware add-on for the FR200 series systems.

Important notes about Factor PoE (Power Over Ethernet) PD setup and the various revisions of the module.
Do not connect both power inputs at the same time. Only connect x1 power connection (either PoE OR terminal block).
Review specific details in the specific models below\
The ADP125 is an isolated PoE PD (powered device) modules. Factor series systems configured and shipped in August 2024 or later have this version of the module. This offers isolation/protection from transient voltage of up to 100KV.
Factor Series systems configured with PoE PD modules and shipped before August 2024 will use the ADP122. Important notes about Factor PoE (Power Over Ethernet) setup when using the ADP122 addon module:
Do not connect both power inputs at the same time. Only connect x1 power connection (either PoE OR terminal block).\
The ADP122 is a non-isolated PoE PD (powered device) module. The FR200 product family provides a ground scheme that isolates digital and chassis ground. Downstream equipment may modify this ground scheme by shorting chassis and digital ground together within the cabling or attached circuitry. Downstream or upstream devices that depend on isolated digital and shield/chassis grounds may experience performance degradation as a result of this equipment.
In the event of a break in ground scheme due to installation environment and connected equipment, there is no safety concern. However, equipment that depends on ground isolation for protection or measurement may experience loss of performance including, but not limited to, inaccuracy of power measurement or power delivery or equipment damage.
You can review additional details in the Errata document below:
If you are having issues accessing the RTC, especially after installing a new operating system, you will need to add these lines to your config.txt file:
You can also refer to the Raspberry PI CM4 documentation for more info. Section 2.13 under "Real time clock (RTC)" at this link:
Functions listed in this FR202 Features section are in addition to the Factor Series Features section above, and for the FR202 system only. The below features and not available on the FR201 platform.
Note: For the best experience, always update to the latest firmware version before testing these commands.
The FR202 Digital IO is connected to the CM4 via a virtual USB-CDC-ACM serial port; you can see that the USB device is detected using lsusb and OnLogic’s USB Vendor ID:
lsusb -d 353f:
Data can be sent to the device over its virtual serial port, which will be available in /dev :
ls /dev | grep ACM
The serial port can operate either as an interactive UART terminal, or as an endpoint for raw byte commands.
The FR202’s UART shell supports line editing, history, and TAB completion. Digital inputs and outputs are collected into groups, and dio commands are performed on those groups.
For instance, DO_G0 is “Digital Output Group 0”. A complete list of devices can be produced by running device list. Once you have selected a device, dio commands may be run:
To exit the interactive terminal and enter byte-processing mode, run the byte_mode command.
For information about other terminal commands, see:
When using byte mode, DIO commands are sent in the form of command packets, and each command will receive a status (and optional data) as a response.
The command header is eight bytes in length:
All command headers must indicate the type of data to follow, by setting the command kind:
Each command sent will recieve a response from the microcontroller. This response may contain data, but can always be examined to determine if the command succeeded.
The DIO command format is as follows:
The digital IO command supports the following actions:
A sample application demonstrating some simple features of the display is provided for each of the supported Operating systems here:
On systems pre-installed with an OS from OnLogic, the display demo files are located under /usr/sbin/demo-display and /etc/systemd/system/demo-display.service
Pieces of this sample package are referenced in the display sections following. It also ships on all OnLogic-provided Pi OS and Ubuntu software images, enabled by default. To disable it, run sudo systemctl disable demo-display from a terminal window.
If you have deployed Bookworm onto your Factor unit since receiving it you may see the demo program not work right away. If you see this behavior please type `raspi-config` in the Linux terminal, select `Interface Options` then select `I2C` and enable it.
Display Controller:
Controlling the Backlight
Touch Controller:
Display backlight is controlled by an i2c expander at 0x3C on I2C1.
The OnLogic-provided utility “fr202-i2c” can control the backlight with the commands:
Enable: fr202-i2c set p7v6_shdn 0
Disable: fr202-i2c set p7v6_shdn 1
A list of other controllable signals is available in the help text for the tool. It is provided with the display code samples as well as
The backlight can also be enabled using the i2ctools utilities as follows:
Configure GPIO IC: i2cset -y 1 0x3c 0x03 0x81
Enable: i2cset -y 1 0x3c 0x01 0xbf
Disable: i2cset -y 1 0x3c 0x01 0xff
pip install st7789
apt install python3-rpi.gpio python3-spidev python3-pil python3-numpy
The provided python example “demo-display” demonstrates the use of Python’s PIL and the ST7789 display library to display static images and text. It runs as a service in OnLogic-provided Pi OS and Ubuntu installations as well.
pip install opencv-python
apt install libatlas-base-dev
pip install -U numpy
The separately provided “st7789-video” demonstrates the use of opencv’s video library to show a video on-screen. By default, the sample is configured to read and display a video called “test.avi” in the same folder as the application. A video is not provided.
The ADC is attached to SPI 4 CS0. Look for this device name in your OS hardware list. Example:
/dev/spidev4.0
The ADC part number is LTC2448; a description of the SPI protocol can be found in the device manual .
An example of accessing the ADC can be found in the FR202-demo program as well. You can download it from . Search for “adc” in the demo-display file for examples.
All ADC channels are differential and configured as follows: ANALOG IN 0: Channel 0+1
ANALOG IN 1: Channel 2+3
ANALOG IN 2: Channel 4+5
ANALOG IN 3: Channel 6+7
TEMPERATURE 0: SENSOR Channel 8+9, REFERENCE Channel 10+11
TEMPERATURE 0: SENSOR Channel 12+13, REFERENCE Channel 14+15
***This has been resolved with a new image deployment as of Mid-August 2025 but systems from January-August 2025 may still experience this issue and will require the workaround below or a reimage***
Starting in the beginning of 2025, our Raspberry Pi OS image files had an automatic service included to help manage the FR202 display. Services are programs that automatically launch and run in the background in Linux operating systems. This service is included in both the FR201 and FR202 as they utilize the same motherboard/processing units, and therefore have the same image files. We had found that this specific service can lead to error messages on the FR201 as it is searching for hardware that is not present in the system. This can lead to larger than necessary log files, which can consume storage space unnecessarily.
On the FR202 this service makes the LCD screen show the screen-test outputs, and the demo-display files can be modified to match the specific use case. This service identifies the FR202 hardware and runs properly, but on FR201s it fails since that hardware is not present. When it fails, this results in repeated lines of errors captured in the OS error logs. Essentially, it can consume storage space, and may cause concerns for those who are unaware.
The OS images this affects are our Raspberry Pi OS images (full/lite, and 32/64 bit). The original revision images were used through the end of December 2024, with the new revision that includes this service starting to be used at the beginning of January 2025. Ubuntu does not have the service included.
Because of our OS file management, FR201s and FR202s use the same image files. This means that the demo-display and service setup always happen, regardless of the system model. We recommend disabling the service in the following cases:
User has an FR201
User has an FR202 and doesn't have/want to use the LCD
For those that want to see if the service is running, they can run the following command:
systemctl list-units --type=service --state=running
If the service is running, and it needs to be disabled, the following two commands should be run:
sudo systemctl stop demo-display.service sudo systemctl disable demo-display.service
To check if the demo-display file is installed, it is located under the /usr/sbin directory.
If you are encountering general issues with your FR200 series system, such as the Real-Time-Clock (RTC) disconnecting, various ports not being detected, or features not working as expected, make sure you’re using the OnLogic provided config.txt and usercfg.txt files. These add additional functionality to the system, and allow the Raspberry Pi CM4 module to properly interface with the OnLogic designed FR200 series daughterboards. You can download the files from the section above.
You should make sure that any Factor (FR201 and FR202) units have the following lines in the config.txt file:
For the FR202 specifically, you will also need to ensure the config.txt file includes:
CPU Panic error messages may be see during/after an OS installation due to using an older or malfunctioning USB drive. Please make sure to use a USB 3.0 drive or newer, installed into the USB 3.0 slot on the Factor system. A different USB drive may also need to be used.
If one of the Ethernet ports is not detected or shows as Disabled in Ubuntu, you can follow these steps to add it into Netplan and enable it.
Run the following command:
Look for the Logical name, which is required in the next step, and run the following commands
Add the logical name (found in Step 2) to the 50-cloud-init.yaml file. See an example below:
Close and save, then run the following commands
If the TPM modules is not working properly, refer to the section above for installing and configuring the necessary files.
Booting Ubuntu via USB may result in a black screen if the eMMC has an OS image on it. Wiping the eMMC and/or M.2 drive is recommended if that is encountered.
Some operating system versions require different config.txt settings to make the power indicator light function. If your Factor unit is otherwise functional, but the power indicator light is not lighting up, this is likely an issue with the config.txt file. Look for the following lines in the file:
Replace those lines with
If you’re seeing issues using the FR202 LCD display, or seeing errors when running the FR202-demo scripts, make the following changes to your config.txt file:
Delete/comment out:
dtparam=spi=on
Add:
dtoverlay=spi4-1cs dtoverlay=spi3-1cs,cs0_pin=24 dtoverlay=i2c5,pins12_13=on,baudrate=40000
After making any changes, save and restart the operating system.
The Factor’s CM4 compute module has a built-in Wi-Fi antenna that it uses by default instead of the attached external antenna. The config file /boot/firmware/config.txt (or /boot/config.txt depending on your OS) may need to be updated for the CM4 to use the external antenna to connect to Wi-Fi instead of its internal one. To do this, open the specified config file and add the line ‘dtparam=ant2’, save, and then reboot your system. This should provide a noticeable improvement in Wi-Fi speeds.
In a Factor with 4G LTE and Wi-Fi, there can be an issue where the devices “compete” for priority over each other, preventing them from connecting properly to the internet. To resolve this, you will need to set the priorities for the devices in the ‘/etc/dhcpcd.conf’ file for the Raspberry Pi OS and in the netplan configuration for the Ubuntu OS. You can do this by entering the following into the configuration file:
interface wlan0 metric 100 interface eth0 metric 200
The lower the metric, the higher priority. So in this example, the WIFI device (wlan0) will take priority over the ethernet. What that is doing is ensuring that the WIFI device’s default route is being used to route network traffic. The customer may need to set priorities for each network device, which for Factor is eth0, eth1, wlan0, and usb0, where usb0 is the AMIT card.
The Out-of-Box version of the following operating systems on the FR200 systems can encounter issues with the NWK300 modem where you may not be able to set up the modem properly:
Raspberry Pi (Bullseye)
Raspberry Pi Lite (Bullseye)
Ubuntu Desktop/Server 20.04 - 32 Bit
Ubuntu Desktop/Server 22.04
The issue can be resolved by running an OS update. Run the command:
'sudo apt update && sudo apt upgrade'
And the system should be able to use the modem normally. This issue is not present in the Bookworm or Ubuntu 24.04 operating systems.
The system is now ready for use.
The system is now ready for use.
Note: the screws will not line up if the module is rotate 180 degrees.
