Software Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-7bha9) Where can I download the latest Axzez Interceptor Operating System (OS) image? A. The custom Interceptor OS is available for download at: https://www.axzez.com/interceptor-os.img.gz (https://www.axzez.com/interceptor-os.img.gz) See the Axzez Software Downloads (https://www.axzez.com/software-downloads)page for more information. Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-9bfg4) How do I install the Axzez provided OS? A. After downloading the interceptor-os.img.gz file, the easiest way is to just use something like the Raspberry Pi Imager (https://www.raspberrypi.com/software/)tool or Etcher (https://etcher.download/)to copy our image to a USB flash drive and boot your Interceptor Carrier Board with that USB flash drive inserted into any USB port. You can also use the following Linux commands to write our image to a USB flash drive (where /dev/sdb is your USB flash drive): zcat interceptor-os.img.gz | sudo dd of=/dev/sdb bs=1M sudo eject /dev/sdb Insert the USB flash drive into any USB port on the Interceptor board, turn the power on, and follow the simple installation instructions. Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-7pbl2)Is there a minimum CM4 bootloader version required by the Axzez Interceptor Carrier Board? A. The only requirement is that you have the ability to boot via USB. This capability was released with the RPi4 bootloader eeprom version 2020-12-14. To install this (or newer) bootloader, please follow the instructions here (https://www.raspberrypi.com/documentation/computers/compute-module.html#setting-up-the-cmio-board)to setup and build "rpiboot". Then follow the instructions here (https://www.raspberrypi.com/documentation/computers/compute-module.html#compute-module-4-bootloader)to flash the latest or desired eeprom version. We recommend the "BOOT_ORDER=0xf215" for setting up our provided operating system. Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-b1u57)Is there a base boot.conf that I should be using? A. As noted before, we do recommend a BOOT_ORDER of "0xf215", but we also recommend the following if you want to take advantage of our power off/on functionality (our installer sets these automatically): POWER_OFF_ON_HALT=1 WAKE_ON_GPIO=0 BOOT_ORDER=0xf215 Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-2dm96)Are there any drivers that I need to install to use the Axzez Interceptor Carrier Board? A.

Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-7mufv)With a 4K monitor, everything is small and difficult to see/read. Can I change the resolution/DPI (scale) of the Wayfire Compositor (desktop)? A. Yes you can change the resolution, or increase the DPI in .config/wayfire.ini. For example: [output:HDMI-A-2] scale = 1.5 For more information, please see https://github.com/WayfireWM/wayfire/wiki/Configuration#output (https://github.com/WayfireWM/wayfire/wiki/Configuration#output) Interceptor Carrier Board Hardware Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-adruf)I have the "Lite" CM4 board (no eMMC), and I do not see an SD Card slot on the Interceptor Carrier Board. Can I still use the Axzez provided Operating System (OS)? A. Yes, you can. Our OS can be booted into "Live" mode, installed to the USB flash drive, or installed to an HDD/SSD if you have that connected. Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-26j64)My ATX power supply fan started to spin when I turned on the Interceptor Carrier Board but then stopped a few seconds later and my USB keyboard and mouse do not work. What is happening? A. Through extensive testing we have found several power supply units that do not have a reliable and stable +3.3V rail. If that power supply also has Under Voltage Protection (UVP), it can shut down the power supply [except for the +5VSB (+5V standby)]. This will still power up the CM4, but not USB, RJ-45, RS-45 or SATA. You can use a Digital Multimeter (DMM) to verify that a +3.3V pin in the ATX connector has dropped below the minimum value for your power supply unit (typically 4-5%). We have observed a power supply failing with only 0.2A on the +3.3V rail, even though it was rated for 24A on that rail. Seasonic PSUs have been consistently reliable in our testing, but you can find a list of all tested power supplies here: PSUs with a Reliable +3.3V Rail (Verified by Axzez) Antec Earthwatts Gold Pro Series Corsair RMx Series EVGA SuperNOVA G3 Series FSP Group Inc power supplies Mini-Box picoPSU-160-XT RGEEK 24pin DC ATX 12V DC (Pico PSU) Seasonic S12III Series Seasonic Focus GX Series SilverStone Technology SST-FX (Flex ATX) Series Streacom Nano90 PSUs with an Unreliable +3.3V Rail ARESGAME AGV Series Coolmax I-500 Corsair CV Series EVGA W1 Series Zalman GigaMax GVIIA Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-126kf)Which are the WAN and LAN ports on the Interceptor Carrier Board? A. The ports are marked A-B in the diagram to the right, in the shape of an "N" starting on the lower left-hand corner of the RJ-45 and ending in the upper right-hand corner. Port 'A' is the WAN port and gets its IP address from the network. Ports 'B-D' are the LAN ports, and the Axzez provided Operating System sets the IP address for each LAN port via the included DHCP Server software. These ports can be reconfigured by modifying the following file: /usr/libexec/config-rtl8367rb.sh Wireless can be configured with the following commands: wpa_passphrase <ssid> <passphrase> | sudo tee /etc/wpa_supplicant/wpa_supplicant-wlan0.conf sudo systemctl enable wpa_supplicant@wlan0 Q. (https://www.axzez.com/forum/interceptor-carrier-board/frequently-asked-questions#viewer-7cnaj)What is the pin-header layout? A. The 8-pin header (J2) pins, starting with the bottom right pin: 1 (+) & 2 (-) are for the power LED, 3 & 4 are for "power on" button, 5 (tx) & 6 (rx) are for UART serial cable, and 7 & 8 are ground.
