What Operating Systems are supported?

Windows 10 IoT 2021 and Windows 11 are supported. In most applications it is NOT necessary to disable the e-cores.

The K800 also supports Ubuntu 22.04 for Intel IoT with Kernel version 5.17 or newer. Older Ubuntu and Kernel versions are not supported on the K800 series.

What chipset do the Ethernet ports uses?

The onboard LAN ports use the I225. The optional 10gig Modbay expansion card uses the X550.

What Baudrate is supported on the K800 COM ports?

The K800 series supports up to 115200 baudrate on the COM ports. Higher baud rates can be achieved by implementing the CAN port. See how to do this through the Embedded Microcontroller MCU.

How do I disable TurboBoost on the CPU?

TurboBoost can be disabled in the BIOS of the system. Navigate to Advanced and set Expert Mode to Enabled. Then, go to:
Power & Performance -> CPU – Power Management Control -> Boot Performance -> Set to Max Non-Turbo Performance

How do I enable the external SIM slot?

The K800 series can be configured with an internal modem, the AMIT series modems. If configured with a SIM card, this would be installed internally, directly on the modem. However the modem can be configured to use the external SIM slots to allow easier switching by users. It is recommended to configure the following BIOS setting to enable both external SIM slots:

Setup Utility -> Advanced page -> PCH-IO -> OnLogic Feature Configuration -> SIM Card Muxing -> Set to “Mode 4“
Make sure to Save & Reset via the F10 function key or through the Exit page.

How do I use the integrated video ports, instead of the GPU?

The K800 series can be configured with a GPU. For some customers this is used to drive multiple high-resolution displays, and the video output will automatically output through the GPU. However in some cases you may want to use the GPU for specific computational applications, and use the integrated DisplayPorts. To enable this option, you will want to change the “Primary Display” output in the BIOS. Navigate to:

Setup Utility -> Advanced page -> Set “Expert Mode” to Enabled
Then go to:
Setup Utility -> Advanced -> System Agent (SA) Configuration -> Graphics Configuration -> Primary Display -> Change to “IGFX”
Make sure to Save & Reset via the F10 function key or through the Exit page.

Troubleshooting

Clearing the CMOS

If the K800 fails to power on or is otherwise unresponsive, a CMOS reset may help. Follow the procedure outlined below to clear the CMOS.

1. Unplug the system completely – remove power and all peripherals
2. Use a long, thin tool, such as a straighten a paperclip
3. Locate the unlabeled CMOS reset hole next to the HDD LED
4. Using the tool/paperclip, depress the button inside for 30 seconds.

5. Reconnect the system and turn it back on.
6. Do not touch the system for 2 minutes. It may reboot several times while it reconfigures the CMOS.
7. If successful, the unit should boot back up and run normally. It is now ready to use again. If the unit is still not responsive, reboot it one more time and then contact OnLogic Tech Support.

Once you’ve accessed the BIOS, you can find the Fast Boot setting under the Boot tab.

10Gb Ethernet Modbay disappears from OS

K800 series systems outfitted with the 10Gb Modbay (MODBAY-10GLAN01) may experience issues while in use, causing the ports to crash and become unusable. To fix this issue, download this file and follow the Update Instructions.
Note that the system must be booted into a Windows environment for this Update. A temporary Windows installation can be used on the system, or the unit(s) can be returned to OnLogic. Contact OnLogic Tech Support for RMA details.

Orders shipped after 11/20/2023 already have this update applied

10Gb Ethernet Modbay limited speed

If you have a 10 Gb Modbay installed in your system, and it is not operating at full speed, you may need to update the ethernet controller firmware. It should be at least version 3.6 or higher.

There are different update steps depending on if you’re running Windows or Linux. Download the relevant steps and follow the steps in the downloaded file:

Windows

Linux

CAN bus connection instability

If you experience issues with using or accessing the CAN bus on your K800 system, this can be resolved by updating to the latest microcontroller firmware. Download the firmware at the top of this page, and follow this guide:

Updating Microcontroller Firmware with ZMU

Accessing the Microcontroller (MCU)

The embedded microcontroller unit (MCU) is used to interface and control various aspects of the system such as CAN, DIO, and ignition sensing. To communicate with the MCU, follow the steps below for your installed OS.

Windows

1. Download the PuTTy tool from putty.org
2. Look in Device Manager and find the highest numbered USB serial device, COM5 in this example
3. Open Putty. Set the connection type to Serial and change COM1 to the COM # you found in the previous step. This example uses COM5.
4. Click “Open”. This will open a virtual connection to the MCU (no physical cable is required)

5. To confirm you have the correct port open, type “help” and press enter. The help text should appear. If it does not, try a different COM port.

---

Linux

1. Use a program such as PuTTy to interface with the microcontroller (MCU). You can run the following command to install it (you will need an active internet connection for this):
   sudo install putty
2. The MCU will typically enumerate as ttyACM0. It enumerates as a serial-interfaceable USB device. If you run into issues accessing ttyACM0, you can run the following command to identify the other port(s):
   sudo dmesg | grep tty

3. In this example, the MCU is on ttyACM0. Open PuTTy, enter the port #, and set the connection type as “Serial”. The other settings can be left on their defaults (i.e. baudrate = 9600).

4. To confirm you have the correct port open, type “help” and press enter. The help text should appear. If it does not, try a different port #.

Automotive Timings

Feature Overview

The ignition sense feature can be used to turn the Karbon unit on and off with a battery, or vehicle’s ignition. It can also be used in non-automotive applications using a switch instead.

An example configuration is shown below. The switch connects positive DC power to the IGN pin. The unit will turn on when power is applied to the IGN pin, and turn off when power is removed. These events have configurable delays.

Enabling and controlling ignition sense

Ignition sensing can be enabled and adjusted through a virtual COM connection to the system’s microcontroller (MCU). You can open this communication to the MCU using a program such as PuTTy. Refer to the steps above, Accessing the Microcontroller (MCU), for help accessing the MCU.

Example ignition settings

The following shows an example configuration for automotive timings. Enter each command one by one.

For further help text, type lpmcu config

Command	Effect
lpmcu config automotive-mode true	Enables automotive mode
Command: lpmcu config startup-timer [X] Example: lpmcu config startup-timer 10	Effect: turn on X seconds after IGN pin receives power Example: turn on 10 seconds after IGN pin receives power
Command: lpmcu config hard-off-timer [X] Example: lpmcu config hard-off-timer 60	Effect: force shutdown system after X seconds (failsafe to protect battery) Example: force shutdown system after 60 seconds (failsafe to protect battery)
Command: lpmcu config soft-off-timer [X] Example: lpmcu config soft-off-timer 20	Effect: shutdown X seconds after IGN pin loses power Example: shutdown 20 seconds after IGN pin loses power

CAN & DIO

The Karbon 800 has an embedded NXP i.MX RT1050-series microcontroller that can communicate with the host processor over USB. Its features include:

• Configuring the system LEDs
• Reading/writing the system DIO
• Using system Digital Outputs in PWM mode
• Configuring system automotive settings
• Managing the system CAN interface

To provide access to these features, the MCU supports a composite USB-CDC VCOM connection (VID: 0x353F, PID: 0xA101):

• Interface 0: A UART terminal supporting commands for a range of features
• Interface 2: A dedicate USB serial CAN interface

C:\Users>python -m serial.tools.list_ports -v

COM15
    desc: USB Serial Device (COM15)
    hwid: USB VID:PID=353F:A101 SER=500100D20F3861D2 LOCATION=1-11:x.2 <--- CAN Port

    hwid: USB VID:PID=353F:A101 SER=500100D20F3861D2 LOCATION=1-11:x.0 <--- UART Port

The MCU shell is a fully-featured virtual UART shell exposed over the MCU’s first USB CDC-ACM interface. This shell supports both command history and line editing, and can optionally serve as an output target for driver log messages. For a complete command reference see, the shell command reference.

DIO/CAN/Power Switch header

The Karbon 800 series 20-Pin header provides the following interfaces: 8-bit (4-in, 4-out) Digital Input Output (DIO) or General Purpose Input Output (GPIO) with optically isolated terminals, one CAN bus connection, and an optional external power switch connection.

The DIO is optically isolated, meaning that the terminal is separated from other motherboard features for protection. The DIO terminal requires external power from a 5~48V DC source through Pin 20 with GND to Pin 19 in order to function.

The Isolated Power Supply (ISO PSU) can be a voltage source from 5~48V to interface with external digital IO. The maximum power draw from the supply should not exceed 0.6A under normal operating conditions. Individual DOut pins will be damaged by loads in excess of 150mA. The ISO PSU must be a DC Limited Power Source (LPS) power supply.

Mating power switch cables should be a twisted-pair wire with floating shield to assure proper
immunity to EMI/RFI. It is recommended to keep wires at less than 3 meters in length. Any remote power switch connected between pins 1 and 2 should be momentary contact type only.

Connection Diagrams

DIO & LEDs

Examples:

All digital inputs/outputs support reading the current logical state of the pin. Digital outputs additionally support setting the output state of the pin, and digital inputs support reporting the transition count of the pin (both edges). The K800 also support configuring digital outputs as PWMs, and configuring the PWM output’s pulse and duty cycle. For a additional command reference see, the shell command reference. The DIO can also be changed to Byte Mode as documented below.

# Turn on LED 0 output
uart:~$ dio set LED0 0 true
# Check the state of Digital Input 0
uart:~$: dio get DIO0 input 0

CAN

The Karbon 800 has an on-board CAN 2.0 A/B interface. The CAN interface supports configurable baudrates from 100k – 1M, and two message parsing modes:

# Change the parser mode to 'slcan'
uart:~$ set can-mode VCAN0 slcan
# Set the can-baudrate to 1M
uart:~$ set can-baudrate VCAN0 1000

When in slcan parsing mode, the K800 CAN interface can be used with linux ‘slcand’ utilities, which support socket can over serial. To get up and running with slcan, start by installing can-utils:

$ sudo apt install can-utils

Then, detect and setup the Karbon can interface. For example:

#! /bin/bash

# ASCII Command vs CAN Bitrate
# s0 --- s1 --- s2 --- s3 --- s4 --- s5 --- s6 --- s7 --- s8
# 10     20     50     100    125    250    500    800    1000  Kbits/s
