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.

Unplug the system completely – remove power and all peripherals
Straighten a paperclip
Locate the unlabeled CMOS reset hole next to the HDD LED
Using the paperclip, depress the button inside for 30 seconds.

Reconnect the system and turn it back on.
Do not touch the system for 2 minutes. It may reboot several times while it reconfigures the CMOS.
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.

Enabling Auto Power On

The K800 can be configured to turn on automatically when DC power is connected. This is useful for power outage recovery or if the unit is mounted in a hard to reach location. You can enable Auto Power On by following the steps listed below.

Note: In future revisions the name of this setting will be changed. “Auto power ON’ under the Power tab will be the new name and location.

Power on the system and press Del a few times to access the “Front Page” menu
Choose “Setup Utility”
Navigate to Advanced > PCH-IO Configuration

Locate “State After G3”
Change it to”s0 State” to enable auto power on.

Automotive Timings

Feature Overview

The ignition sense feature can be used to turn the Karbon unit on and off with a 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. Below we have outlined the steps to open this virtual COM connection and possible settings for ignition sensing on the K800.

Download the Putty tool from putty.org (link at the top of this document)
Look in Device Manager and find the highest numbered USB serial device, COM5 in this example
Open Putty. Set the connection type to Serial and change COM1 to COM5.
Click “Open”. This will open a virtual connection to the MCU (no physical cable is required)

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.

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

Embedded MCU (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

    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.

Firmware Updates

In order to support over-the-air firmware updates, the K800 has a two stage bootloader; a ROM bootloader, that can be started with physical access to the system, and a USB bootloader that supports updates from the OS.

Entering the ROM Bootloader (manual):

Detach the K800 system from wall power
Use a paper clip to depress the settings switch located above the front USB 3.0 ports
With the switch held down, re-attach system power
The MCU should now boot into the NXP ROM bootloader

Entering the USB Bootloader (manual):

Boot the K800 to the operating system
Use a paper clip to depress the settings switch located above the front USB 3.0 ports
With the switch held down, send the ‘reset’ command to the MCU’s UART port
The MCU should now boot into the second stage USB bootloader

Accessing the MCU

The MCU (microcontroller) can be accessed via a serial interface. In the example below, we will use Putty to access it.

Download the Putty tool from putty.org
Look in Device Manager and find the highest numbered USB serial device, COM5 in this example
Open Putty. Set the connection type to Serial and change COM1 to COM[X] (enter the number identified in the previous step)
Click “Open”

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.

DIO & LEDs

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.

Examples:

# 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
BAUD=8

# Name of slcan device to attach
DEV=can0


# Detect correct port for device interfaces
TERM_PORT=$(ls -l /dev/serial/by-id/ | grep 3f35_a101 | sed 's/.*\///g' | awk '{if(NR==2) print $0}')
CANB_PORT=$(ls -l /dev/serial/by-id/ | grep 3f35_a101 | sed 's/.*\///g' | awk '{if(NR==1) print $0}')

# Start or stop the service
while getopts ":ks" opt; do
    case $opt in
        k)
            # Stop the SLCAN service and turn off the can device
            echo "Shutting down can interface..."
            sudo ifconfig $DEV down 2> /dev/null
            sudo pkill slcand

            sudo slcand -c /dev/"$CANB_PORT"
            sudo pkill slcand
            ;;
        s)
            # Open the can device, and start the slcan service.
            echo "Terminal interface on: $TERM_PORT"
            echo "CAN Bus  interface on: $CANB_PORT"

            # Set the mode to slcan
            echo -ne "set can-mode slcan" > /dev/$TERM_PORT

            echo "Attaching slcan device..."

            # Attach to the port with slcand
            sudo slcand -s$BAUD -o /dev/"$CANB_PORT" $DEV

            # Give interface time to come up
            sleep .25

            # Enable the inteface
            sudo ifconfig $DEV up
            sudo ifconfig $DEV txqueuelen 1000

            echo "Interface is set up."
            ;;
        \?)
            echo "Invalid option: -$OPTARG" >&2
            exit 1
            ;;
        :)
            echo "Option -$OPTARG requires an argument." >&2
            exit 1
            ;;
    esac
done
