A splash-resistant, co pact enclosure includes rugged ounting features and sealed connectors.
SMA connectors are used for both cell phone and GPS.
Connectors
External Connectors A (Grey) and B (Black)
The external connectors are used for attaching CT650 to external power and signals in a vehicle.
The connectors are auto otive-style, providing sealing and vibration resistance for each wire.
Mating Connector Components
The external connectors are Deutsch DTM series and can be found at https://laddinc.co and
other distributors.
Connector A, Grey: Deutsch DTM06-12SA

Console Port
Progra ing and developer interaction with the Linux operating syste is done through the
console port. The console port is located on header by the ain connector.
Pin 1 is indicated by a s all white triangle.
Signals levels are 3.3 volt UART TTL. A signal conver ter is needed in order to connect the
console port to a PC.
Dyacon has used FTDI TTL-232R-3V3 USB to UART converter with a odified connector.
These are available fro electronic co ponent distributors, such as Mouser and Digikey. The
converter is supplied with a six-pin
receptacle. This ust be odified to the
following.
Pin Number Pr cess r Pin
1 TX (Output)
2 RX (Input)
3 GND
Contact Dyacon if you would like us to
supply you with a odified converter.

Kernel ersion
Linux 4.14.73
U-boot 2018.07
De elopment Tools
The develop ent tools have been build using Ubuntu 18.04.
The develop ent toolchain can be obtained at
https://drive.google.co /open?id=1K9EeAicM1Nnls0qH-MTj ZF0cGxpjkSt
Extract the toolchain to your desired location. After doing so, run the relocate-sdk.sh script to
update the paths to the new location.
The si plest way to use the toolchain is to add the {extraction directory}/bin/ to your PATH
environ ent variable and then to use ar -linux-gcc, ar -linux-ld, etc.
Exa ple:
mkdir ~/CT650-toolchain
tar -xvf CT650-toolchain.tar.xz -C ~/CT650-toolchain/
cd ~/CT650-toolchain
./relocate-sdk.sh
cd ~/testapp/

File System
The syste contains the following partitions:
cblk0p2 – boot partition A
cblk0p3 – boot partition B
cblk0p5 – key storage – Mounted at /key
cblk0p6 – rootfs partition A – Mounted at /
cblk0p7 – rootfs partition B

cblk0p9 – app partition B – Overlayed at /app, /etc, and /lib in rootfs partition B
cblk0p10 – data – Mounted at /data
When received the syste is configured to use boot partition 1 and rootfs partition 1. Application
executable should be placed in the rootfs partition. Application data should be placed in the data
partition which is ounted at /data.
The syste has dual boot and rootfs partitions to allow the swupdate tool to do a dual i age
update.

Building from source
Buildroot is used to build the OS and root file syste for the CT650. As the CT650 is sold only to
integrators, the odifications done for the CT650 is not public. Please contact your integrator to
get a copy of the open source files used for your certain version of CT650. If you are an integrator
please contact Dyacon to receive an invitation to the github repo.
To configure Buildroot for the CT650, use the following instructions.
cd ~/
git clone https //github.com/ericrjohn/ct650.git
git clone https //github.com/linux4sam/buildroot-external-
microchip.git
cd buildroot-external-microchip/

Updating the OS on the CT650
Obtain the latest i age fro https://drive.google.co /open?id=10i_kAFYX38-
E tCGV219I2o1ajRuZjvq
Update the CT650 using the following process:
1. Download and extract
the latest i age.
2. Connect to the console
port using a ter inal
progra as described in
the Console Port section
of this docu ent.
3. Attach a USB icro
cable to the unit using
the connector on the
back edge of the board.
If your co puter needs
drivers, the drivers are
located in sa -ba_3.2.3\
driver.
4. Re ove the circuit
board asse bly fro the
case.
5. Using tweezers ora
si ilar tools, activate
progra ing ode by
shorting the PROG
resistor pads while
shorting and releasing
the RESET pads.
Ensure that the short is
held on the PROG pins
until ‘Ro BOOT’ is
seen on the ter inal
and booting stops.
