Hi Willian
Same step as document getting_start_720 ch3.
Connect UART0, you cam see two com port, Open teraterm and connect the first one com port with speed 115200.
Setup terminal New-line: Receive: "LF".
Press Reset BTN, You should see the logs .
Remember that, when you connect com port with teraterm, The flash_programmer.py can't work in the same time.
Must disconnect or exit teraterm, then execute flash_programmer.py .

Thanks Its working now. I am able see the logs in Teraterm and Minicom also
Below is the log
Welcome to minicom 2.7.1
OPTIONS: I18nCompiled on Aug 13 2017, 15:25:34.Port /dev/ttyUSB0, 15:47:01Press CTRL-A Z for help on special keys1. SPI-NOR2. SPI-NAND3. USB4. UART(Xmodem)Please select boot mode[1-4]:BOOT MODE: SPI-NANDBoot from Block 0: Image header failed! (wrong magic number)Boot from Block 1: Image header failed! (wrong magic number)Boot from Block 2: Image header failed! (wrong magic number)Is this error normal ???
Can someone please guide on which mode to use , Is there any document on each mode?
Hi Willian
Please check the bin file you flash_programmer to SPI_NAND.
You can try flash-programmer attach bin file.
Unzip and >python flash_programmer.py -a flash_image_solution_companion.bin
I flashed "flash_image_solution_companion.bin" and now its giving me the below log
Current TDC Temperature is about [47]Is this the correct output??
I am not able to write anything or even press enter while using minicom. Can you please confirm that its the right output
Thanks

Hi William
Output is correct.
KL720 running in companion mode now. And could control by PC Host with USB.
You can follow the document ch4 to try the host_lib example.
When I follow the guide I get the below error logs when using the command cmake -DBUILD_OPENCV_EX=on ..
will@will:~/New_project/kl720/host_lib_v1.0.0/host_lib/build$ cmake -DBUILD_OPENCV_EX=on ..

CMake Error at example/CMakeLists.txt:9 (find_package):
By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "OpenCV", but
CMake did not find one.

What is your OS?
If you build host_lib with WIndows MSYS,
follow document step install mingw-w64-x86_64-opencv-3.4.1-1-any.pkg.tar.xz.zip and setup Environment Variables.
use command "cmake -G"MSYS Makefiles" -DBUILD_OPENCV_EX=on .."
If ubuntu ,install opencv3.4.x first,
Then use command : "cmake -DBUILD_OPENCV_EX=on .."
...
My os is ubuntu 18.04
Ubuntu need install opencv too, there is steps for reference
git clone https://github.com/opencv/opencv.git
cd opencv
git checkout 6d4f66472e14b29b8e1623859cfebfdc67f677c3
mkdir build
cd build
cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D CMAKE_BUILD_TYPE=Release -D WITH_TBB=ON -D WITH_V4L=ON -D WITH_LIBV4L=ON -D WITH_CUDA=OFF -D WITH_OPENGL=ON ..
make -j8
sudo make install
sudo sh -c 'echo "/usr/local/lib" >> /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
#check version
pkg-config --modversion opencv
