CamView operation procedure
This section describes how to display a video captured with the camera module on the Linux terminal by
executing the Linux application software CamView using the reference design (available for download on
the Kondo Electronics Industry website).
Equipment to prepare
Table 3-1 shows items that need to be prepared, as well as this product, to run the program. Meanwhile,
Table 3-2 lists PC tools required for operation.

Remarks
KEIm-CVSoC development kit
This unit. It contains the AC adapter and the USB Micro-B cable.
HDMI mini cable
USB Micro-AB cable
MicroSD card
USB keyboard
USB mouse
USB hub
Display
The display must have an HDMI port.
PC
Used to write data to the microSD card or for the UART terminal. It
does not require high performance. However, if the PC has no SD
card slot, you will need a USB or other type of SD card reader.

Item
Remarks
Win32 Disk Imager
Used to write the SD image to the SD card.
TeraTerm
Terminal software
Demo software SD image
Download it from the Kondo Electronics Industry website.
Downloading the SD image
Write the Linux image to a microSD card that is inserted into the KEIm-CVSoC camera unit. In this manual,
Win32 Disk Imager is used as a write tool. Version 1.0 is available for download from the following website
as of September 2020. Download and install it according to the installer instructions.
https://sourceforge.net/projects/win32diskimager/
The SD image file “keim-cvsoc-b_devkit_gsrd.7z” is available for download from the following URL page
of the Kondo Electronics Industry website. Download the latest version. The file is compressed in 7z
format, so decompress it using 7zip to get the .img file.

Procedure for writing the SD image
(1) Insert the microSD card into the PC. If the PC has no SD card slot, use a USB card reader.
(2) Start Win32 Disk Imager. Specify the path of the prepared .img file in Image File. Also, select the SD
card drive type from Device.
(3) When you click Write, the following (Confirm overwrite) dialog box appears. Click Yes to start writing
the image.
(4) When the image write is complete, the Complete dialog box appears. Click OK.
(5) Then, execute SD card ejection from the Windows task tray and remove the microSD card from the
SD card slot.
* There has been a change to SD card partition recognition since the Windows update (20H2). If you try
to overwrite the image to an SD card where the reference design is already written, it may fail. In such a
case, delete the SD card partition using the Windows administrative tools or Diskpart tool and write the
image again.
