Flashing Raspberry PI os into emmc memory

For flashing use J103 mini usb connector. You do not need use any jumpers (just connect the SaraKIT USB cable to your PC Computer).

  • Download and run the Windows installer to install the drivers and boot tool.

  • Apply power to the board; Windows should now find the hardware and install the driver.

  • Once the driver installation is complete, run the RPiBoot.exe tool that was previously installed.

  • After a few seconds, the Compute Module eMMC will pop up under Windows as a disk (USB mass storage device).

(for other systems see here https://www.raspberrypi.com/documentation/computers/compute-module.html#setting-up-the-cmio-board)

Download and run Raspberry Pi Imager. With this software you can install your favorite OS or image prepared by us.

if you want to use a ready-made image, download it from here:

do not forget to upload or set the wifi network settings file from here (wifi config) to the boot directory, i.e. to the root directory of the drive connected to Windows.

Note: We have prepared all examples and sound drivers for Raspberry Pi 64 bit, Debian with Bullseye Kernel currently in version 6.1.21 and earlier versions such as 5.15.84. 
If you want to use Debian Bookworm, we recommend updating to at least version 6.1.74 by e.g. sudo rpi-update rpi-6.1.y. We have not been able to compile sound drivers for version 6.1.73 at this time. If there are any problems, please let us know.

Select the system and storage. After selecting the system and storage, click on the settings button:

Be sure to set the username and password here (the use of the PI username is not recommended).
In addition, set access to your WiFi network, without this, the device will not be able to connect to you.
Also, don't forget to check "Enable SSH".

After recording the image to disk, disconnect the power, unplug the USB and reconnect the power to the SaraKIT.

From now on, you can communicate with SaraKIT (Raspberry Pi) using your favorite program, e.g. WinScp or Putty or Visual Studio Code.

How to Find Your Pi’s IP Address from a Windows Computer on the Same Network?

  1. On a Windows computer that’s on the same network as your Pi, launch the command prompt by typing cmd into the search box and pressing Enter.
  2. In the command prompt window, type ping -f raspberrypi (or nslookup raspberrypi):

Regardless of what program you use to connect, you need to install some drivers for new devices offered by SaraKIT:
