|
|
|
+
|
|
|
+<blockquote><em>[Win32DiskImager] is designed to write a raw disk image to a removable device or backup a removable device to a raw image file. It is very useful for embedded development, namely Arm development projects (Android, Ubuntu on Arm, etc). -<a href="https://sourceforge.net/projects/win32diskimager/" target="_blank">https://sourceforge.net/projects/win32diskimager/</a></em></blockquote>

+<h2>Creating the Base Image</h2>
|
|
|
+
|
|
|
+<ol>
|
|
|
+ <li>Insert the SD card into the Windows PC</li>
|
|
|
+ <li>Download Win32DiskImager <a href="https://sourceforge.net/projects/win32diskimager/files/Archive/Win32DiskImager-1.0.0-binary.zip/download" target="_blank">Download</a></li>
|
|
|
+ <li>Extract the downloaded .zip file</li>
|
|
|
+ <li>Run Win32DiskImager.exe</li>
|
|
|
+ <li>Select the SD card from the Device dropdown</li>
|
|
|
+ <li>Click the folder icon > Browse to a location to save the SD card image > Enter a file name > Click Open</li>
|
|
|
+ <li>Click the Read button at the bottom of the application window</li>
|
|
|
+ <li>Wait while the contents of the SD card image is read</li>
|
|
|
+</ol>
|
|
|
+
|
|
|
+<h2><span>What is PiShrink?</span></h2>
|
|
|
+
|
|
|
+<blockquote><em>PiShrink is a bash script that automatically shrinks a pi image that will then resize to the max size of the SD card on boot. This will make putting the image back onto the SD card faster and the shrunk images will compress better. In addition the shrunk image can be compressed with gzip and xz to create an even smaller image. Parallel compression of the image using multiple cores is supported. -<a href="https://github.com/Drewsif/PiShrink" target="_blank">https://github.com/Drewsif/PiShrink</a></em></blockquote>
