Create a SD card with the demo

You need a 1 GB SD card (or more) and to download the image of the demo. The image is compressed to reduce the amount of data to download. This image contains:

  • a FAT32 partition with the AT91Bootstrap, U-Boot and the Linux Kernel (zImage and dtb).
  • an EXT4 partition for the rootfs.

Multi-platform procedure

To write the compressed image on the SD card, you will have to download and install balenaEtcherhttps://www.linux4sam.org/pub/TWiki/TWikiDocGraphics/external-link.gif. This tool, which is an Open Source software, is useful since it allows to get a compressed image as input. More information and extra help available on the balenaEtcher websitehttps://www.linux4sam.org/pub/TWiki/TWikiDocGraphics/external-link.gif.

  • Insert your SD card and launch Etcher:

Etcher selection step

  1. Select the demo image. They are marked as "SD Card image" in the demo table above.
    Note that you can select a compressed image (like the demos available here). The tool is able to decompress files on the fly
  2. Select the device corresponding to your SD card (Etcher proposes you the devices that are removable to avoid erasing your system disk)
  3. Click on the Flash! button
  4. On Linux, Etcher finally asks you to enter your root password because it needs access to the hardware (your SD card reader or USB to SD card converter)
  5. then the flashing process begins followed by a verification phase (optional)

Etcher flashing done!

  • Once writing done, Etcher asks you if you want to burn another demo image:
