Prepare Demo Image
Before starting Ultra-Fast Boot, prepare the boards and software.
All demo images can be downloaded from the "Linux4Sam" page.
Create an SD™ Card With the Demo
You need an SD™ card with at least 1 GB of storage to download the demo image. To minimize the download size, the image is provided in a compressed format. The image contains:
- A FAT32 partition with the at91bootstrap, U-Boot and the Linux® kernel (zImage and .dtb)
- An EXT4 partition for the rootf
To write the compressed image on the SD, download and install balenaEtcher. This tool, which is open-source software, is useful since it enables getting a compressed image as input. More information and extra help are available on the balenaEtcher website.
Flash the Demo (Demo Media is NAND Flash)
Use SAM-BA® software v3.9.x or onwards. You can download SAM-BA software v3.91 from the release page.
Run Script to Flash the Demo
Download the NAND flash demo package for the board.
Extract the demo package.
Run your usual terminal emulator and enter the demo directory.
Ensure that the sam-ba application is in your operating system path so that you can reach it from your demo package directory.
For Microsoft Windows® users: Launch the demo_linux_nandflash.bat file
For Linux users: Launch the demo_linux_nandflash.sh file
This script runs SAM-BA 3 software and the associated QML sam-ba script (demo_linux_nandflash_usb.qml) with proper parameters.
When you reach the end of the flashing process (this will take a few minutes), the following line is written:
-I- === Done. ===
Connect a serial link to the DBGU and open the terminal emulator program as explained just above.
Power cycle the board.
Monitor the system while it's booting on the Liquid Crystal Display (LCD) screen or through the serial line.
