The Intel® Embedded Development Board 1-N450 is a low-cost development board that is based on the latest generation of Intel® Atom™ processors.
More information on this board
For general information about Board Support Packages, see the Board Support Package (BSP) Developer's Guide. The following information applies to the BSP released for 7.0 "Denzil"
Without modification, the pre-built images contain a 10-day timer. If you boot the pre-built images on target hardware, the hardware will automatically reboot after 10 days at which time the timer will reset itself to another 10-day period. To disable this timer, you must rebuild the BSP image using the Yocto Project

Building the BSP Image from Source
To build the BSP image from source you need to do the following:
- Get the source tarball. You can get the source by downloading the Yocto Project v1.2 release. This release (7.0 "Denzil") contains the core support for this BSP. As an alternative to downloading the BSP tarball, you can also work directly from the meta-intel git repository. For each BSP in the 'meta-intel' repository, there are multiple branches, one corresponding to each major release starting with 'laverne' (0.90), in addition to the latest code which tracks the current master (note that not all BSPs are present in every release). Instead of extracting a BSP tarball at the top level of your yocto build tree, you can equivalently check out the appropriate branch from the meta-intel repository at the same location.
- Once you have the source, add the following to the local.conf file:
# Serial Port Setup for Intel Embedded Development Board 1-N40
SYSLINUX_OPTS_atom-pc = "serial 0 115200"
SERIAL_CONSOLE_atom-pc = "115200 ttyS0"
APPEND_atom-pc = "console=ttyS0,115200 console=tty0"
Downloading and Running the Image
Follow these steps to download the "live" image for this development board and install the image on a USB memory stick from which you can boot the image:
- Download the image
- Use the 'dd' command to copy the image onto the memory stick.
Once you have the bootable image on the memory stick, follow these steps to boot the image on the development board:
- Insert the stand-offs in the bottom of the board so that the board will not make contact with your work surface.
- Install the serial cable and the power switch.
- Plug in a VGA monitor and a keyboard.
- Plug the power supply into the wall.
- Apply power to the board. While the BIOS boot is occurring, press to enter BIOS setup.
- Disable the "Built-in EFI Shell" under "Boot" in the setup menu in "Boot Option Priorities".
- Save your changes and exit the BIOS.
- Hold down the power button for four seconds to power the board off.
- Insert the USB memory stick.
- Plug the USB-to-Serial cable into the USB port on the laptop.
- Configure a terminal emulator on your laptop to use the new USB serial device at 115200 8N1 with no handshaking / flow control.
- Press the power button to turn on the board. You should see serial output streamed to the terminal emulator.
- Login using "root" with no password.
