UP Squared Pro 7000

Overview

UP Squared Pro 7000 is the 3rd generation of palm-sized developer board of UP Boards series. UP Squared Pro 7000 is powered by Intel Alder Lake N (Intel N-series Platform).

For more information about Intel N-series Platform please refer to Alder Lake N.

This board configuration enables kernel support for the UP Squared Pro 7000 boards.

Hardware

General information about the board can be found at the UP Squared Pro 7000 [1] website.

Connections and IOs

Refer to the UP Squared Pro 7000 [1] website for more information.

Programming and Debugging

Use the following procedures for booting an image for an UP Squared Pro 7000 board.

Build Zephyr application

  1. Build a Zephyr application; for instance, to build the hello_world application for UP Squared Pro 7000 board:

    # From the root of the zephyr repository
west build -b up_squared_pro_7000 samples/hello_world

    Note

    A Zephyr EFI image file named zephyr.efi is automatically created in the build directory after the application is built.

Connect Serial Console

Current board configuration assumes that serial console is connected to connector CN14 USB 2.0/UART 1x10P Wafer. Refer to User Manual [2] for description of the connector and location on the board.

Refer to UP Serial Console [3] for additional information about serial connection setup.

Booting the UP Squared Pro 7000 Board using UEFI

Preparing the Boot Device

Prepare a USB flash drive to boot the Zephyr application image on a board.

  1. Format the USB flash drive as FAT32.

    On Windows, open File Explorer, and right-click on the USB flash drive. Select Format.... Make sure in File System, FAT32 is selected. Click on the Format button and wait for it to finish.

    On Linux, graphical utilities such as gparted can be used to format the USB flash drive as FAT32. Alternatively, under terminal, find out the corresponding device node for the USB flash drive (for example, /dev/sdd). Execute the following command:

    $ mkfs.vfat -F 32 <device-node>

    Important

    Make sure the device node is the actual device node for the USB flash drive. Or else you may erase other storage devices on your system, and will render the system unusable afterwards.

  2. Copy the Zephyr EFI image file zephyr/zephyr.efi to the USB drive.

Booting Zephyr on a board

Boot the board to the EFI shell with USB flash drive connected.

  1. Insert the prepared boot device (USB flash drive) into the board.

  2. Connect the board to the host system using the serial cable and configure your host system to watch for serial data. See board’s website for more information.

    Note

    Use a baud rate of 115200.

  3. Power on the board.

  4. When the following output appears, press F7:

    Press <DEL> or <ESC> to enter setup.

  5. From the menu that appears, select the menu entry that describes that particular EFI shell.

  6. From the EFI shell select Zephyr EFI image to boot.

    Shell> fs0:zephyr.efi

  7. When the boot process completes, you have finished booting the Zephyr application image.

Booting the UP Squared Pro 7000 Board over network

Prepare Linux host

  1. Install DHCP, TFTP servers. For example dnsmasq

    $ sudo apt-get install dnsmasq

  2. Configure DHCP server. Configuration for dnsmasq is below:

    # Only listen to this interface
interface=eno2
dhcp-range=10.1.1.20,10.1.1.30,12h

  3. Configure TFTP server.

    # tftp
enable-tftp
tftp-root=/srv/tftp
dhcp-boot=zephyr.efi

    zephyr.efi is a Zephyr EFI binary created above.

  4. Copy the Zephyr EFI image zephyr/zephyr.efi to the /srv/tftp folder.

    $ cp zephyr/zephyr.efi /srv/tftp

  5. TFTP root should be looking like:

    $ tree /srv/tftp
/srv/tftp
└── zephyr.efi

  6. Restart dnsmasq service:

    $ sudo systemctl restart dnsmasq.service

Prepare the board for network boot

  1. Enable PXE network from BIOS settings.

  2. Make network boot as the first boot option.

Booting the board

  1. Connect the board to the host system using the serial cable and configure your host system to watch for serial data. See board’s website for more information.

    Note

    Use a baud rate of 115200.

  2. Power on the board.

  3. Verify that the board got an IP address. Run from the Linux host:

    $ journalctl -f -u dnsmasq
dnsmasq-dhcp[5386]: DHCPDISCOVER(eno2) 00:07:32:52:25:88
dnsmasq-dhcp[5386]: DHCPOFFER(eno2) 10.1.1.28 00:07:32:52:25:88
dnsmasq-dhcp[5386]: DHCPREQUEST(eno2) 10.1.1.28 00:07:32:52:25:88
dnsmasq-dhcp[5386]: DHCPACK(eno2) 10.1.1.28 00:07:32:52:25:88

  4. Verify that network booting is started:

    $ journalctl -f -u dnsmasq
dnsmasq-tftp[5386]: sent /srv/tftp/zephyr.efi to 10.1.1.28

  5. When the boot process completes, you have finished booting the Zephyr application image.
