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
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.
Format the USB flash drive as FAT32.
On Windows, open
File Explorer
, and right-click on the USB flash drive. SelectFormat...
. Make sure inFile System
,FAT32
is selected. Click on theFormat
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.
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.
Insert the prepared boot device (USB flash drive) into the board.
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.
Power on the board.
When the following output appears, press F7:
Press <DEL> or <ESC> to enter setup.
From the menu that appears, select the menu entry that describes that particular EFI shell.
From the EFI shell select Zephyr EFI image to boot.
Shell> fs0:zephyr.efi
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
Install DHCP, TFTP servers. For example
dnsmasq
$ sudo apt-get install dnsmasq
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
Configure TFTP server.
# tftp enable-tftp tftp-root=/srv/tftp dhcp-boot=zephyr.efi
zephyr.efi
is a Zephyr EFI binary created above.Copy the Zephyr EFI image
zephyr/zephyr.efi
to the/srv/tftp
folder.$ cp zephyr/zephyr.efi /srv/tftp
TFTP root should be looking like:
$ tree /srv/tftp /srv/tftp └── zephyr.efi
Restart
dnsmasq
service:$ sudo systemctl restart dnsmasq.service
Prepare the board for network boot
Enable PXE network from BIOS settings.
Make network boot as the first boot option.
Booting the board
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.
Power on the board.
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
Verify that network booting is started:
$ journalctl -f -u dnsmasq dnsmasq-tftp[5386]: sent /srv/tftp/zephyr.efi to 10.1.1.28
When the boot process completes, you have finished booting the Zephyr application image.
