Software Setup

Cable setup and prerequisites

Here is what you will need to power up and use the board:

  • Linux or Windows PC

  • HummingBoard with Hailo 15 SOM

  • 12V Power adapter (HummingBoard has wide range input of 7V-36V, it is recommended to use 12V power adapter).

  • The micro USB to USB for the console (the HummingBoard has an onboard FTDI chip).

  • IP router or IP switch

Boot select and boot options

You should select the boot source before powering up the board for the first time.

Hailo 15 with HummingBoard has two boot options: serial boot (for recovery) and eMMC boot (the main option). To select a boot option, the DIP switch needs to be modified.

Booting the board:

The board is pre-flashed with a basic yocto image and AI demos.

  1. Serial connection
    Please insert the micro USB into your device. Then, you can refer to Serial Connection to install the necessary serial connection software in Linux/Windows.

  2. Network connection
    The prebuilt image has a preset network configuration with a static IP 10.0.0.1. Connect your PC to the board with a 1GbE RJ45 patch cord and set the static IP of your PC interface to 10.0.0.2.

  3. Optional: Camera connection
    To evaluate the demo application, connect the MIPI-CSI camera to the Hailo 15 SOM MIPI-CSI interface before starting the boot.

  4. Power the board
    Plug in a power supply, and the board will start booting. You will see the boot log in the serial terminal:

Poky (Yocto Project Reference Distro) 4.0.2 hailo15 ttyS1

Use the following default credentials:

  • Login: root

  • Password: root

Running the demo applications

Using GStreamer

Gstreamer is a CLI application that allows you to send, receive, and convert video streams.

  1. Install gstreamer

For Ubuntu/Debian distros:

sudo apt install gstreamer1.0-plugins-ugly gstreamer1.0-plugins-bad gstreamer1.0-libav

For Fedora/RHEL distros:

sudo dnf install gstreamer1 gstreamer1-plugins-base gstreamer1-plugins-good gstreamer1-plugins-bad-free gstreamer1-plugins-bad-free-gtk

For Windows:

  • Download the Installer: Go to the GStreamer official website and download the appropriate installer for your Windows version.

  • Run the Installer: Execute the downloaded file. During installation, select "Complete Installation" to install all basic plugins.

  • Set Environment Variables: To use GStreamer from the command line, add GStreamer to your system's PATH as described here.

For Windows, you might need to configure the Firewall to allow the stream. Make sure that 10.0.0.2 is a private network.

  1. Run the gstreamer pipeline to start receiving a stream.

On your pc In a bash terminal or Windows cmd run:

gst-launch-1.0 -v udpsrc port=5000 address=0.0.0.0 ! application/x-rtp,encoding-name=H264 ! queue ! rtph264depay ! queue ! h264parse ! avdec_h264 ! queue ! videoconvert ! fpsdisplaysink video-sink=autovideosink text-overlay=false sync=false

  1. Run the demo application on the Hailo15 EVK:

Using VLC

Another option is to receive a stream using VLC media player.\

  1. Install VLC

    For Ubuntu/Debian distros:

    For Fedora/RHEL distros:

    For Windows:

  • Download the Installer: Go to the VLC official website and download the appropriate installer for your Windows version.

  • Run the Installer: Execute the downloaded file. During installation, select "Complete Installation" to install all basic plugins.

For Windows, you might need to configure the Firewall to allow the stream. Make sure that 10.0.0.2 is a private network.

  1. Create a stream configuration file stream.sdp with the following content:

v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Name
c=IN IP4 10.0.0.2
t=0 0
a=tool:libavformat 58.20.100
m=video 5000 RTP/AVP 96
a=rtpmap:96 H264/90000

  1. Open the stream.sdp in the vlc using the Media -> Open File tab.

  2. Run the demo application on the target:

Flashing an eMMC

By default, when Linux is booted from eMMC, the eMMC root partition is mounted, which makes it difficult to reflash. The u-boot menu has special entries that allow you to reflash eMMC from the TFTP server on your computer.

  1. Run an HTTP server on port 80 in the directory with the image

  1. Reset the board. In the u-boot menu, select Update eMMC (wic) from HTTP

  2. The Board will grub a new image from the TFTP server and flash it to the eMMC.

Flashing QSPI flash

Reflashing QSPI is only possible under Linux.

  1. Download the flashing tool and install it into your system.

  1. Set the S3 switch to the Serial download mode.

  1. Close the serial terminal on your PC.

  2. Reset the board.

  3. Upload the uart flashing firmware into the SOM:

  1. Reflash QSPI content:

Restoring corrupted eMMC u-boot image.

If the eMMC content is blank, the SPL bootloader will fall back to the UART Y-Modem mode. This will allow the user to send a new u-boot-tfa.itb file over the serial connection and then restore the eMMC content with tftp. If you see this in the boot log, the board expects u-boot over the uart. You can skip the reflashing u-boot env part.

U-Boot SPL 2022.01 (Feb 04 2024 - 18:42:25 +0000)
Loading Environment from SPIFlash... OK
U-Boot SPL boot source uart
CCCCCCCCCC

However, if the u-boot-tfa.itb was corrupted, the board will load a corrupted file and get stuck booting. To force SPL to the UART upload mode, the u-boot env has to be reflashed.

Modifying u-boot env to force uart boot mode

  1. Modify the u-boot env to set uart boot mode for the SPL:

Find the line spl_boot_source=mmc2 and replace it with spl_boot_source=uart in the file u-boot-initial-env-uart.

  1. Set the S3 switch to the Serial download mode.

  1. Close the serial terminal on your PC.

  2. Reset the board.

  3. Upload the uart flashing firmware into the SOM:

  1. Reflash u-boot environment:

  1. Set the S3 switch back to the eMMC boot.

  1. Open the serial connection and reset the boot. The board will boot to the SPL and expect the u-boot image to be transferred over the serial.

Uploading u-boot over uart

The SPL waits for the Y-modem transfer to upload the u-boot into the RAM. The latest minicom already has a built-in Y-modem transfer function. With minicom, press Ctrl+A, then S, select ymodem, and then select file u-boot-tfa.itb. Note: the transfer can take a few minutes. As soon as the u-boot is completely transferred, you will see the same u-boot entries, and you can restore eMMC content with tftp.

Restoring u-boot env

If you previously modified a u-boot env to force a serial mode, you need to restore it.

  1. Set the S3 switch to the Serial download mode.

  1. Close the serial terminal on your PC.

  2. Reset the board.

  3. Upload the uart flashing firmware into the SOM:

  1. Reflash u-boot environment:

  1. Set the S3 switch back to the eMMC boot:

  1. Open the serial connection and reset the boot. The board will boot to the SPL and expect the u-boot image to be transferred over the serial.
