Also it's available to connect XU4 / C2 / C1+ using a micro-USB cable and a HDMI cable described in Option 2.

Since ODROID C2/C1+ is discontinued, the two kinds of link boards are no more produced.

Option 1 ( NOT AVAILABLE )

Option 2

With VU7A+, you can enjoy sound with a stereo speaker or an audio earjack.

Please note that the speaker output turns off when an earjack is plugged in.

You can find out the two link boards that link ODROID C2/C1+ and Vu7A in the below example pictures. Since ODROID C2/C1+ is discontinued, the two kinds of link boards are NOT able to purchase.

sudo vim /media/boot/boot.ini
Auto Detection

With the version 4.14.32-126 or higher version,
XU4 automatically detects the resolution of VU7A+ as 1024×600 with HDMI without any change of boot.ini.
VU7A+ model provides HDMI functionality, so you don't need modify boot.ini to switch into DVI as you do with VU7+.

# --- HDMI / DVI Mode Selection ---
# ------------------------------------------
# - HDMI Mode
setenv vout "hdmi"
# - DVI Mode (disables sound over HDMI as per DVI compat)
# setenv vout "dvi"
Manual Setting

If you use the lower version than 4.14.32-126, boot.ini modification is required as following.
