ODROID C4

The ODROID-C4 is a single-board computer from Hardkernel powered by the Amlogic S905X3 SoC. It offers a compact form factor with capable processing power at a low price point.

Key Features

• Amlogic S905X3: quad Cortex-A55 at up to 1.9 GHz
• Mali-G31 MP2 GPU
• 4 GB DDR4 RAM
• eMMC module socket and MicroSD card slot
• Gigabit Ethernet
• 4x USB 3.0, 1x USB 2.0 OTG
• HDMI 2.0 (up to 4K@60)
• 40-pin GPIO header
• IR receiver

Building/installing an image

1. git clone https://github.com/YoeDistro/yoe-distro.git
2. cd yoe-distro
3. . ./envsetup.sh odroid-c4
4. yoe_setup
5. bitbake yoe-simple-image
6. Insert SD card
7. lsblk (note SD card device, and substitute for /dev/sdX below)
8. yoe_install_image /dev/sdX yoe-simple-image
9. sudo eject /dev/sdX
10. Install SD card in the ODROID-C4 and apply power

Serial Console

The debug UART is available on the 40-pin GPIO header. Connect a 3.3V USB-to-serial adapter:

• Pin 6 (GND) to GND
• Pin 8 (TX) to RX
• Pin 10 (RX) to TX

Serial settings: 115200 baud, 8N1.

Although ODROID provides a serial console adapter, many of us have rPi-style flying-lead cables on hand. These can be attached directly to the connector on the ODROID. If you have a HAT on the board, then an option is to solder a small header on the bottom as shown below.
