Radxa ROCK Pi 4B

The ROCK Pi 4B is a single-board computer from Radxa powered by the Rockchip RK3399 SoC. It offers a Raspberry Pi-like form factor with significantly more processing power.

Key Features

• Rockchip RK3399: dual Cortex-A72 at 1.8 GHz + quad Cortex-A53 at 1.4 GHz
• Mali-T860MP4 GPU
• 1/2/4 GB LPDDR4 RAM
• eMMC socket and MicroSD card slot
• M.2 connector for NVMe SSD
• Gigabit Ethernet
• 802.11ac WiFi and Bluetooth 5.0
• USB 3.0, USB 2.0, USB-C (with DisplayPort alt-mode)
• HDMI 2.0 (up to 4K@60)
• MIPI DSI and CSI interfaces
• 40-pin GPIO header (Raspberry Pi compatible)

Building/installing an image

1. git clone https://github.com/YoeDistro/yoe-distro.git
2. cd yoe-distro
3. . ./envsetup.sh rockpi-4b
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 ROCK Pi 4B and apply power

Serial Console

The debug UART is available on the 40-pin GPIO header (pins 6/8/10). 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: 1500000 baud, 8N1. Note the high baud rate — make sure your serial adapter supports it.
