The Radxa ROCK 4D is a compact single-board computer (SBC) featuring
numerous top-tier functions, features, and expansion options.
Equipped with the Rockchip RK3576 or RK3576J SoC, the ROCK 4D boasts an
octa-core CPU (4x Cortex-A72 + 4x Cortex-A53), Mali-G52 GPU, and a
powerful 6 TOPS NPU, making it ideal for AI and multimedia tasks.
Features tested on a Radxa ROCK 4D v1.112:
- SPI Flash boot
- Ethernet
ROCK 4D boards with SPI Flash is configured to boot from FSPI0->UFS->USB,
or directly from USB when the MASKROM button is pressed, booting
directly from SD-card is not possible on these boards.
