board: rockchip: Add support for 9Tripod X3568 v4

2026-07-10T08:52:20Z

The 9Tripod X3568 v4 is an RK3568-based SBC, just like the RK3568-EVB. It always uses soldered connections between the X3568CV2/X3568CV3/X3568CV4 core board and the X3568bv4 I/O board. The differences between the core boards - PCB size, layout - CPU (RK3568B2/RK3568J) - Memory type (DDR4/LPDDR4/LPDDR4X) and size - eMMC size - DSI/EDP resistor values Although the components vary, they maintain full compatibility. The X3568 board has multiple hardware revisions, and we currently support v4 (I/O board). Specification: - SoC: RockChip RK3568 ARM64 (4 cores) - eMMC: 16-128 GB - RAM: 2-16 GB - Power: DC 12V 2A - Ethernet: 2x YT8521SC RGMII (10/100/1000 Mbps) - Wireless radio: 802.11b/g/n/ac/ax dual-band - LED: Power: AlwaysOn User: GPIO - Button: VOL+: SARADC/0 <35k µV> VOL-: SARADC/0 <450k µV> Power/Reset: PMIC RK809 - CAN CAN/1: 4-pin (PH 2.0) - PWM PWM/4: Backlight DSI/0 DSI/1 PWM/7: IR Receiver [may not install] - UART: UART/2: Debug TTL - 1500000 8N1 (1.25mm) UART/3: TTL (PH 2.0) UART/4: TTL (PH 2.0) UART/8: AP6275S Bluetooth UART/9: TTL (PH 2.0) - I2C: I2C/0: PMIC RK809 I2C/1: Touchscreen DSI/0 DSI/1 I2C/4: Camera I2C/5: RTC@51 PCF8563 - I2S: I2S/0: miniHDMI Sound I2S/1: RK809 Audio Codec I2S/3: AP6275S Bluetooth Sound - SDMMC: SDMMC/0: microSD (TF) slot SDMMC/2: AP6275S SDIO WiFi card - Camera: 1x CSI - Video: miniHDMI / DSI0 (MIPI/LVDS) / DSI1 (MIPI/EDP) - Audio: miniHDMI / MIC on-board / Speaker / SPDIF / 3.5mm Headphones / AP6275S Bluetooth - USB: USB 2.0 HOST x2 USB 2.0 HOST x3 (4-pin) USB 2.0 OTG x1 (shared with USB 3.0 OTG/HOST) [slot may not install] USB 3.0 HOST x1 USB 3.0 OTG/HOST x1 - SATA: 1x SATA 3.0 with Power/4-pin [slot may not install] - PCIe: 1x PCIe 3.0 x2 (x4 connector) [power/clock/slot may not install] Link: - https://appletsapi.52solution.com/media/X3568V4%E5%BC%80%E5%8F%91%E6%9D%BF%E7%A1%AC%E4%BB%B6%E6%89%8B%E5%86%8C.pdf - https://blog.gov.cooking/archives/research-ninetripod-x3568-v4-and-flash.html Signed-off-by: Coia Prant Reviewed-by: Quentin Schulz Link: https://patch.msgid.link/20260709185101.2149485-1-coiaprant@gmail.com Signed-off-by: Quentin Schulz
