PX30-uQ7 Ringneck

The PX30-uQ7 (Ringneck) SoM is a µQseven-compatible (40mmx70mm, MXM-230 connector) system-on-module from Theobroma Systems, featuring the Rockchip PX30.

It provides the following feature set:

  • up to 4GB DDR4

  • up to 128GB on-module eMMC (with 8-bit 1.8V interface)

  • SD card (on a baseboard) via edge connector

  • Fast Ethernet with on-module TI DP83825I PHY



  • USB

    • 1x USB 2.0 dual-role

    • 3x USB 2.0 host

  • on-module companion controller (STM32 Cortex-M0 or ATtiny), implementing:

    • low-power RTC functionality (ISL1208 emulation)

    • fan controller (AMC6821 emulation)

    • USB<->CAN bridge controller (STM32 only)

  • on-module Espressif ESP32 for Bluetooth + 2.4GHz WiFi

  • on-module NXP SE05x Secure Element

Here is the step-by-step to boot to U-Boot on PX30-uQ7 Ringneck from Theobroma Systems.

Get the Source and build ATF binary

git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
cd trusted-firmware-a
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=px30 bl31
export BL31=$PWD/build/px30/release/bl31/bl31.elf

Compile the U-Boot

cd ../u-boot
make CROSS_COMPILE=aarch64-linux-gnu- ringneck-px30_defconfig all

This will build u-boot-rockchip.bin which can be written to an MMC device (eMMC or SD card).

Flash the image

Copy u-boot-rockchip.bin to offset 32k for SD/eMMC.


dd if=u-boot-rockchip.bin of=/dev/sdX seek=64


Replace /dev/sdX to match your SD card kernel device.


rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with help of the Rockchip loader binary.

To enter the USB flashing mode on Haikou baseboard, remove any SD card, insert a micro-USB cable in the Q7 USB P1 connector (P8), move SW5 switch into BIOS Disable mode, power cycle or reset the board and move SW5 switch back to Normal Boot mode. A new USB device should have appeared on your PC (check with lsusb -d 2207:330d).

To flash U-Boot on the eMMC with rkdeveloptool:

git clone https://github.com/rockchip-linux/rkdeveloptool
cd rkdeveloptool
autoreconf -i && CPPFLAGS=-Wno-format-truncation ./configure && make
git clone https://github.com/rockchip-linux/rkbin.git
cd rkbin
./tools/boot_merger RKBOOT/PX30MINIALL.ini
cd ..
./rkdeveloptool db rkbin/px30_loader_v2.08.135.bin
./rkdeveloptool wl 64 ../u-boot-rockchip.bin
