=================
|
|
|
|
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
|
|
* MIPI-DSI/LVDS
|
|
* MIPI-CSI
|
|
* 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)
|
|

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
|
|
-----------------------------------
|
|
|
|
.. prompt:: bash
|
|
|
|
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
|
|
------------------
|
|
|
|
.. prompt:: bash
|
|
|
|
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.
|
|
|
|
SD-Card
|
|
~~~~~~~
|
|
|
|
.. prompt:: bash
|
|
|
|
dd if=u-boot-rockchip.bin of=/dev/sdX seek=64
|
|
|
|
.. note::
|
|
|
|
Replace ``/dev/sdX`` to match your SD card kernel device.
|
|
|
|
eMMC
|
|
~~~~
|
|
|
|
``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``:
|
|
|
|
.. prompt:: bash
|
|
|
|
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
