From: Quentin Schulz <quentin.sch...@theobroma-systems.com>
The PX30-µQ7 (Ringneck) is a system-on-module featuring the Rockchip
PX30 in a micro Qseven-compatible form-factor.
PX30-µQ7 features:
* CPU: quad-core Cortex-A35
* DRAM: 2GB dual-channel
* eMMC: onboard eMMC
* SD/MMC
* TI DP83825I 10/100Mbps PHY
* USB:
* USB2.0 dual role port
* 3x USB2.0 host via onboard USB2.0 hub
* Display: MIPI-DSI
* Camera: MIPI-CSI
* onboard 2.4GHz WiFi + Bluetooth module
* Companion Controller: onboard additional Cortex-M0 microcontroller
* RTC
* fan controller
* CAN

+Introduction
+============
+
+The PX30-uQ7 (Ringneck) SoM is a µQseven-compatible (40mmx70mm, MXM-230
+connector) system-on-module from Theobroma Systems[1], 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 STM32 Cortex-M0 companion controller, implementing:
+ - low-power RTC functionality (ISL1208 emulation)
+ - fan controller (AMC6821 emulation)
+ - USB<->CAN bridge controller
+ * 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.
+
+Get the Source and build ATF binary
+===================================
+
+ > git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
+
+Compile the ATF
+===============
+
+ > cd trusted-firmware-a
+ > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=px30 bl31
+ > cp build/px30/release/bl31/bl31.elf ../u-boot/bl31.elf
+
+Compile the U-Boot
+==================
+
+ > cd ../u-boot
+ > make CROSS_COMPILE=aarch64-linux-gnu- ringneck-px30_defconfig all
+
+Flash the image
+===============
+
+Copy u-boot-rockchip.bin to offset 32k for SD/eMMC.
+
+SD-Card
+-------
+
+ > dd if=u-boot-rockchip.bin of=/dev/sdb seek=64
+
+eMMC
+----
+
+rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
+help of the Rockchip loader binary.
+
+ > git clone https://github.com/rockchip-linux/rkdeveloptool
+ > cd rkdeveloptool
+ > autoreconf -i && ./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_v1.16.131.bin
+ > ./rkdeveloptool wl 64 ../u-boot-rockchip.bin
