| 4 | ================= |
| 5 | |
| 6 | The PX30-uQ7 (Ringneck) SoM is a ยตQseven-compatible (40mmx70mm, MXM-230 |
| 7 | connector) system-on-module from Theobroma Systems, featuring the Rockchip PX30. |
| 8 | |
| 9 | It provides the following feature set: |
| 10 | |
| 11 | * up to 4GB DDR4 |
| 12 | * up to 128GB on-module eMMC (with 8-bit 1.8V interface) |
| 13 | * SD card (on a baseboard) via edge connector |
| 14 | * Fast Ethernet with on-module TI DP83825I PHY |
| 15 | * MIPI-DSI/LVDS |
| 16 | * MIPI-CSI |
| 17 | * USB |
| 18 | |
| 19 | - 1x USB 2.0 dual-role |
| 20 | - 3x USB 2.0 host |
| 21 | |
| 22 | * on-module companion controller (STM32 Cortex-M0 or ATtiny), implementing: |
| 23 | |
| 24 | - low-power RTC functionality (ISL1208 emulation) |
| 25 | - fan controller (AMC6821 emulation) |
| 26 | - USB<->CAN bridge controller (STM32 only) |
| 27 | |
| 28 | * on-module Espressif ESP32 for Bluetooth + 2.4GHz WiFi |
| 29 | * on-module NXP SE05x Secure Element |

| 31 | Here is the step-by-step to boot to U-Boot on PX30-uQ7 Ringneck from Theobroma |
| 32 | Systems. |
| 33 | |
| 34 | Get the Source and build ATF binary |
| 35 | ----------------------------------- |
| 36 | |
| 37 | .. prompt:: bash |
| 38 | |
| 39 | git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git |
| 40 | cd trusted-firmware-a |
| 41 | make CROSS_COMPILE=aarch64-linux-gnu- PLAT=px30 bl31 |
| 42 | export BL31=$PWD/build/px30/release/bl31/bl31.elf |
| 43 | |
| 44 | Compile the U-Boot |
| 45 | ------------------ |
| 46 | |
| 47 | .. prompt:: bash |
| 48 | |
| 49 | cd ../u-boot |
| 50 | make CROSS_COMPILE=aarch64-linux-gnu- ringneck-px30_defconfig all |
| 51 | |
| 52 | This will build ``u-boot-rockchip.bin`` which can be written to an MMC device |
| 53 | (eMMC or SD card). |
| 54 | |
| 55 | Flash the image |
| 56 | --------------- |
| 57 | |
| 58 | Copy ``u-boot-rockchip.bin`` to offset 32k for SD/eMMC. |
| 59 | |
| 60 | SD-Card |
| 61 | ~~~~~~~ |
| 62 | |
| 63 | .. prompt:: bash |
| 64 | |
| 65 | dd if=u-boot-rockchip.bin of=/dev/sdX seek=64 |
| 66 | |
| 67 | .. note:: |
| 68 | |
| 69 | Replace ``/dev/sdX`` to match your SD card kernel device. |
| 70 | |
| 71 | eMMC |
| 72 | ~~~~ |
| 73 | |
| 74 | ``rkdeveloptool`` allows to flash the on-board eMMC via the USB OTG interface |
| 75 | with help of the Rockchip loader binary. |
| 76 | |
| 77 | To enter the USB flashing mode on Haikou baseboard, remove any SD card, insert a |
| 78 | micro-USB cable in the ``Q7 USB P1`` connector (P8), move ``SW5`` switch into |
| 79 | ``BIOS Disable`` mode, power cycle or reset the board and move ``SW5`` switch |
| 80 | back to ``Normal Boot`` mode. A new USB device should have appeared on your PC |
| 81 | (check with ``lsusb -d 2207:330d``). |
| 82 | |
| 83 | To flash U-Boot on the eMMC with ``rkdeveloptool``: |
| 84 | |
| 85 | .. prompt:: bash |
| 86 | |
| 87 | git clone https://github.com/rockchip-linux/rkdeveloptool |
| 88 | cd rkdeveloptool |
| 89 | autoreconf -i && CPPFLAGS=-Wno-format-truncation ./configure && make |
| 90 | git clone https://github.com/rockchip-linux/rkbin.git |
| 91 | cd rkbin |
| 92 | ./tools/boot_merger RKBOOT/PX30MINIALL.ini |
| 93 | cd .. |
| 94 | ./rkdeveloptool db rkbin/px30_loader_v2.08.135.bin |
| 95 | ./rkdeveloptool wl 64 ../u-boot-rockchip.bin |
