ddrbin_tool interface has been changed. Additional chip_name argument is now required to modify ddr binary file. Update documentation to be consistent with the new interface. Update BL31 and ROCKCHIP_TPL file paths to match current version of binaries available in the rkbin repository.

SBC-RK3588-AMR Jaguar
|
|
=====================
|
|
|
|
The SBC-RK3588-AMR is a Single Board Computer designed by
|
|
Theobroma Systems for autonomous mobile robots.
|
|
|
|
It provides the following features:
|
|
|
|
* up to 32GB LDDR4
|
|
* up to 128GB on-module eMMC (with 8-bit 1.8V interface)
|
|
* SD card
|
|
* Gigabit Ethernet
|
|
* 1x USB-A 2.0 host
|
|
* PCIe M.2 2230 Key M (Gen 2 1-lane) for WiFi+BT
|
|
* PCIe M.2 2280 Key M (Gen 3 4-lane) for NVMe
|
|
* CAN
|
|
* RS485 UART
|
|
* 2x USB Type-C 3.1 host/device
|
|
* HDMI output
|
|
* 2x camera connectors (MIPI-CSI 2-lane I2C/SPI for IMUs GPIOs)
|
|
* EEPROM
|
|
* Secure Element
|
|
* ATtiny companion controller implementing:
|
|
|
|
- low-power RTC functionality (ISL1208 emulation)
|
|
- fan controller (AMC6821 emulation)
|
|
|
|
* 80-pin Mezzanine connector
|
|
|
|
Here is the step-by-step to boot to U-Boot on SBC-RK3588-AMR Jaguar from Theobroma
|
|
Systems.
|
|
|
|
Get the TF-A and DDR init (TPL) binaries
|
|
----------------------------------------
|
|
|
|
.. prompt:: bash
|
|
|
|
git clone https://github.com/rockchip-linux/rkbin
|
|
cd rkbin
|
|
export RKBIN=$(pwd)
|
|
export BL31=$RKBIN/bin/rk35/rk3588_bl31_v1.47.elf
|
|
export ROCKCHIP_TPL=$RKBIN/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.18.bin
|
|
sed -i 's/^uart baudrate=.*$/uart baudrate=115200/' tools/ddrbin_param.txt
|
|
./tools/ddrbin_tool rk3588 tools/ddrbin_param.txt "$ROCKCHIP_TPL"
|
|
./tools/boot_merger RKBOOT/RK3588MINIALL.ini
|
|
export RKDB=$RKBIN/rk3588_spl_loader_v1.11.112.bin
|
|
|
|
This will setup all required external dependencies for compiling U-Boot. This will
|
|
be updated in the future once upstream Trusted-Firmware-A supports RK3588 or U-Boot
|
|
gains support for open-source DRAM initialization in TPL.
|
|
|
|
Build U-Boot
|
|
------------
|
|
|
|
.. prompt:: bash
|
|
|
|
cd ../u-boot
|
|
make CROSS_COMPILE=aarch64-linux-gnu- jaguar-rk3588_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, remove any SD card, insert a USB-C cable in the
|
|
``DOWNLOAD`` USB Type-C connector (P11) and then power cycle or reset the board
|
|
while pressing the ``BIOS`` (SW2) button. A new USB device should have appeared
|
|
on your PC (check with ``lsusb -d 2207:350b``).
|
|
|
|
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
|
|
./rkdeveloptool db "$RKDB"
|
|
./rkdeveloptool wl 64 ../u-boot-rockchip.bin
