When one attempts to build Tiger and Jaguar from the same directory, because Tiger will set the IOMUX to 2 but Jaguar doesn't reset it, Jaguar will have IOMUX set to 2 if built after Tiger. This isn't an issue if in separate directories or building Tiger after Jaguar because the default if missing from the configuration file is 0. Let's make it explicit that the iomux is 0 for Jaguar.

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 DDR init (TPL) binary
|
|
-------------------------
|
|
|
|
.. prompt:: bash
|
|
|
|
git clone https://github.com/rockchip-linux/rkbin
|
|
cd rkbin
|
|
export ROCKCHIP_TPL=$(readlink -f bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v*.bin | head -1)
|
|
sed -i 's/^uart baudrate=.*$/uart baudrate=115200/' tools/ddrbin_param.txt
|
|
sed -i 's/^uart iomux=.*$/uart iomux=0/' tools/ddrbin_param.txt
|
|
python3 ./tools/ddrbin_tool.py rk3588 tools/ddrbin_param.txt "$ROCKCHIP_TPL"
|
|
./tools/boot_merger RKBOOT/RK3588MINIALL.ini
|
|
export RKDB=$(readlink -f rk3588_spl_loader_v*.bin | head -1)
|
|
|
|
This will setup all required external dependencies for compiling U-Boot. This will
|
|
be updated in the future once U-Boot gains support for open-source DRAM initialization
|
|
in TPL.
|
|
|
|
Get TF-A
|
|
--------
|
|
|
|
There are two possible options, pick one or the other. Note that the instructions need
|
|
to be run from the ``rkbin`` directory.

Prebuilt binary from Rockchip

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. prompt:: bash
|
|
|
|
export BL31=$(readlink -f bin/rk35/rk3588_bl31_v*.elf | head -1)
|
|
|
|
Upstream
|
|
~~~~~~~~
|
|
|
|
.. prompt:: bash
|
|
|
|
cd ../
|
|
git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
|
|
cd trusted-firmware-a
|
|
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3588 bl31
|
|
export BL31=$PWD/build/rk3588/release/bl31/bl31.elf
|
|
|
|
Build U-Boot
|
|
------------
|
|
|
|
.. prompt:: bash
|
|
|
|
cd ../u-boot
|
|
make CROSS_COMPILE=aarch64-linux-gnu- jaguar-rk3588_defconfig all
|
|
|
|
.. note::
|
|
If using upstream TF-A, one should disable ``SPL_ATF_NO_PLATFORM_PARAM`` symbol in
|
|
U-Boot config (via e.g. ``make CROSS_COMPILE=aarch64-linux-gnu- menuconfig``) which
|
|
will, among other things, enable console output in TF-A.
|
|
|
|
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
