From: Quentin Schulz <quentin.schulz at theobroma-systems.com>
JAGUAR is a Single-Board Computer (SBC) based around the rk3588 SoC and
is targeting Autonomous Mobile Robots (AMR).
It features:
* LPDDR4X (up to 16GB)
* 1Gbps Ethernet on RJ45 connector (KSZ9031 or KSZ9131)
* PCIe 3.0 4-lane on M.2 M-key connector
* PCIe 2.1 1-lane on M.2 E-key
* USB 2.0 on M.2 E-key
* 2x USB3 OTG type-c ports with DP Alt-Mode
* USB2 host port
* HDMI output
* 2x camera connectors, each exposing:
* 2-lane MIPI-CSI
* 1v2, 1v8, 2v8 power rails
* I2C bus
* GPIOs
* PPS input
* CAN
* RS485 UART
* FAN connector
* SD card slot
* eMMC (up to 256GB)
* RTC backup battery
* Companion microcontroller
* ISL1208 RTC emulation
* AMC6821 PWM emulation
* On/off buzzer control
* Secure Element
* 80-pin Mezzanine connector for daughterboards:
* GPIOs
* 1Gbps Ethernet
* PCIe 2.1 1-lane
* 2x 2-lane MIPI-CSI
* ADC channel
* I2C bus
* PWM
* UART
* SPI
* SDIO
* CAN
* I2S
* 1v8, 3v3, 5v0, dc-in (12-24V) power rails
The Device Tree comes from next-20240110 Linux kernel.

+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_v1.38.elf
+ export ROCKCHIP_TPL=$RKBIN/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_v1.11.bin
+ sed -i 's/^uart baudrate=.*$/uart baudrate=115200/' tools/ddrbin_param.txt
+ ./tools/ddrbin_tool 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.

+``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
