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
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
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
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
:
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
