BeagleV Starlight and the StarFive JH7100 SoC has been merged into upstream buildroot. Instructions are available in buildroot master branch.
This builds a complete RISC-V cross-compile toolchain for the StarFiveTech JH7100 SoC. It also builds U-boot and a flattened image tree (FIT) image with a OpenSBI binary, linux kernel, device tree, ramdisk and rootdisk for the Starlight development board.
Recommend OS: Ubuntu 16.04/18.04
After installing the operating system. Do not forget updating all packages
$sudo apt update
$sudo apt upgrade
Install required additional packages.
$ sudo apt-get install autoconf automake autotools-dev bc bison xxd \
build-essential curl flex gawk gdisk git gperf libgmp-dev \
libmpc-dev libmpfr-dev libncurses-dev libssl-dev libtool \
patchutils python screen texinfo unzip zlib1g-dev device-tree-compiler
Checkout this repository (the multimedia branch: JH7100_starlight_multimedia
). Then you will need to checkout all of the linked
submodules using:
$ git checkout --track origin/JH7100_starlight_multimedia
$ git submodule update --init --recursive
This will take some time and require around 7GB of disk space. Some modules may fail because certain dependencies don’t have the best git hosting.
Once the submodules are initialized, 4 submodules buildroot
, HiFive_U-boot
,
linux
and opensbi
need checkout to corresponding branches manually, seeing .gitmodule
$ cd buildroot && git checkout --track origin/starlight_multimedia && cd ..
$ cd HiFive_U-Boot && git checkout --track origin/Fedora_JH7100_upstream_devel && cd ..
$ cd linux && git checkout --track origin/beaglev-5.13.y_multimedia && cd ..
$ cd opensbi && git checkout --track origin/master && cd ..
After update submodules, run make
or make -jx
and the complete toolchain and
fw_payload.bin.out & image.fit will be built. The completed build tree will consume about 18G of
disk space.
By default, the above generated image does not contain VPU module(wave511, the video hard decode driver and openmax-il framework library). The following instructions will add VPU module according to your requirement:
$ make -jx
$ make vpubuild
$ rm -rf work/buildroot_initramfs/images/rootfs.tar
$ make -jx
Copy files fw_payload.bin.out and image.fit to tftp installation path to use
Path:
freelight-u-sdk/work/image.fit
freelight-u-sdk/work/opensbi/platform/generic/firmware/fw_payload.bin.out
The other make command:
make linux-menuconfig # Kernel menuconfig
make uboot-menuconfig # uboot menuconfig
make buildroot_initramfs-menuconfig # initramfs menuconfig
make buildroot_rootfs-menuconfig # rootfs menuconfig
The default display framework is Framebuffer
. If switch to DRM
display framework (drm to hdmi
pipeline):
1. Disable the below kernel config
CONFIG_FB_STARFIVE
CONFIG_FB_STARFIVE_HDMI_TDA998X
CONFIG_FB_STARFIVE_VIDEO
CONFIG_NVDLA
CONFIG_FRAMEBUFFER_CONSOLE
2. Enable the below kernel config:
CONFIG_DRM_I2C_NXP_TDA998X
CONFIG_DRM_I2C_NXP_TDA9950
CONFIG_DRM_STARFIVE
Note: when use DRM to hdmi pipeline, please make sure CONFIG_DRM_STARFIVE_MIPI_DSI is disable, or will cause color abnormal.
If switch to DRM
display framework (drm to mipi
pipeline):
based on the above drm to hdmi pipeline config, enable the below kernel config:
CONFIG_PHY_M31_DPHY_RX0
CONFIG_DRM_STARFIVE_MIPI_DSI
After the Starlight is properly connected to the serial port cable, network cable and power cord turn on the power from the wall power socket to power on the Starlight and you will see the startup information as follows:
bootloader version: 210209-4547a8d
ddr 0x00000000, 1M test
ddr 0x00100000, 2M test

Press any key as soon as it starts up to enter the upgrade menu. In this menu, you can update uboot

select the function:
Type «0» to update the uboot file fw_payload.bin.out via Xmodem mode, and then Type «1» to exit Flash Programming.
After you will see the information StarFive #
,select the installation path
and install image.fit through TFTP:
setenv fileaddr a0000000; setenv serverip 192.168.xxx.xxx;tftpboot ${fileaddr} ${serverip}:image.fit;bootm start ${fileaddr};bootm loados ${fileaddr};booti 0x80200000 0x86100000:${filesize} 0x86000000
When you see the buildroot login:
