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 BeagleV 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 \
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 (default branch:starfive). Then you will need to checkout all of the linked submodules using:
$ 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 modulesbuildroot,HiFive_U-boot,linux and opensbi need checkout to starfive branch manually.
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.
Copy file fw_payload.bin.out and image.fit to installation path to use
Path：
/freelight-u-sdk/work/image.fit
/freelight-u-sdk/work/opensbi/platform/starfive/vic7100/firmware/fw_payload.bin.out
After the BeagleV™ 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 BeagleV™ and you will see the startup information as follows：
bootloader version: 210209-4547a8d

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: message, then congratulations, the launch was successful
