Before compiling EDK2 and EDK2-Platform code ensure you perform the following steps:
Create a project folder name “vf2_uefi”
> mkdir vf2_uefi
Setup environment
export GCC5_RISCV64_PREFIX= <RISCV_tool_chain>
export PACKAGES_PATH=<project_path>/vf2_uefi/edk2:<project_path>/vf2_uefi/edk2-platforms
export EDK_TOOLS_PATH=<project_path>/vf2_uefi/riscv-edk2/BaseTools
_ - version 10.0.2_
Download U-Boot SPL, Linux, and SD Card images from here.
Refer here documentation for detail instruction to generate linux.iso
Refer here documentation for detail instruction to generate u-boot-spl.bin.normal.out
2. Clone Starfive VisionFive2 EDK2 and EDK2-Platform code
Perform the following steps to download the codes:
Git clones the code
> cd <project_path>/vf2_uefi > git clone https://github.com/starfive-tech/edk2 > git clone https://github.com/starfive-tech/edk2-platforms
Checkout Starfive VisionFive2 EDK2 tag
> cd edk2 > git submodule update --init > cd ..
Checkout Starfive VisionFive2 EDK2-Platform tag
> cd edk2-platforms > git submodule update --init > cd ..
Perform the following the clean-up and build the code:
Setup and clean the project
> cd edk2
> source ./edksetup.sh
> make -C ./BaseTools clean
> make -C ./BaseTools
> make -C ./BaseTools/Source/C
> source ./edksetup.sh BaseTools
> cd ..
Build UEFI image
> build -a RISCV64 -t GCC5 -p <project_path>/vf2_uefi/edk2-platforms/Platform/StarFive/JH7110SeriesPkg/JH7110Board/JH7110.dsc
Build image is located in ../Build/JH7110/DEBUG_GCC5/FV/JH7110.fd

Connect the jumper wire between the USB-to-Serial converter and the Debug pins of VisionFive 2 40-pin GPIO header. The following figure is an example:
Note: If booting from eMMC, hold the reset button for more than 3 seconds to reset the board.
List all and read mapped partitions in SD Card, eMMC and QSPI Flash
> map -r
> FS0:
> ls
Result:
Linux auto-boot can be enabled by creating a startup.nsh file based on the guide here
Select a device that contains the Linux EFI image in UEFI Shell:
> FS1: > ls
Note: FS1 is just an example. You may select other devices FS* that contains the image as well.
Result:
Load initramfs
> initrd initramfs.cpio
Load and run the Linux EFI image
> linux-riscv64.efi console=tty1 console=ttyS0,115200 debug rootwait earlycon=sbi
Verify that Linux is booting from UEFI
> root
> ls -l /sys/firmware/efi
Result:
