how to build and create opensbi.bin and image files as in Pre-built Bitstreams and Linux/OpenSBI images #282

Open zoro269 opened 2 years ago

https://github.com/litex-hub/linux-on-litex-vexriscv/issues/164#issue-767463348 I have followed the steps but still not working. The purpose I want is to be able to build an openSBI image file like in the instructions above

Hi @zoro269,

here is some code I used recently and that will probably be integrated soon in the repository:

def opensbi_build():
    # Be sure third_party dir is present and switch to it.
    create_third_party_dir()
    os.chdir("third_party")

    # Get OpenSBI.
    if not os.path.exists("opensbi"):
        os.system("git clone https://github.com/litex-hub/opensbi --branch 0.8-linux-on-litex-vexriscv")
    os.chdir("opensbi")

    # Configure / Build OpenSBI.
    os.system("make CROSS_COMPILE=riscv64-unknown-elf- PLATFORM=litex/vexriscv")

    # Copy Linux Images.
    os.system("cp build/platform/litex/vexriscv/firmware/fw_payload.bin ../../images/opensbi.bin")

Please let me know if you still have troubles building with this.

Hi enjoy-digital Can you guide me the running steps and order of running? I still don't quite understand. Many thanks

This should work:

git clone https://github.com/litex-hub/opensbi --branch 0.8-linux-on-litex-vexriscv
cd opensbi
make CROSS_COMPILE=riscv64-unknown-elf- PLATFORM=litex/vexriscv

The binary is then located at build/platform/litex/vexriscv/firmware/fw_payload.bin.

I followed the instructions and got some errors as follows:

This leads to the file opensbi/build/platform/litex/vexriscv/firmware there is no file fw_payload.bin and here is a picture of my firmware image

@zoro269: Can you test with the GCC toolchain provided by python3 litex_setup.py --gcc=riscv?

(https://github.com/enjoy-digital/litex/blob/master/litex_setup.py#L323-L345)

zoro269 commented 2 years ago

@enjoy-digital I have installed and tried the toolchain and still have the error

Thanks guys, I fixed it with the gcc toolchain that was shown and downloaded in the litex_setup.py file. But can you guys explain to me the difference between these two versions of gcc toolchain?

Hi @zoro269,

the OpenSBI build probably require a minimum GCC version to build correctly. We haven't analyzed this so just recommend using the version that has been used successfully.
