Feel free to take a try, and give us feedback.

Hello, an error was reported during the "make run_qemu" process: qemu system iscv64: unsupported machine type 'nuclei_u'. How can I resolve it? Thank you

You forget to download qemu, and set PATH, see above notes

wget -q https://nucleisys.com/upload/files/toochain/qemu/nuclei_qemu-2023.07.19-linux.zip
unzip nuclei_qemu-2023.07.19-linux.zip
export PATH=$(pwd)/linux_qemu/bin:$PATH

Could you check which qemu-system-riscv64 to see which qemu you are really using? maybe your system has different qemu installed, you need to verify you are using the one downloaded.

Sorry, I previously added 'export PATH=$(pwd)/Linux'_ Qemu/bin: $PATH "has been added to the~/. bashrc file and can now be run. If possible, could you tell me the difference between the two? Thank you

There is another issue, after executing make run qemu, it got stuck in this interface. How can I solve it? Thank you

1. The qemu downloaded from this link is the lastest qemu from Nuclei, still in development, and have some new features, you can check it by qemu-system-riscv64 --version, another one, I suppose you are download it from our website, it is a official release 2022.12.
2. Please remove work directory under nuclei linux sdk, and make sure you are on feature/optee_5.10 branch, and git submodule updated successfully, and no local changes have been made, and then rebuild this sdk. We also post sample git output in this issue.

Thanks

Hello, I just came into contact with the Riscv and tee fields, and I have another question. May I ask if this project uses qemu/spike to simulate the Riscv environment?

Hi @JESSIY225 , thanks for contact with me, here are some brief answer below:

1. This issue demostrated how to execute OpTEE on a RISC-V processor emulated using Nuclei QEMU
2. qemu and spike are both isa simulator, but qemu contains much more features, we can implement a simple virtual SoC in it, and execute software on it like a real SoC.
3. This RISC-V processor emulated in QEMU is Nuclei RISC-V Processor UX900 series, check https://nucleisys.com/product/900smp.php
4. If you have all your source code and preprequites list in this issue installed, you should be able to run it successfully, we have done this in our own PC many times, so please double check your build log, see what error you may miss

If you are looking for help with RISC-V architecture, please check isa manual here, if your research team are interested in commerical risc-v cpu product with TEE feature, you can contact with me, I can introduce our company sales to you.

Thanks
