OP-TEE build does not continue after OpenSBI

[swidi]

Hello,

I am currently working on a research project that involves OP-TEE on RISC-V. Your project would serve as a great starting point, however I cannot get it to run.

I have used your docker image: sudo docker run -it nucleisoftware/linuxsdk:optee

And then followed the advice here: https://hub.docker.com/r/nucleisoftware/linuxsdk

# cd linux sdk workspace
cd nuclei-linux-sdk
# see commit log of last one
git log -1
# fetch latest commits if needs
git fetch
# pull latest changes if needs
git pull 
# do submodule updates 
git submodule update
# build project just follow https://github.com/Nuclei-Software/nuclei-linux-sdk#show-help in each branch
# run qemu for SOC=evalsoc CORE=ux900fd
make run_qemu

Unfortunately, the boot process never continues after OpenSBI:

Since I believe I have followed every step as indicated, could it be that the docker image is no longer compatible with the latest commits? Or any other idea that could point me in the right direction? Thanks!

Hi @swidi , see #8 we have mentioned which branch has enabled docker support. please follow this https://github.com/Nuclei-Software/nuclei-linux-sdk/blob/feature/optee_5.10/optee/README_en.md to run it.

• Make sure you are on the right branch: feature/optee_5.10 and have the latest commit and submodule update even you are in the docker environment
• Make sure you are using a expected qemu 8.0 2024.02, downloaded from https://nucleisys.com/download.php
• For run on evalsoc, you need to pass make SOC=evalsoc CORE=ux900fd run_qemu not make run_qemu

There is also a quick guide here #13 attached with run log

[fanghuaqi]

For your case, I think this is wrong

# build project just follow https://github.com/Nuclei-Software/nuclei-linux-sdk#show-help in each branch
# run qemu for SOC=evalsoc CORE=ux900fd
make run_qemu # wrong
make SOC=evalsoc CORE=ux900fd run_qemu # correct

[fanghuaqi]

Other people already repeat it, see #16

[swidi]

Wonderful. make SOC=evalsoc CORE=ux900fd run_qemu # correct was indeed the solution. Thank you!
