I follow https://github.com/Nuclei-Software/nuclei-linux-sdk/tree/feature/optee_5.10_wg/optee#optee-%E8%AF%B4%E6%98%8E to build linux SDK with optee_5.10_wg branch, and get the following error after run make SOC=evalsoc CORE=ux900fd BOOT_MODE=sd freeloader command: 

 GEN     /mnt/fileroot2/sichun.qin/code/github/nuclei-linux-sdk/work/evalsoc/optee/optee_os/core/tee.bin

Hello, could you check your submodule is updated and no changes are made, we forget to push some code to this repo, now all are pushed, you can try

git fetch
git submodule init
git submodule update

Thanks, but still not work. I am wondering the error is related to pyelftools version. I am using 0.23, and I see the risc-v support is added to pyelftools since Feb. 2023. I have no privilege to upgrade my dev machine python library, and I will try to find another machine to verify the issue.

0.27 works well. I think >=0.27 would work as well.

Thanks @sichunqin for your reporting.

According to optee requirement, these tools are required, https://optee.readthedocs.io/en/latest/building/prerequisites.html

pyelftools is a requirement, you can install it via pip3 tools, see https://pypi.org/project/pyelftools/

I will close this issue, since you have fixed it.

This is EM_RISCV as described here https://github.com/eliben/pyelftools/blob/9ffa0b515b9a24495e81b36fcc698c2376af27de/elftools/elf/enums.py#L257

Can't find elftools module. Probably it is not installed on your system.
You can install this module with

$ apt install python3-pyelftools

if you are using Ubuntu. Or try to search for "pyelftools" or "elftools" in
your package manager if you are using some other distribution.
