I am facing error mentioned in the title, after running "sudo python3 5518.armplat_1901.py"

I am using Ubuntu 18.04 on Virtualbox 6.1.
I installed all the dependencies and and cloned "DomainProcessIsolation-AArch64".
(for now, I haven't used "repo init" command. I'll do it later).

After running python script, my configurations are as below:

Can you guide me how to resolve it ?

Hello,

• First, FVP cant be run on VM ( e.g., virtual box, vmware)
• Download .7z file (arm-reference-platforms_OpenEmb.7z) to test FVP on your OS https://m.blog.naver.com/PostView.nhn?blogId=ziun99&logNo=222155628459&navType=tl

Thanks!

Oh. Thanks a lot .
You actually saved my lots of time.

Coming to my original question, the error got resolved automatically.
I tried running the script, 2 or 3 times after the error message, and it ran the script successfully.

But, I would like to inform you about a new problem, I faced.
After running the script, I tried "repo init" command as mentioned in the README file.
And it stopped with below error message:

maunik12@maunik-VB:~/maunik/FVPs$ repo init -u https://git.linaro.org/landing-teams/working/arm/arm-reference-platforms-manifest.git -m fvp-yocto.xml -b refs/tags/BASEFVP-2020.08.06

Hope this "repo init" don't have any relation with VM.
Default python version is 2.7.
It was the same version while running the "sudo python3 5518.armplat_1901.py" script.
Can you guide me here, until I start development on real hardware instead of VM ?

Thanks.

First, I think It doesn't matter if you use Python2 or 3.

Please check,

• Check pip version and upgrade.
• Check run script sudo or nomal, both
• ...

ps., I know FVP setting is very hard, In addition, there are few official documents or versions of the FVP or Foundation model are too varied.
Check both FVP and Foundation models as options.

Thanks!
