Please remove unnecessary .o files, thanks.

[JayeshRajam]

Done! Please check now.

can you please help to add notification about chmod for image_gen_gnu ? we encounter "../make-image.sh: 29: ./image_gen_gnu: Permission denied" error while following your steps.

[JayeshRajam]

Hey! was the error encountered in the Docker steps. If so, maybe running the docker commands with sudo one by one can resolve this. This is the guide I followed for docker installation on Ubuntu (in order to avoid version conflicts): https://docs.docker.com/engine/install/ubuntu/ I have not faced any such permission error, I also build the application from a different system too. Any image describing the error you can please send so that we can figure it out.

yes, error happen when following command sudo docker run --rm -it -v $PWD:/app:delegated himax-build-gnu /bin/bash -c "cd build-gnu && make -j && sh ../make-image.sh GNU"

and the error message is: /opt/arc_gnu/arc_gnu_ei_prebuilt_minimal_elf32_le_linux_install/bin/../lib/gcc/arc-elf32/10.2.0/../../../../arc-elf32/bin/ld: total time in link: 0.266359 [100%] Built target app.elf GNU Image Gen Tool ../make-image.sh: 29: ./image_gen_gnu: Permission denied

I replaced the make_image.sh file with one from my local computer also tested it. It works. Check now.

clone again and same error here, i think the reason is because image_gen_gnu need +x mode to be executed

[JayeshRajam]

Hi @bigcat-himax, you were correct, when transferred to other PC , permissions Issues are faced. Also you were correct about the +x mode. I ran two commands (going in image_gen_linux) chmod u+x image_gen_gnu chmod u+x sign_tool (came one dir back and ran the sudo docker run --rm -it -v $PWD:/app:delegated himax-build-gnu /bin/bash -c "cd build-gnu && make -j && sh ../make-image.sh GNU" command) and it worked. Thank you for the help.

So, should I add these chmod commands in Readme file or make another commit with updated files(I am not sure whether it'll do it) ?

It would be great if you can commit with updated files, thanks.

[bigcat-himax]

by the way, please copy License file into your project, you can find them in the example template.

[JayeshRajam]

Done! I had to make 2 commits so as to remove and add the upgraded files as modified was not available. Now, I guess everything is done with no errors. Looking forward to merger of pull request.

[bigcat-himax]

seems +x mode to github file makes no effects, still see permission error

can you add chmod commands in Readme file instead? i see following files will need +x permission

• image_gen_gnu
• image_gen
• sign_tool

[JayeshRajam]

@bigcat-himax I updated the readme file. Check
