Since the error didn’t disappear, I decided to consistently execute the commands that kwagyeman had written to me and check

cd openmv
source tools/ci.sh && ci_update_submodules
sudo apt-get update

After that, I decided to check the firmware build again.

make -j$(nproc) TARGET=OPENMV_N6

The errors disappeared after running these commands:

cd openmv

sudo apt-get update

No need, like I said the commands I gave you are all you need, also I managed to reproduce the issue and will fix it.

Great !!! I’ll check it out in the morning, but it’s already late at night, and I’m going to bed. Thank you so much!

Hi iabdalkader, kwagyeman !

You guys are magicians !!!

After the fixes made by iabdalkader, everything works perfectly, and there are no unnecessary warning or error messages! Today, I installed Ubuntu from 0 again this morning, and set everything up. I built the firmware 5 times (by first deleting all files from the Build folder - the project always builds perfectly and 7 files are created in the folder.

Thank you again for solving the problem. Now, anyone who doesn’t already have a configured Linux system can quickly create their own firmware from source code using WSL by running a few commands in sequence. It’s amazing!
