Actually both situation do happen on 1 base revision that I compiled.
Which can be trace back to the example:
I have no idea why this could happen but what I observed are:
sudo -i can enter root
So the image have no right issues that I do encounter at before revisions.
Then Jupyter can access wo any issues but overlay load are fail no matter how
So the current situation is when I change the base design to a simple AXI-RGB only.
And generate the image again
several reboot shows it can load Jupyter note book and overlays can load wo any issues.
So the question here is why the above base design could introduce such Jupyter initial issue and why bit overlay cannot be load in such case.
