BBAI LCD cape and BBBl cape compatibility

Looking for LCD cape compatibility info for the BBAI. https://beagleboard.org/ai web page lists

Board Feature Highlights- BeagleBone Black mechanical and header compatibility

If so, does that mean the BBAI supports or will support BBBl LCD capes such as the 5" and 7" 4D modules?

I received a couple 4D LCD capes that I hope will work for my BBAIs. Will they?

As far as I know, the overlays haven’t been updated. @lorforlinux @RobertCNelson know any better?

The cape compatibility layer should enable a common overlay to be created and all the right pins should be in the right place, but I’m not aware of anyone having done the work.

What does “the work” encompass?

Who does this “work”?

I’m very new here, I’ve come from a world where all my projects have had how-to instructions and been served up on a plate.

I purchased multiple BBAI thinking everything worked and then discover GPIO doesn’t work, via the guy who wrote the os and designed the board (am I right?).

c,c++ or something else?

I don’t understand what your sentence is supposed to mean, sorry.

It has been a while, what are you coding with c/c++ or something else?

I’m not coding at all yet. Just looking to get a nice Debian installed and use these lcd.

Would you please post a link to the exact LCD you are using. And, what board are you using?

I have 4x of these 4D Systems 70T LCD Capes:

And I have 3x of these Beaglebone AI SBC:

I’m sorry of I am confusing you. I understand that your intentions are to help.
In this project, I have only plugged in the BBAI once to see what was going on, read a little online and found myself overwhelmed.
I came here thinking that this is the place for best help, tutorials, etc. but I feel like I am asking for more than what is available.
At the very least I would like to use one of these as a Debian machine. I would like to learn and explore the AI part and hopefully eventually do the projects I wrote about in that other thread.
If there is another place to also read/learn/post, please let me know.

Thank you and have a good day.

The situation is not too good.

They are not supportting it, last working version was on kernel 3.x.

Myself, I would send them back.
If you paid a developer to get that up and running your cost would be a guess in excess of $10-15k USD minimum. Since they are selling the product and do not have anything even remotely current means they did not get it up and running or it would have a “blinky” demo. A working “triangle” would make that an extremely popular item.

Something you need to do when dealing with anything that involves big tech and the internet is to do your due diligence first. If they cannot provide the end user with a crude “triangle” or other measure to prove it actually does work, run in the opposite direction. The deeper you go into this you will discover how many of the tech companies are playing games.

Another red flag is if they are selling services/custom work. It means the product offered is just to lure you in. They intentionally withhold information and make the docs extremely terse then skip over the important details. If it smells like an infomercial, it is.
