Hi Robert,

I don’t understand what you mean by the /bb.org-overlays/. Am I supposed to place my version of the example files into this directory?

yes "copy" your version of the file into the same folder the original
example lived, then moved down two dir and run "make"..

https://github.com/beagleboard/bb.org-overlays

./bb.org-overlays/src/arm/(location of dts's)
./bb.org-overlays/ (where you run make from)...

Regards,

I've been editing the file in Notepad and Visual Studio then copying them
over to a nano file saved as *.dts*. I believe the reason its giving me an

  I'd definitely still be concerned about line endings on those files. I
know the BASH shell will choke if given a file with a <cr><lf> line ending
(I've used SciTE as a general editor on Windows, and have to remember to
set the option for <lf> line endings, and maybe even run "convert line
endings" option before saving).

error on the "#include" statements is because they need to be pre-compiled

  Presuming #include directives function as they do in C -- they should
copy in the /source/ file during compilation.

  Based on subsequent posts, they require the C PreProcessor to perform
that action...

UPDATE 2:

I was able to get my version of the overlay to compile and I believe it works, although it is mostly original code that I don’t need and afraid to remove. Unfortunately, I cannot test it on my display because the connector I had broke :(.

Is there anyway I can list the pin functions of each pin to ensure that all 24 bits are working? I think there is a utility that allow this, however, I don’t believe I have it installed. Is there perhaps an easier way to do this without downloading and installing things?

Hi guys,

Going back to last weeks update, are there any utilities that can display the current pin configuration without installing anything?

Hi Robert,

Is there a simple overlay for enabling all 24 bits of LCD_DATA without any backlight support that is on Github?
