Yes I only use the "include" for a test on GPIO,
how can I use one of the overlay and modify it ? thanks

Additionally. This is an error that one typically gets, when trying to
compile one of those overlays without compiling it from the bb-overlay
git project. e.g. downloading one file, and trying ot compile it
manually through dtc. Instead of putting your source file into the
src/arm directory, and moving into the git root directory and issuing
"make". Two ways to go about that, but we can get to that later.
So, knowing what command you used EXACTLY what command when you
attempted to build your file would be necessary.

Without the source, no one will be able to give you a correct
answer. That is, the source file EXACTLY how it is when you got
that error.

Hello everyone,
I have question regarding compiling overlay for cape,
I got the example from :
https://github.com/beagleboard/bb.org-overlays/tree/master/src/arm
<https://github.com/beagleboard/bb.org-overlays/tree/master/src/arm>
Some information that I can collect,
I tried to compile with on these lines :
|
#include<dt-bindings/board/am335x-bbw-bbb-base.h>
#include<dt-bindings/gpio/gpio.h>
#include<dt-bindings/pinctrl/am33xx.h>

the error :

Does anyone know how to fix it ? or experience the same thing ?
Thanks
