compiling a dts file

[evilwulfie]

So i need to create a dtb file for some custom hardware.
I made one 2 years ago that compiled correctly
on the latest IOT image it does not compile.
So i figure, hey maybe something has changed
so i pull the /opt/source/bb.org-overlays/src/arm/BB-I2C1-00A0.dts file
to a temp directory and try to compile it
Funny i get the same error and i get no compile.

Error: BB-I2C1-00A0.dts:13.1-9 syntax error
FATAL ERROR: Unable to parse input tree


just wondering whats changed.

apt says i am at the latest dts compiler

anybody try to compile anything recently ?

I do hardware. Software was something i did in the 80s z80 asm code and
c coding on a univac ( yeah i know )

If i run your command as root in my current directory

root@beaglebone:/home/debian# make src/arm/BB-I2C1-00A0.dtb
make: *** No rule to make target 'src/arm/BB-I2C1-00A0.dtb'.  Stop.


Been using linux since the 90s

2 years ago i could just invoke the dts compiler

dtc -O dtb -o BB-I2C1-00A0.dtb -b 0 BB-I2C1-00A0.dts

in whatever directory i was in normally someplace safe where i can play
without fear of destroying something important

now things have changed and its tough to see whats changed
all examples everywhere also say i can invoke the compiler in a temp
directory.

thanks Robert for your assistance.

git clone https://github.com/beagleboard/bb.org-overlays
cd ./bb.org-overlays/
make src/arm/BB-I2C1-00A0.dtb

There's "include" files in the *.dts now... dtc doesn't handle includes's..

ah forgot the "o" at the end:

make src/arm/BB-I2C1-00A0.dtbo
DTC src/arm/BB-I2C1-00A0.dtbo
