[Pacman du34]

Ok I understand.

I am new in the Linux's world, so it's a little bit complicated for
me, for now !

Thank you very much for your attention.

I'll keep searching and looking through what other architectures do,
like you said. And I come back if I need some more help.

Thanks again, your help has been very useful.

Best regards.

That would all be up to your architecture code. I'm afraid I can't
really help with debugging architectural bringup.

I can only recommend that you look through what other architectures do
as part of their boot sequence, and do something along those lines.

Cheers,
Mark.

Ok thank you very much again for your quick answer.

So I'll keep using v1 flag.

At the beginning of the porting, I was using a kernel version which
does not support Device Tree, I only had a C file to initialize the
drivers for my board. And I'm trying to understand how to add the
support of Device Tree to the kernel. Because now I have a dtb file,
but no message appears during the boot, showing that the kernel knows
it must read this file and use the matching device drivers.

I have seen that some manufacturers use "config USE_OF", in the
Kconfig file, to give the option to add device tree support when
compiling the kernel. So I added the same option, but I don't know how
to confirm that the kernel is now using device tree.

Will it appear some messages, during boot, that indicate the kernel is
really using it ?

Thanks again for your attention,

Best regards.

There was a v0 a while back according to ePAPR, but it's obsolete,
incompatible and no-one uses it anymore (dtc doesn't support it as far
as I can tell). The flag is to tell v1 apart from v0.

There is not currently a v2 or later. Perhaps there might be in future,
so it's worth keeping the flag around, but at present there's
effectively only v1.

Cheers,
Mark.

That works, thank you very much,

I take this opportunity to ask another question... As I have to
specify the DTS version, are there other versions, and if yes, what
are their differences ? I mean, if there are other versions, why to
choose the vesion 2 instead of 3 or 1 ?

Thanks again for your very quick answer.

You're missing the DTS version. Try:

/dts-v1/;
/ {
	comaptible = "manufacturer,device";
};

FATAL ERROR: Unable to parse input tree

[Pacman du34]

Hello all,

I am working on a new Linux port to a new architecture and I would like
to add a dts file to describe my system.

So first of all I wrote the following dts test file :

/ {
    compatible = "manufacturer,cpu";
};

I've read that this is the minimum structure required for a device tree
on the wiki.

But when I try compiling it with dtc (the first line is the command
line) I get this error message :

dtc -I dts -O dtb -o my_file.dtb myfile.dts

Error: myfile.dts:1.1-2 syntax error
FATAL ERROR: Unable to parse input tree

I tried both the dtc version of Linux source code (1.2.0-g37c0b6a0) and
dtc version installed with "apt-get install device-tree-compiler" (1.3.0).

I searched on Google but I have not found relevant information for my issue.

I really do not understand what the problem here and I am totally stuck.
Any help will be appreciated.

Thanks a lot in advance.

Best regards.
