standalone dtc compiler build from git://git.jdl.com/software/dtc.git gives error

standalone dtc compiler build from git://git.jdl.com/software/dtc.git gives error

[Karicheri, Muralidharan]

Hi, Jon Lolieger,

I have tried using the standalone dtc compiler at git://git.jdl.com/software/dtc.git to compile my dts file and got the following error:-

a0868495@ares-ubuntu:~/dtc$ dtc -I dts -O dtb tci6614-evm.dts
DTC: dts->dtb  on file "tci6614-evm.dts"
tci6614-evm.dts:4 syntax error

The dtc in the linux tree (Linux version 3.2) is able to compile the dts file and I am able to boot kernel using the dtb. I am using v1.3.0 tag of the dtc git repo. Comparing the files with that under scripts/dtc in the kernel tree, I find they are different. Why is the dtc not able to compile the dts file? How is the dtc tree synced with the Linux kernel tree? As a user, how do I know what version of dtc I need to use for a given kernel release? Any help here?

I think the only way to answer that is going to be to post your .dts
file, or at least the first 4 or 5 lines of it.

Stephen,

Thanks for responding.

Here it is 

/dts-v1/;
/include/ "skeleton.dtsi"

/ {
        model = "Texas Instruments TCI6614 EVM";
        compatible = "ti,tci6614-evm";
        #address-cells = <1>;
        #size-cells = <1>;

And "skeleton.dtsi" has 

/*
 * Skeleton device tree; the bare minimum needed to boot; just include and
 * add a compatible value.  The bootloader will typically populate the memory
 * node.
 */

/ {
        #address-cells = <1>;
        #size-cells = <1>;
        chosen { };
        aliases { };
        memory { device_type = "memory"; reg = <0 0>; };
};

BTW, the dtc compiler in the Linux kernel tree runs fine. Also I get the same error when I run the
dtc against other existing dts files in the Linux 3.2 kernel tree. Any clue?

Thanks

Murali

That's odd. I just tried both v1.3.0 and master dtc, and could compile
your example just fine. I also compiled
arch/arm/boot/dts/tegra-cardhu.dts from the kernel (next-20120411). Both
worked fine.

Note that I get the error you're seeing if I run Ubuntu's packaged dtc,
which is 1.1.0.dfsg-1build1 on my system. Are you sure you're running
the dtc binary you think you are?

You are right. I never realized that I had a host version of dtc. The problem doesn't happen when I used the git version and I could boot up Linux using the DTB. Now I see the same error when run the command on an ARM
Target machine. I have cross compiled the dtc (using oe (actually Arago)). Not sure if anyone tried this on an ARM target.

The problem is with the oe build. I had done cross compiling outside oe and it seems to work fine. Anyways thanks for your help.
