Hi,
I am using QCVS to make some changes in the device tree file. However, I do not know which file I should open. I find the next path:
./build_t2080rdb_release/tmp/work/t2080rdb-fsl-linux/linux-qoriq/3.12-r0/packages-split/kernel-dev/usr/src/kernel/arch/powerpc/boot/dts/t2080rdb.dts
./build_t2080rdb_release/tmp/work/t2080rdb-fsl-linux/linux-qoriq/3.12-r0/image/usr/src/kernel/arch/powerpc/boot/dts/t2080rdb.dts
./build_t2080rdb_release/tmp/work/t2080rdb-fsl-linux/linux-qoriq/3.12-r0/git/arch/powerpc/boot/dts/t2080rdb.dts
./build_t2080rdb_release/tmp/work/t2080rdb-fsl-linux/linux-qoriq/3.12-r0/package/usr/src/kernel/arch/powerpc/boot/dts/t2080rdb.dts
./build_t2080rdb_release/tmp/work/t2080rdb-fsl-linux/linux-qoriq/3.12-r0/sysroot-destdir/usr/src/kernel/arch/powerpc/boot/dts/t2080rdb.dts
./build_t2080rdb_release/tmp/sysroots/t2080rdb/usr/src/kernel/arch/powerpc/boot/dts/t2080rdb.dts
Once I select one, what I should do to perform the change?

Solved! Go to Solution.
You should alter
../tmp/work/t2080rdb-fsl-linux/linux-qoriq/3.12-r0/git/arch/powerpc/boot/dts/t2080rdb.dts
After you are done with your modifications, rebuild the kernel with
'bitbake linux-qoriq' or rebuild just DTB by invoking dtc directly,
see man dtc for details.
Note that if you perform 'bitbalke -c clean' or 'bitbake -c cleansstate' your changes
will be lost. To avoid this, save your DTB to a separate file and
add it to KERNEL_DEVICETREE in /sources/meta-freescale/conf/machine/<your_board>.conf

In QCVS, create a project for your target and select Device Tree Editor as component. You can import a .dts file using Wizard. After customization, you have to build the .dts file using dtc for the target.
