Hi
I am getting DTC when compiling dts file with CONFIG_OF_CONTROL. The message says that it cannot find skeleton.dtsi though its placed in the same directory as the dts file. I notice that if i remove this line from the dts Makefile, the error disappears
$(DT_BIN): $(TOPDIR)/board/$(VENDOR)/dts/$(DEVICE_TREE).dts
- cat $< | $(CPP) -P $(DTS_CPPFLAGS) - >$@.tmp
- $(DTC) -R 4 -p 0x1000 -O dtb -o ${DT_BIN} $@.tmp
- rm $@.tmp
- $(DTC) -R 4 -p 0x1000 -O dtb -o ${DT_BIN} $<
Has anyone faced this issue?
Not really, although I haven't used a skeleton file on mainline. One thing to check is that you have a .dtsi extension.
The lines above are running the .dts file through the C proprocessor to create a tmp file, which is then compiled. It is only really used to get the name of the SOC's device tree include file - see the definition of DTS_CPPFLAGS.
The tmp file should be in the same directory - check the file it produces and see what is wrong with it. The reason for using a tmp file is that people can check the resulting post-processed input to dtc. I wonder if the # signs in the file are confusing the preprocessor (at the time I wondered why they didn't). We should perhaps add sed into the mix :-(
Thanks Hanumant
