Hi Alex, Yes, you need to update your dtc. The latest dtc can be gotten from: http://jdl.com/git_repos/ My makefile looks like this (WARNING: it is whitespace damaged, you must replace the eight spaces in the rules with tabs): 8<-------------------------------------------------------------------- # # Make device tree blobs # src = $(wildcard *.dts) out = $(src:.dts=.dtb) asm = $(src:.dts=.dtb) QUIET = #-q RESERVE = -R 4 SIZE = -S 0x3000 all: $(out) %.dtb : %.dts dtc $(QUIET) $(RESERVE) $(SIZE) -b 0 -O dtb -f -o $@ $^ %.asm : %.dts dtc $(QUIET) $(RESERVE) $(SIZE) -b 0 -O asm -f -o $@ $^ 8<-------------------------------------------------------------------- Best regards, gvb _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
