We do this in two ways. First, # we copy bootblock.elf to bootblock.raw.elf and allow the %.bin: %.elf # template rule to turn it into bootblock.raw.bin. This makes sure whatever # processing is supposed to happen to turn an .elf into a .bin happens. # # Second, we add our own rule for creating bootblock.bin from # bootblock.raw.bin which displaces the template rule. When other rules that # package up the image pull in bootblock.bin, it will be this wrapped version # instead of the raw bootblock. $(objcbfs)/bootblock.raw.elf: $(objcbfs)/bootblock.elf cp $< $@ $(obj)/generated/bct.bin: $(obj)/generated/bct.cfg @printf " CBOOTIMAGE $(subst $(obj)/,,$(@))\n" $(CBOOTIMAGE) -gbct --soc tegra132 $< $@ BCT_BIN = $(obj)/generated/bct.bin BCT_WRAPPER = $(obj)/generated/bct.wrapper $(objcbfs)/bootblock.bin: $(CBOOTIMAGE) $(objcbfs)/bootblock.raw.bin $(BCT_BIN) echo "Version = 1;" > $(BCT_WRAPPER) echo "Redundancy = 1;" >> $(BCT_WRAPPER) echo "Bctfile = $(BCT_BIN);" >> $(BCT_WRAPPER) echo "BootLoader = $<,$(CONFIG_BOOTBLOCK_BASE),$(CONFIG_BOOTBLOCK_BASE),Complete;" >> $(BCT_WRAPPER) @printf " CBOOTIMAGE $(subst $(obj)/,,$(@))\n" $(CBOOTIMAGE) $(BCT_WRAPPER) $@
