向UBOOT中移植代码总结

来源：互联网发布：js 数组转对象编辑：程序博客网时间：2024/05/15 12:59

1.首先，将要移植的代码目录（如bootpicsnd）整个拷贝到UBOOT工程中，最好放到对应的board目录下。

2.在bootpicsnd目录里，新建一个Makefile，参考如下：

include $(TOPDIR)/config.mk

LIB := $(obj)libbootpicsnd.a

COBJS = cdjpeg.o jaricom.o jcomapi.o jdapimin.o jdapistd.o jdarith.o jdatasrc.o jdcoefct.o jdcolor.o jddctmgr.o jdhuff.o jdinput.o jdmainct.o jdmarker.o jdmaster.o jdmerge.o jdpostct.o jdsample.o jdtrans.o jerror.o jidctflt.o jidctfst.o jidctint.o jmemmgr.o jmemnobs.o jquant1.o jquant2.o jutils.o wrbmp.o jpeg.o I2CMaster.o cmd_I2C.o bootpic.o bootsnd.o

SRCS := $(COBJS:.o=.c)
OBJS := $(addprefix $(obj),$(COBJS))

all: $(LIB)

$(LIB): $(obj).depend $(OBJS)
$(AR) $(ARFLAGS) $@ $(OBJS)

#########################################################################

# defines $(obj).depend target
include $(SRCTREE)/rules.mk

sinclude $(obj).depend

#########################################################################

注意：特殊颜色部分为对应的C文件，和这些原文生成的.o要ar成的库libbootpicsnd.a

3.在顶层的Makefile里，填加如下一句，使生成的uboot elf文件中，包含进libbootpicsnd.a

LIBS += board/hs3000/bootpicsnd/libbootpicsnd.a

4.make hs3000_config;make

5.此时一般都会报头文件的问题，想办法解决之。

6.编译成功后，会在相应的目录下（bootpicsnd）生成bootpicsnd.a，在u-boot.map中，能看到bootpicsnd.a相关的内容。

7.ok。
