关于OMAP-L138_FlashAndBootUtils_2_40的编译

我在linux下编译OMAP-L138_FlashAndBootUtils_2_40，总提示如下错误：

undefined first referenced
symbol in file
--------- ----------------
start

error: unresolved symbols remain
warning: entry-point symbol "start" undefined
warning: no suitable entry-point found; setting to 0
error: errors encountered during linking; "../sft_C6748_SPI_MEM.out" not built

>> Compilation failure
makefile:165: recipe for target '../sft_C6748_SPI_MEM.out' failed
make[2]: [../sft_C6748_SPI_MEM.out] Error 1 (ignored)

我发现C6748相关的编译，都无法生成.o文件，导致后面也无法生成ASI格式的bin，请问我这个问题应该如何解决？

    请问是否有修改过源码？是否按照下面的步骤重新编译的？

    是按照文档设置好了编译器的路径的，改过divece.mak: ,设备定义只留下了OMAP-L138

    # Generic string for device family
    DEVSTRING=OMAP-L138

    # Particular device types of the family
    ARM_DEVICETYPES:=OMAPL138 #AM1808 AM1810 OMAPL138_LCDK
    #DSP_DEVICETYPES:=C6748 #C6748_LCDK
    DEVICETYPES:=$(ARM_DEVICETYPES) $(DSP_DEVICETYPES)

    # Supported flash memory types for booting
    FLASHTYPES:=SPI_MEM #NAND #NOR

    编译时会出现几个不能识别的变量：


    1、 EXTERNAL_RAM_START ./dsp_obj/aisextra.obj ，这个变量很多文件应用，但就是没有找到在哪申明的，所以编译时老是说没有定义。

    2、_PatchDDRConfig  在AISextra/src目录下makefile中出现的 DSP_LNKFLAGS=-z -a -u_PatchDDRConfig -w -x，后将_PatchDDRConfig前的 _ 去掉

     3、shart     应该在start.asm和start_C474x.asm中

    以上三个变量提示过没有定义。

    还提示如下错误：

    /home/zdm/ti_cgt/ti-cgt-c6000_8.2.1/bin/cl6x -z -a -u _PatchDDRConfig -w -x -o=../DSP_AISExtra_OMAP-L138.out DSP_AISExtra.cmd ./dsp_obj/aisextra.obj

    这是在cmd文件里定义的。

    问题解决了吗？我也遇到类似问题。

    您好，这个具体定义应该怎么定义呢？您给的那个链接没找到有关于boot的内容啊
