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？

Shine：

请问是否有修改过源码？是否按照下面的步骤重新编译的？http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138#Compiling

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：

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
