ELF文件认为它的小，但它的大！不能生成的.bin和.HEX文件 [英] elf file thinks its small, but its large! can not generate .bin and .hex files

问题描述

我的工作从凯尔的一个项目迁移到GCC。

I am working on migrating a project from Kail to Gcc.

的http：//www.copypaste$c$c.com/73860/
.LD文件的http：//www.copypaste$c$c.com/73856/

我有一个Makefile和platform.ld脚本和一些.c和.h文件。
当我做，一切编译和链接，它看起来不错。

I have a Makefile and a platform.ld script and some .c and .h files. When i make, everything compiles and links and it looks good.

臂无 - EABI尺寸-B输出/ stm32_gps_test.elf

  0       0    2048    2048     800 Output/stm32_gps_test.elf

但是当我检查生成的文件，我看到这一点：

but when i check the generated files i see this:

LS输出/

什么是错的？我试图运行objcopy把创建一个binfile和hexfile但结果总是一样的。

What is wrong? i have tried to run objcopy to create a binfile and hexfile but the result is always the same.

推荐答案

当你拆开它你怎么看？ （objdump的-D）如果在0x20000000具有例如在0x80000000的一个ROM图像和柱塞从objcopy把.bin文件将是在最低0x60000000字节加上在ROM中的图像的大小。英特尔十六进制文件或SREC应的工作，虽然。

When you disassemble it what do you see? (objdump -D) If you have for example a rom image at 0x80000000 and ram at 0x20000000 the .bin file from objcopy will be at a minimum 0x60000000 bytes plus the size of the image in rom. The intel hex file or srec should work though.
