Gdb 如何从uImage（arm）中提取内核符号？

我想从u-boot映像中提取内核符号

最终目标是使用gdb

---

内核是用

CONFIG\u DEBUG\u INFO=y

编译的，gcc使用-g选项（我选中）

在

制作uImage

之后，我：

# file arch/arm/boot/*
arch/arm/boot/bootp:           directory
arch/arm/boot/compressed:      directory
arch/arm/boot/Image:           data
arch/arm/boot/install.sh:      POSIX shell script text executable
arch/arm/boot/Makefile:        ASCII English text
arch/arm/boot/uImage:          u-boot legacy uImage, Linux-3.0.6, Linux/ARM, OS Kernel Image (Not compressed), 3044476 bytes, Thu Mar 22 18:13:40 2012, Load Address: 0x00008000, Entry Point: 0x00008000, Header CRC: 0xF689B805, Data CRC: 0x6BFE76DF
arch/arm/boot/zImage:          data

gdb无法直接加载uImage

---

我试过这个剧本

---

kernel.img不可由gdb加载Do

makevmlinux

。我相信GDB可以读懂这一点，但自从我尝试以来，这是一段很长的时间，而且有很多内核版本

---

编辑：哦，我应该说，vmlinux和uImage应该是相同的，但包装不同。如果不是这样的话，那么这将不起作用。

我知道由于gdbserver出现了一个新问题，但是内核符号已正确加载，谢谢。
