调用树嵌入式软件 [英] Call tree for embedded software

问题描述

有没有人知道一些工具来创建一个可以在微控制器（Cortex-M3）上运行的C应用程序的调用树？它可以从源代码（不理想），对象代码（优选解决方案）或运行时（可接受）生成。我已经看过gprof，但是还是很少失去它在嵌入式系统上的工作。

另外一个额外的好处是，该工具也给出最大的堆栈深度。

更新：解决方案最好是免费的。

解决方案

实现这一点的一个好方法是使用作为RVCT（不免费）一部分的ARM链接器（armlink）的 - callgraph 选项。

有关详细信息 - callgraph文档。

我从一个意见中发现您正在寻找基于gcc的解决方案，而不是。但这可能仍然是有用的。

Does anyone know some tools to create a call tree for C application that will run on a microcontroller (Cortex-M3)? It could be generated from source code (not ideal), object code (prefered solution), or at runtime (acceptable). I've looked at gprof, but there's still a lot missing to get it to work on an embedded system.

An added bonus would be that the tool also gives the maximum stack depth.

Update: solution is preferably free.

解决方案

One good way to achieve this is by using the --callgraph option to the ARM linker (armlink) that is part of RVCT (not free).

For more details - callgraph documentation.

I realize from one of the comments that you are looking for a gcc-based solution, which this isn't. But it may still be helpful.
