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

问题描述

有谁知道一些工具来创建C应用程序调用树，将在微控制器（Cortex-M3的）运行？它可以从源头code（不理想），目标code（prefered液）中产生，或者在运行时（接受）。我看着gprof的，但还是有很多缺失让它在嵌入式系统上运行。

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.

另外一个好处是，该工具还提供了最大堆栈深度。

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

更新：解决方案是preferably免费

Update: solution is preferably free.

推荐答案

要实现这一目标的一个好方法是使用 - 调用图选项将ARM链接器（armlink ）这是RVCT（部分的不的自由）。

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

我从你正在寻找一个基于GCC的解决方案，而这并不是一个评论实现。但它仍然可能会有所帮助。

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.
