抱歉，好久没来看过了。
这些年在一家芯片公司工作，环境一直是linux，包括自己的机器和公司服务器，所以几乎不会用到windows，除了打实况 :P

关于stm32的开发，详细的方法可以参考我们的一个开源项目:
https://github.com/LeafGrass/ousia

这个项目里采用 linux host 作为开发环境，有完整的 build system，可以方便地添加/删减模块。
实现的是一个极其简化的操作系统，有最笨的调度和最简单的内存“管理”，最初就在stm32上进行开发成型的。
整个系统连上USB就可以玩了，类似arduino，不需要其它调试设备，只有第一次使用的时候需要烧写一遍bootloader。因此开发也变得非常方便。
相信对于初级阶段的学习非常合适。

有需要的朋友可以随便拿去用，pitolan大大曾教我们饮水思源，非常乐意帮助后来的同学，有问可以直接邮件联系我：

这里把 README 内容贴出来：

Ousia
=======================
COPYRIGHT (C) LEAFGRASS
Introduction
------------
"Ousia" is picked from Greek.
Mainly intend to represent the essence of Real-Time Theory.
Developed following K-I-S-S principle.
Source Tree Architecture
------------------------
* core/
Ousia core routines.
* doc/
Complete documentation of Ousia.
* driver/
Different kinds of device drivers based on Ousia.
They are all configurable.
* framework/
Framework based on Ousia. Such as shell, vfs, etc.
They are scalable and configurable, either.
* include/
Header files of main routines of Ousia.
* platform/
Chip and board specific code, e.g. low-level library.
Ousia porting code are also placed here.
* project/
Project source code. Include several sample project instances.
* script/
Useful scripts used while Ousia developing.
* support/
Basic supporting stuffs for Ousia developing and building.
Useful template files are placed here, such as porting code template.
How to Start for Fresh New Environment
--------------------------------------
- Install toolchain
- Make
For a general purpose, these steps are enough, but there are some more
steps needs to do for each platform.
As for stm32 on linux host, we use dfu/serial/jtag to upload firmware,
setup like below:
- Install Codesourcery toolchain. (e.g. arm-2011.03-42-arm-none-eabi)
- Install dfu-util/pyserial/openocd (it's up to your preference).
Ps: In fedora or ubuntu, yum/apt-get install them is ok.
- Resolve usb or serial access problems.
(e.g. copy ousia/support/dfu/45-maple.rules to /etc/udev/rules.d/)
- Install minicom for console print if you want to debug with uart.
Ps: Default port is /dev/ttyACMx
- Do 'make' and 'make install'.
Create User Project Steps
-------------------------
- Create a directory named PROJECT_NAME in folder "project".
- Add user source code.
- Create a file rules.mk to specify source code related rules for makefile.
- Update TARGET_PLATFORM and PROJECT_NAME in main Makefile, then make.
Ps: Refer to existing projects for further detailed information.
Core Developing Steps
---------------------
- Choose or create a branch of yourself to work on.
- Update source code, include those version related strings.
- Modify related Makefiles and configuration files.
- Build then do some testing on this branch.
- Commit it.
- Tag a new one if a new version is commited.
- Push this branch to remote repo.
- If this is a release version, update Ousia Release Notes.
Porting Steps
-------------
- Create a directory named PLATFORM_NAME in folder "platform", then enter it.
- Create three files: rules.mk config.mk target.mk.
@rules.mk: makefile source code related rules
@config.mk: parameters or flags for toolchains and environment
@target.mk: rules for building target
- Create a directory named "port" there then create three files in it.
@ousia_cfg.h: os scalability related configurations
@ousia_port.h: header of porting code
@ousia_port.c: implentation of porting
- Create other porting related stuffs, such as linker scripts, if necessary.
- Update TARGET_PLATFORM and PROJECT_NAME in main Makefile, then make.
Ps: If modified porting related code, should not edit directly in "core/port",
do that in specific platform directory instead, e.g. "platform/stm32/port".
Makefile will copy them into "core/port" automatically depend on specific cpu
types.
Build A Different Platform
--------------------------
Only modify the header TODO in root Makefile
- Assign specific TARGET_PLATFORM and PROJECT_NAME
Download Code to Target Chip
----------------------------
- Modify related User Customization Items in Makefile in source tree.
For stm32, you need to decide which MEMORY_TARGET to use:
jtag, flash, or ram.
- Do proper operation on hardware. (i.e. change boot jumper or reset or sth.)
- Then type 'make install' and it will do everything for you.
Ps: For stm32, there may be a bootloader, 'make bootloader' will download
bootloader code to chip via serial. And for simulation on x86, no code
downloading procedure is needed. See Makefile for detailed information.
