1.Get RT-Thread RTOS source code 
?[http://code.google.com/p/rt-thread/downloads/detail?name=rt-thread-0.4.0%20beta1.zip](http://code.google.com/p/rt-thread/downloads/detail?name=rt-thread-0.4.0%20beta1.zip)
2. Install scons build system 
?Make sure you have installed python 2.5.x and scons 1.x or 2.x, belowing is the download URL of the software for windows users: 
1.[http://www.rt-thread.org/download/python-2.5.2.msi](http://www.rt-thread.org/download/python-2.5.2.msi) 
2.[http://www.rt-thread.org/download/scons-2.0.1.win32.exe](http://www.rt-thread.org/download/scons-2.0.1.win32.exe)

3. Install compiler 
?You can choose to GNU GCC or armcc as compiler. 
?If using gcc compiler, CodeSourcery? toolchain is one of the choice. 
?If using armcc, Keil MDK 3.8 IDE is the choice.

Make sure you have installed one of them. 4. Edit "bspmini2440
tconfig.py" to configure devlopement environment 
?if using gcc compiler, set CROSS_TOOL = 'gcc', else CROSS_TOOL = 'armcc' 
?set EXEC_PATH to your toolchains' install path, for example, my EXEC_PATH = E:/Program Files/CodeSourcery/Sourcery G++ Lite/bin

5. Compile RT-Thread RTOS 
?open command line console, suppose you unzip RT-Thread 0.4.0 beta1 under d:
t-thread, and install Python 2.5 in C:Python25:

cd rt-threadspmini2440 
set PATH=C:python25script;%PATH% 
scons 
?rtthread-mini2440.axf and rtthread-mini2440.bin would be created in "bsp/mini2440" direcotry when compiling successfully

6. Run in QEMU/mini2440 emulator 
?make sure rtthread-mini2440.axf have been created in "bsp/mini2440" direcotry 
?unzip SDCARD.zip file which located in "tools" directory to current directory 
?run run-mini2440-sdcard.bat and RT-Thread RTOS would be run

7. Run in mini2440 dev board 
?use supervivi's command "d" to load rt-thread.bin from PC to board's SDRAM, load address should be set to 0x30000000. RT-Thread RTOS would be run when loaded sucessfully.

8.burn rt-thread.bin to dev board's nandflash 
?install uboot on NANDFLASH 
?boot from NANDFLASH 
?using uboot's "loadb command" to load rt-thread.bin to 0x30000000 
?then execute command "nand write 0x30000000 0x100000 0x120000" 
?then execute command "set bootcmd nand read 0x30000000 0x100000 0x120000/;go 0x30000000" 
?then execute command "saveenv" 
?then reset and boot from NANDFLASH, rt-thread would be loaded from NANDFLASH to SDRAM's 
0x30000000 address by uboot and start running from there.
