RT thread learning notes (V) -- edit, download and debug programs

Software environment ：Win7,Keil MDK 4.72a, IAR EWARM 7.2, GCC 4.2,Python 2.7 ,SCons 2.3.2

Hardware environment ：Armfly STM32F103ZE-EK v3.0 Development board

 

Continued , When the program is compiled , You can connect JLINK Or other debugging tools to download and debug .

【1】 Development environment settings

(1) Modification use scons --taget=mdk4 -s Command generated keilMDK engineering Options->Output Page Brows information There is no selection problem by default
Use Notepad++ Open... Under the development branch directory template.uvproj file , Locate the 52 Near the line , Can make <BrowseInfromation> label , Repair as follows ：
<DebugInformation>1</DebugInformation>
<BrowseInformation>1</BrowseInformation>
<ListingPath>.\build\</ListingPath>
Save and close the file after modification .

(2) Two points need to be explained （ in the light of MDK4 development environment ）：

First of all , If you change the path of the source file , It needs to be reused scons --tartget=mdk4 -s Generate once , To update the file path .

second , Need to be in MDK Reset the location of the object code in the environment , Here's the picture

After setting up , Click on KeilMDK IDE Interface Download Button , Start downloading code , The results are as follows .

Press... On the development board Reset Button , You can see the following information on the serial port terminal ：

If you can't see the above information , Please look at the terminal COM Is the mouth connected .

If everything is right , Press down Debug Button to enter the debugging interface .

【2】 Solve the problem of using Scons Compile and use KeilMDK The compilation output directory is inconsistent

It was found during the test that , Use at the command terminal Scons Compile time , Intermediate files are output to Build Catalog , Here's the picture

rtthread-stm32.bin and rtthread-stm32.axf The file is output to the root directory of the created Branch , But in KeilMDK When downloading in the environment ,KeilMDK The default location output directory is Build, This will lead to the use of KeilMDK During compilation, the intermediate file will be output to the root directory of the branch , It looks messy . No solution was found online , After some research on the compiled script , A solution has been found .

open rt-rthread-1.2.2/tools/building.py, Locate the 196 That's ok , You can see the following code ：

# board build script
    objs = SConscript('SConscript', variant_dir='build', duplicate=0)
    Repository(Rtt_Root)
    # include kernel

Compiled build The catalogue comes from here , So you only need to Sconstruct File first 13 Change the line to the following code ：

TARGET = 'build/rtthread-stm32.' + rtconfig.TARGET_EXT

The red words on the top line are only added. Note that the slash can linux The style is consistent , It's not a backslash , Then save , use scons -c Clear previous compilation results , Rerun scons compile , give the result as follows ：

Browse again in the manager , Here's the picture .

rtthread-stm32.axf The file was generated in build Under the catalogue , This solves the above problems .

【3】, Light up the LED The lamp

On the development board LED1 and LED2 The hardware interface corresponds to PF6 and PF7 Pin , open stm32f103ze-ek/diriver/led.c, Locate the 29 That's ok , Revised as follows ：

#else
#define led1_rcc                    RCC_APB2Periph_GPIOF
#define led1_gpio                   GPIOF
#define led1_pin                    (GPIO_Pin_6)
#define led2_rcc                    RCC_APB2Periph_GPIOF
#define led2_gpio                   GPIOF
#define led2_pin                    (GPIO_Pin_7)
#endif // led define #ifdef STM32_SIMULATOR

Then save , use scons Command compilation , Download to the development board , Then press the reset button ,OK,LED1 Flashing ,LED2 Changliang .

【4】rtconfig.h About... In the configuration file FINSH_USING_MSH Compilation options problem

By default ,FINSH_USING_MSH The compilation option is not turned on , When you want to use msh Command line style , You need to open this option for reference RT-Thread Programming Guide .

(1) open rtconfig.h, Locate the 80 Near the line , Code Revised as follows ：

/* SECTION: finsh, a C-Express shell */
#define RT_USING_FINSH
/*Support MSH style*/
#define FINSH_USING_MSH
/*Support MSH style only,not support C-Express*/
//#define FINSH_USING_MSH_ONLY
/*Support work dictionary,when use MSH style shell,suggest open this option*/
#define DFS_USING_WORKDIR
/*Support historical retrospect*/
#define FINSH_USING_HISTORY
/* Using symbol table */
#define FINSH_USING_SYMTAB
#define FINSH_USING_DESCRIPTION

(2) take msh Relevant codes are added to the project

msh The function code is msh.c and msh_cmd.c In file , file components/finsh Under the table of contents , Add it to the project , Here's the picture .

(3) Repair the Sconscript Script , Make sure that the componets/finsh Under the table of contents Sconscript Of documents 24 Line adds the following code ：

msh_src = Split('''
msh_cmd.c
msh.c
''')

The above code has been added by default , In general, there is no need to modify .

Then save the compilation , Download to the development board ,

finsh />list()
--Function List:
led -- set led[0 - 1] on[1] or off[0].
fs_test -- file system R/W test. e.g: fs_test(3)
list_mem -- list memory usage information
mkfs -- make a file system
df -- get disk free
ls -- list directory contents
rm -- remove files or directories
cat -- print file
copy -- copy file or dir
mkdir -- create a directory
cd -- change current working directory

0, 0x00000000
finsh />msh()
0, 0x00000000
msh />

You can see that the command prompt has changed to msh 了
