[004] [stm32] MDK project configuration and commissioning

This paper is about Baiwen & Weidong mountain 【 IOT smart home training camp 】 Course notes

1 Engineering configuration

1.1 Device

1.2 Target

Without using software simulation, you can ignore Xtal Parameters .

MrcroLIB Yes C Library has been optimized , quite a lot C Library functions cannot be used directly , The following code can be added without using the micro library , Normal use printf and scanf Redirect to serial port and other output devices ：

#pragma import(__use_no_semihosting)
struct __FILE
{
    
	int a;
};
FILE __stdout;
FILE __stdin;

void _sys_exit(int x)
{
    
	
}

1.3 Output

Don't check Browse Information unable F12 Jump .

1.4 ListIng

• .LST：Listing file generated by the C Compiler or Assembler. C And the list file generated by the assembly compiler .
• .I: C Preprocessor Output File. Preprocessed files .
• .map： Store image files , More important , You can analyze the details of the generated code , Such as code size 、 Memory address occupied by variables, etc .

1.5 User

stay “After Build/Rebuild” add to fromelf --bin -o "[email protected]" "#L", Check... At the same time “Run #1”, Indicates that after compilation , perform fromelf Command to generate bin file .

1.6 C/C++

Use cubemx Generate MDK engineering , You do not need to add a file path .

1.7 Asm

Asm The interface is generally configured with assembly code , Not commonly used .

1.8 Linker

• Use Memory Layout from Target Dialog： Use the distributed file load dialog Target page
• Make RW Sections Position Independent： send RW Segment independence （–rwpi）
• Make RO Sections Position Independent： send RO Segment independence （–ropi）
• Don't Search Standard Libraries： Disable scanning of the default compiler runtime library （–noscanlib）
• Report 'might fail' Conditions as Errors： The reported condition may cause a failed error , Not a warning （–strict）
• xx BASE：X/O、R/O、R/W Base address （–xo_base=address）
• disable Warnings: Police warning （–diag_suppress）

1.9 Debug

• Load Application at Startup： Load application at startup .
  Run to main()： When entering debug mode ,main(), That is, skip assembly code , Jump directly to main Function start simulation .
• Reset debug session settings Restore Debug Session Settings： If you check , Click on it. “ Reset ” Will return to the previous state . Include ： The breakpoint Breakpoints、 window Watch Windows、 Performance Analyzer Performance Analyzer、 Memory window Memory Window、 hold-all Toolbox、 System Finder System Viewer etc. .
• Dialog DLL - Parameter： Conversation box DLL Documents and parameters ;CPU/Driver DLL - Parameter：CPU Driver files and parameters .
  Dialog DLL Respectively ： DARMSTM.DLL and TARMSTM.DLL Parameter Are all ：pSTM32F103RC(p+ Specific chip signals ), Used to set the software and hardware simulation that supports the corresponding chip （ That is, it can be done through Peripherals Select the dialog box of corresponding peripherals and observe the simulation results ）.
• Manage Component Viewer Description Files： Manage component description files （ Generally do not use ）

Hardware simulation download configuration ：

2 Simulation debugging

2.1 General debugging window

2.2 Observation window

Look at the value of the variable ：

Default 16 Base display , Modifiable .

View kernel and peripheral register values ：

If you look at GPIOA register ：

Check the kernel peripheral registers NCIC：

• E： Can make / Disability interruption
• P： Whether the interrupt is suspended
• A： Whether the interrupt is responding

You can also click Peripherals Select the corresponding peripheral to view ：


Look at the function call stack ：

Be careful ：

• Keil When software simulation occurs no ‘write’ permission”,no ‘read’ permission Error of ： No settings debug Options DLL.
• Logic analyzer shall also be set DLL, And can only be used under software simulation , Cannot be used for hardware emulation , Otherwise prompt Unknown Signal., Or the following error occurs ：
