STM32 Preschool Tutorial Part 3: Make the PC work, choose the software to develop

1.  Software and version selection

Requirements: Support STLink2 or future Jlink  V7 debugging interface (because STM32-SK uses this interface), be able to find ways to remove software restrictions, preferably with Chinese version help and interface, preferably with pure software simulation

Choice: RealView  MDK  3.23RPC or IAR  EWARM  4.42A (wait and see version 5).

2.  RealView  MDK  3.23RPC (Chinese version) installation and restriction removal

Step 1: Execute the installation program to complete the basic installation, and finally choose to add virtual hardware to facilitate pure software debugging.

Step 2: Execute the software, click File-->Licence  Manager, copy the CID data to the CID of the cracker, other options are as shown below, and then click Generate.

Step 3: Copy the LIC0 data to the LIC box of the software and click Add  LIC. Note that after adding the serial number, the Licence  Manager will calculate the validity period corresponding to this number. If it expires, it will be displayed in red. You need to click Generate of the cracking software again and calculate another one and fill it in.

Step 4:  Copy the files (two DLLs) required by ST-LINKII-KEIL Driver to KeilARMBIN and replace the original files. Step 5: Open the TOOLS.INI file in the Keil installation directory, add the line TDRV7=BINST-LINKII-KEIL.dll("ST LinkII  Debugger")

under the [ARM], [ARMADS], and [KARM] projects  , and save the changes. Step 6: Open MDK, select ST LINKII  Debugger in the Debug option of the project options  , and select ST LINKII  Debugger in the Utilities option  . After completing the above steps, the relevant configuration of ST-LINKII is completed and it can be used as a debugger. Note: Currently, ST-LINKII does not support the Download and Erase commands in the Flash menu. The program is automatically loaded into the flash for debugging when using Start/Stop  Debug  Session. 3.  Installation and cracking of IAR  EWARM  4.42A Step 1: Start/Run…/CMD to display the DOS interface, execute iarid.exe>>ID.TXT to get the local ID code, copy this ID code, and then execute iarkg.exe  ID code>>Lic422A.TXT to get a set of registration codes. Step 2: Use EWARM-EV-WEB-442A.exe (30-day limited version, other versions cannot use the registration code in the first step), execute the installation program to complete the basic installation, and you need to add the registration code calculated in the first step during the process. You can cancel the time limit, but only one of the group is valid, and you need to experiment. 4.  Link the hardware debugging program RealView  MDK: Find a basic program for STM32-SK, preferably only about IO and different from the current board program, so that you can see the results on the board, click Project/open  project. For example, GPIO, TIMER (the other two routines are about serial ports, and you need to connect to the serial port to see the running results). Use "Open  Project" to open, and then set the linker in Option and the project in Utilities to "ST  LinkII  Debuger". Compile the program, and then use "Start/Stop  Debug  Session" to write the program. IAR  EWARM: Same as above, find a routine that meets the conditions. Open an eww project file, right-click and select Option, select "Third-Party Driver" in Debuger  , and add "$PROJ_DIR$..ddlSTM32Driver.dll" in "Third-Party  Driver". Use "Make" or "Rebuild  All" to compile the program, and click "Debug" to burn it into Flash. Use "go" in the debug bar and so on to run the program. Note: Since the current version of MDK is incompatible with the ST-LINK-II programmer I have, all subsequent work will use IAR.
