03 The foundation of development, the platform emerges

I often use IAR as my development environment. I checked the Nations.N32G430_Library.1.0.0 in the documentation and found that only IAR projects are used in ICACHE_CoreMark under FLASH. The other examples are based on Keil. I caught the fish that slipped through the net! However, I still plan to rebuild the test project based on IAR8.30.

First, use Nations Device PACK Add To IAR Tool.exe software to add chip information in the target IAR. The operation is very simple. Just find the installation directory of IAR and install it.

Next, open IAR and create a new project;

Create the following folders:

CMSIS, stores system files;

Libraries, which store manufacturer-level hardware firmware;

Startup, stores startup files;

USER, to store user files;

The following is the project configuration:

Select the project name - open Options, select the device, previously Pack allowed us to discover the target chip;

To configure CMSIS, one method is to use the kernel file that comes with IAR, and the other is to add the files provided by the manufacturer to the CMSIS we created ourselves. National Technology provides these files. In order to avoid differences, do not check Use CMSIS;

Configure include, and be sure to add the folders where the corresponding C files and header files are located;

Configure output files;

Configure Linker configuration;

Simulation configuration: The onboard debugger is the standard CMSIS DAP. Note that you must select SWD . The default is JTAG. This small detail bothered me for a long time when I downloaded the program later.

Select the correct FlashLoader;

At this point, the IAR configuration is basically completed. There is no need to write a specific program. Make it first to check if there are some unknown configuration errors. You can modify them according to the prompts.

Error reporting and modification:

Fatal Error[Pe035]: #error directive: "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)" G:\s-software program\j-evaluation\20220909 N32G430_eva\CMSIS\core\core_cm4.h

Solution: Add __FPU_PRESENT in Option---C++--define;

Fatal Error[Pe1696]: cannot open source file "log.h" G:\s-software program\j-evaluation\20220909 N32G430_eva\USER\src\main.c

What is log.h? It just has a redirection and initialization, which should be removed after the subsequent changes.

Error[Pe020]: identifier "FILE" is undefined G:\s-software program\j-evaluation\20220909 N32G430_eva\USER\src\log.c

Solution: Change the library setting to Full.

What is log.h? It just contains a redirection and initialization. You can remove these after subsequent changes. You can just include this log.c for easy printing.

I usually use the LED status to indicate, and then check it through online debugging, and rarely use printing

I still like IAR, ahahaha.

I really like what I often use. I get used to it.

I have never used IAR, I usually use Keil. I wonder how difficult it is to get started with it?

It's all a matter of habit. Once you get used to it, it will be easy.

There is corresponding Pack software on the official website, which is very convenient to add
