g_s32k144's Introduction

hacking S32K144

简介

S32K144是NXP推出的车规级别的MCU，ARM架构的内核。芯片在设计上考虑了功能安全的设计，可以达到ASIL B的级别。这方面我没有太多的ARM平台的经验，恰好借助这个平台了解一下。虽说按照一般的认知，SDK比自己手写驱动要简单。但是关于SDK的使用，我也没有太多经验。这次hack过程中研究一下这里面的技巧。除了驱动之外，尽量在这个平台上熟悉一下FreeRTOS的平台开发。

开发工具选择

编译器套件:选择NXP官方的S32DS for ARM。这是一个基于gcc的免费的开发套件，作为我们的学习选择还是不错的。
调试器:看到了开发板上自带了一个OpenSDA，这算是其中的一个选择。另外，我也准备了一个Jlink。

g_s32k144's Issues

osif.h file not found?

Hello Sir,
I was trying this S32K144_009_GPIO_LED code on my S32 Design Studio, I opened freertos_s32k144 from example, then i have replaced your generated code and sources folder but at the time of building the project, it is showing some error, could you guide us how can i use that project, what instructions should i follow.

Just a query regarding this main.c file?

this code will run infinite time correct?

#define COUNTER_LIMIT 100

    int counter = 0;

    for(;;) {       
        counter++;

        if(counter > COUNTER_LIMIT) {
            counter = 0;
        }
    }

why we need to put these below lines:- if defined(ghs) and what is GHS and IAR can you explain me in brief?
Many Thanks!

/* to avoid the warning message for GHS and IAR: statement is unreachable*/
#if defined (ghs)
#pragma ghs nowarning 111
#endif
#if defined (ICCARM)
#pragma diag_suppress=Pe111
#endif
return 0;
}
