# S32K3 BSP 说明
2+
3+
## S32K344
4+
5+
### 1. 介绍：
6+
7+
基础工程：
8+
9+
- LPUART3(PD3-Rx, PD2-Tx) :
10+
- 每2s打印hello
11+
- finsh
12+
13+
使用软件包：SW32K3_S32M27x_RTD_R21-11_5.0.0
14+
15+
生成工具：S32 Design Studio for S32 Platform 3.5
16+
17+
18+
使用样板：
19+
20+
![](./img/使用样板.png)
21+
22+
### 2. 例程使用准备：
23+
24+
- 目前仅使用gcc编译，为了增加同通用性，例程尽量使用了寄存器操作。在编译前请将`bsp\nxp\S32K3\S32K344-core\libraries\s32k344_SDK`和`board`中的文件补充完整：
25+
26+
| 目录名 | 对应nxp目录 | 备注 |
27+
| -------------------- | ------------------------------------------ | --------------------------------------- |
28+
| header | BaseNXP_TS_T40D34M50I0R0\header | 寄存器定义（在nxp软件包目录下查找） |
29+
| include | | 在下一步中补充 |
30+
| Startup_Code\inc | Platform_TS_T40D34M50I0R0\startup\include | 芯片启动头文件（在nxp软件包目录下查找） |
31+
| Startup_Code\src | 生成模板工程\Project_Settings\Startup_Code | 芯片启动源文件 |
32+
| linker_scripts | 生成模板工程\Project_Settings\Linker_Files | 芯片链接脚本（在board中） |
33+
34+
- 在补充完成后：
35+
36+
1. 编译，寻找缺失头文件，在`BaseNXP_TS_T40D34M50I0R0\include`目录下查找并放入目录`include`
37+
38+
2. 重复步骤 1 直到缺失的头文件无法在`BaseNXP_TS_T40D34M50I0R0\include`目录下找到，或者不在是头文件缺失错误
39+
40+
3. 删除`include` 目录下的`Mcal.h`，将工程中所有的 `#include "Mcal.h"`替换为`#include "S32K344.h"`
41+
42+
4. 在`ststem.h`头部添加：
43+
44+
```c
45+
#define OsIf_GetCoreID() Sys_GetCoreID()
46+
#define MCAL_DATA_SYNC_BARRIER() __asm__(" DSB")
47+
#define MCAL_INSTRUCTION_SYNC_BARRIER() __asm__(" ISB")
48+
```
49+
50+
5. 删除`exceptions.c`中的`PendSV_Handler`和`SysTick_Handler`实现。
51+
52+
6. 修改`startup_cm7.s`：`main`改为 RTT 入口`entry`，删除 `_start:`
