1. 调试所遇部分问题

1.1 安装S32DS编译器和补丁方法

/dongganxiao_maidou/article/details/80802223

SDK使用最新版本

1.2 S32DS编译生成Hex文件的方法

方法1：

/u010875635/article/details/85047313 （实测未生成hex）

方法2：

Project -> Properties -> C/C++ Build：

可生成hex文件。（hex文件INCA是否识别，待验证）

1.3 S32DS 修改默认BGA封装

可在components Library –> Processors中替换成144封装（不更换也未影响调试）。

1.4 MPC5744P System Clock

系统时钟频率 > 160M 程序无法运行提示错误“No source available for "0x1000000"，原因不详。
