TI中文支持网Part Number:TMS320F280025Other Parts Discussed in Thread:C2000WARE
已经通过lin口把bin文件烧写入flash了，但是不知道一些配置如何配置，导致最后跳转到主程序main的时候进入Interrupt_illegalOperationHandler错误中断，请教下

额，抱歉直接把工程发上来的话其实像我们对工程不了解的诊断起来会有的吃力啊。
你的项目应该是要实现二次boot，不过用lin的方式boot我这边没有这方面的实操经验，但是TI是有提供一个基于SCI的二次bootloader例程的，你可以参考例程里面的跳转方法和跳转地址：
C:\ti\c2000\C2000Ware_4_01_00_00\driverlib\f28002x\examples\flash
,
xuan wang：
你好，要更新的一个程序，仿真时看到的flash地址数据和生成的hex文件数据不一致是怎么回事，好像生成的文件数据只取了低8位
,
Green Deng：
你是用什么工具生成的Hex文件？是用CCS自带的生成工具来生成的吗
,
xuan wang：
是的，不知道是不是没设置好，应该看看哪些选项
