TMS320F280039C: VDDIO上电后到进入main函数之前这段时间很长

Part Number: TMS320F280039C


基于LAUNCHXL-280039C的开发板的工程项目,VDDIO上电后到进入main函数之前的这段启动时间,会随着项目代码和功能的增多而变长。

通过Debug得知,在进入main函数之前先后经过了f28003x_codestartbranch.asm ---> boot28.asm ---> _args_main ---> main,

另外,.data段增加4000个Bytes后,启动时间也会随之变长17ms左右,

这部分启动时间具体受哪些因素影响?如果想压缩这部分启动时间,有何修改建议?
