FLASH烧写出现了问题，麻烦遇到同样问题的解答一下

C28xx: Error occurred during flash operation: Timed out waiting for target to halt while executing FlashAPIInterface28335V2_10.out
C28xx: Flash Programmer: Error encountered when writing to flash memory
C28xx: File Loader: Memory write failed: Unknown error
C28xx: GEL: File: E:\my28335\CONTROL_STRUCT_zyj4\Debug\CONTROL_STRUCT_zyj4.out: Load failed.

这是在烧写程序的时候出现的错误，根据提示，我觉得不是FLASH被锁了，但是也不清楚问题，希望遇到过的朋友解答一下，谢谢
