TMS320F28069: 芯片锁定？

此芯片第一次烧录测试程序，可以链接仿真器，代码烧录进flash时报以下错误

Load program Error
File: D\DSP CSS\Sci test\Debug\Sci test,out: Load failed.

C28xx：GEL Outout.
Device Calibration not complete, check if device is unlocked and recalibrate.C28xx: GEL Output:
Device Calibration notcomplete, check if device is unlocked and recalibrate.C28xx: Flash Programmer: Device is locked or not connected. operation cancelled

C28xx: File Loader: Memory write failed: Unknown error
C28xx: GEL: File: D:\DSP_CSS\Sci_test\Debug\Sci_test.out: Load failed

同样烧录不进ram，报错为

Load program Error
File: D\DSP CSS\Sci test\Debug\Sci test,out: a data verification error occured,Load failed.

此代码烧同类型芯片好用，下附代码
