28335 ADC Calibration not complete, check if device is unlocked and recalibrate

最近在跑一个28335的程序，编译没有错误，debug的时候跳出如下错误：

C28xx: GEL Output:

ADC Calibration not complete, check if device is unlocked and recalibrate.C28xx: GEL Output:

ADC Calibration not complete, check if device is unlocked and recalibrate.C28xx: GEL Output:

ADC Calibration not complete, check if device is unlocked and recalibrate.C28xx: GEL Output:

ADC Calibration not complete, check if device is unlocked and recalibrate.C28xx: Breakpoint Manager: Retrying with a AET breakpoint

C28xx: Trouble Setting Breakpoint with the Action "Finish Auto Run" at 0x9000: (Error -1066 @ 0x9000) Unable to set/clear requested breakpoint. Verify that the breakpoint address is in valid memory. (Emulation package 5.1.232.0)

C28xx: Error: (Error -1156 @ 0x0) Device may be operating in low-power mode. Do you want to bring it out of this mode? (Emulation package 5.1.232.0)

C28xx: Unable to determine target status after 20 attempts

C28xx: Failed to remove the debug state from the target before disconnecting.  There may still be breakpoint op-codes embedded in program memory.  It is recommended that you reset the emulator before you connect and reload your program before you continue debugging

这块28335的板子在仅运行PWM模块的小程序时，能够正常输出PWM波形，而且不会报错，但是运行较大型的工程文件的时候就会出现如上错误，求大神指点！！

    能不能下载程序到片内的Flash中？

    这个提示你，设备是否没有锁住，因此无法校准。你看看是不是有什么寄存器需要锁住才能正常运行，这几天看MSP430i2xx系列就发现如果使用内部的Flash需要解锁，操作，再锁定才能正常工作的。另外你这个还提醒可能工作于低功耗模式，根据提示你逐个排查一下。

    TI员工您好，我也遇到了类似问题，flash现在无法下程序，现在只有在RAM下并且BOOT模式选择为skip ADC calibration仿真器才能与DSP链接，程序可以load进去，但是无法运行，显示如下错误C28xx: Trouble Reading PC Register: (Error -1041 @ 0x0) The emulator reported an error. Confirm emulator configuration and connections, reset the emulator, and retry the operation. (Emulation package 5.0.747.0)
    C28xx: Can't Run Target CPU: (Error -1140 @ 0x9765) Lost debug connection to device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.747.0)

    请问我该如何解决

    Thanks for your sincere help!
