我在使用 controlSUITE 中的flash例程来熟悉flash api（例程路径C:\ti\controlSUITE\device_support\f2803x\v130\DSP2803x_examples_ccsv5\flash_programming），发现在使用Flash_Program对flash进行写入时失败，状态码为30。例程中运行的Example_CsmUnlock、Flash_APIVersionHex 、Flash_APIVersion、Flash_Erase等api都正常。

我未对例程代码有做任何修改，仅仅基于F28034.cmd做了修改将api放入ram处理，想问一下这种情况该如何解决？
