器件型号：TMS320F280025

您好、专家！

使用闪存 API EraseSector 函数时出现 FMSTAT_FAIL()错误。使用此擦除功能时、我应注意什么？

当我进行调试时、我得到 oFlashStatus 的值为0x0100。我在《闪存 API 参考》中提到 FMSTAT、但我仍然不明白为什么会发生这个错误。

是否应使用 Fapi_getFsmStatus ()函数？导致此错误的常见原因是什么？

TMS320F28002x 闪存 API 版本1.57.00.00 (TI.com.cn)

谢谢。
恩亚

尊敬的 Vamsi：

我发现扇区擦除与链接文件的配置相关。

不能擦除 cmd 文件中某些段占用的地址空间？有什么需要注意的地方吗？

目前、FLASH_BANK0_sec2和 FLASH_BANK0_SEC4擦除失败。以下是我链接的文件的内容。
