Erase operation failed because the pre-
compaction portion failed. The pre-compaction is
applied to all sectors on the device. The
FLASH_ST structure will return a fail address
corresponding to the first sector fails this step.


奇怪的是我用jtag仿真器将flash_api  code下载到dsp中单步调试，用串口调试工具发送握手报文和擦除指令时，flash_api  code正确调用了擦除函数，且返回值也是正确的0，一旦全速运行，用sdflash软件启动烧录过程，则返回值就成了24，报erase fail

请问这个错误是什么原因？应该如何解决？
