LPC55 Flash

[Zhang_123]

Call FLASH_Program write 512 bytes, Then call FLASH_VerifyProgram for validation，FLASH_Program returns normal, but FLASH_VerifyProgram returns error code 116，  Next, write according to the flash address order, and the error code returned by the FLASH_Program is 102，

 After the above problem, it is found that the part of the corresponding flash address that has no operation, such as bootloader, has also been abnormal.

      Help confirm that when this error code appears, what operations are done inside the chip?
