Response: The target (Kinetis Bootloader ) will return a GenericResponse packet withstatus code either set to kStatus_Success for successful execution of the command, or setto an appropriate error status code.13.3.8.6 FlashEraseRegion commandThe FlashEraseRegion command performs an erase of one or more sectors of the flashmemory or a specified range of flash within the connected SPI flash devices.The start address and number of bytes are the 2 parameters required for theFlashEraseRegion command. The start and byte count parameters must be 4-byte aligned([1:0] = 00), or the FlashEraseRegion command will fail and returnkStatus_FlashAlignmentError (0x101). If the region specified does not fit in the flashmemory space, the FlashEraseRegion command will fail and returnkStatus_FlashAddressError (0x102). If any part of the region specified is protected, theFlashEraseRegion command will fail and return kStatus_MemoryRangeInvalid(0x10200).Table 13-27.
