The write-in data of 256 bytes, wirelessly more new procedures base area location, sequence write data into FLASH (including MCU's
FLASH outside FLASH and MCU).And smart machine 2 and external control equipment 1 will carry out CRC check to the data of write-in.
The main inspection completed to write-in data correctness of CRC check operation, verification are that unit is verified with Sector (sector), such as
Fruit CRC check failure, then after being wiped as unit of Sector, re-start write operation.
Specifically, smart machine 2 sends multiple write instruction sequences, write instruction sequence for a complete more new content
The data volume of column and the amount of storage of sector location are consistent, i.e. a write instruction sequence writes a full sector.
When control equipment 1 receives write instruction sequence and is fully written a sector location in vitro, pass through communication unit
It sends to smart machine 2 for the checking command (cyclic redundancy check calculated according to write-in data) for currently writing full sector location.
Smart machine 2 verifies this checking command, then continues to send the write-in for being directed to next sector location if the verification passes
Instruction sequence, for the rewritten instructions for currently writing full sector location, (write-in before repeating transmission refers to feedback if verifying failure
Enable sequence).Until whole write instruction sequences send and are written and finish.
