1 wire uart comms

uart protocol for flash programming

01 - soh = start of heading(command sending to chip)

02 - stx = start of text/start transmission(marker for start of reply from chip)

03 - etx = end of text/end transmission(marker for end of reply from chip/end of command data sent to chip)

format of messaging

<stx/soh><length><command/error><checksum><etx>

checksum

Command frame: LEN + COM + all of command information

Data frame: LEN + all of data

get version cmd

01 01 c5 3a 03 = get version c5

02 01 06 f9 03 = ack response

02 06 00 00 00 01 00 00 f9 03 = 00 00 00 01 00 00

device version:0.00

firmware version: 1.00

DV1: Integer of device version (fixed to 00H)

DV2: First decimal place of device version (fixed to 00H)

DV3: Second decimal place of device version (fixed to 00H)

FV1: Integer of firmware version

FV2: First decimal place of firmware version

FV3: Second decimal place of firmware version

verify? 0x14 cmd

01 01 14 eb 03 = 14 verify flash?

02 01 10 ef 03 = 10 protection error

blank block check cmd

01 08 32 00 00 00 0b ff ff 00 bd 03 = blank block check

SAH, SAM, SAL: Block blank check start address (start address of any block)

SAH: Start address, high (bits 23 to 16)

SAM: Start address, middle (bits 15 to 8)

SAL: Start address, low (bits 7 to 0)

EAH, EAM, EAL: Block blank check end address (last address of any block)

EAH: End address, high (bits 23 to 16)

EAM: End address, middle (bits 15 to 8)

EAL: End address, low (bits 7 to 0)

D01: 00H: When performing a block blank check for a single block 01H: When performing a blank check for the complete area before erasing the chip

start address:0x000000

end address:0x0bffff

d01:00 = single block

chip erase cmd

01 01 20 df 03 = chip erase

reply

02 01 10 ef 03 = protection error
