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><data><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
