Based on the project 39SF040_Programmer here https://github.com/doctorandrey/39SF040_Programmer Based on the code of 39SF040 / 39SF020A Programmer by Bob Szymanski Published 9/24/2015.
Connect Flash to Arduino mega according to the pins as defined in the source file. SD card pinout is as provided by Arduino, on pins 51-53.
Based on Arduino Mega 2650 and Standard SD Shield. Serial terminal speed 57600.
Quick serial commands list:
HELP - Shows this help
ID - Shows Chip ID
LS - Lists files on SD-card
DUMP arg1 arg2 - Dump to Serial EEPROM data; arg1 - start address, arg2 - data length
ES arg1 - Erase Sector; param1 - sector's start address
EC - Erase Chip
ETF arg1 arg2 arg3 - Writes EEPROM data to File; arg1 - filename, arg2 - start address, arg3 - data length
FTE arg1 arg2 - Program ROM File data to EEPROM; arg1 - filename, arg2 - start destination address
Example Usage:
FTE FIRMWARE.ROM 0x10000 - Writes file FIRMWARE.ROM to EEPROM starting from 0x10000
ETF FIRMWARE.ROM 0x10000 0x8000 - Writes EEPROM data starting from 0x10000 and length 0x8000 to file FIRMWARE.ROM
(ETF stands for Eeprom To File, FTE - File To Eeprom, etc.)
