SNANDer - Serial Nor/nAND/Eeprom programmeR v.1.7.8 by McMCC

Usage: -h display this message -d disable internal ECC(use read and write page size + OOB size - On-die ECC) -o manual set OOB size with disable internal ECC(default 0) -I ECC ignore errors(for read test only) -k Skip BAD pages, try read or write in to next page -L print list support chips -i read the chip ID info -E select I2C EEPROM {24c01|24c02|24c04|24c08|24c16|24c32|24c64|24c128|24c256|24c512|24c1024} select Microwire EEPROM {93c06|93c16|93c46|93c56|93c66|93c76|93c86|93c96} (need SPI-to-MW adapter) select SPI EEPROM 25xxx {25010|25020|25040|25080|25160|25320|25640|25128|25256|25512|251024} -8 set organization 8-bit for Microwire EEPROM(default 16-bit) and set jumper on SPI-to-MW adapter -f set manual address size in bits for Microwire EEPROM(default auto) -s set page size from datasheet for fast write SPI EEPROM(default not usage) -e erase chip(full or use with -a [-l]) -l manually set length -a

manually set address -w write chip with data from filename -r read chip and save data to filename -v verify after write on chip

Examples:

  1. Get info Flash.
