eeprom

eeprom(8)						       System Administration							 eeprom(8)

NAME

       eeprom - reads and writes 24Cxx EEPROMs connected to I2C serial bus.

SYNOPSIS

       eeprom [-d dev] [-a adr] [-p pgs] [-w] [-y] [-f file]

DESCRIPTION

       eeprom  can  be	used  for reading from / writing to i2c-eeproms like the popular 24C16, 24C08, 24C04, etc.  In contrast to eeprommer which
       supports 24C256-type eeproms (24C16s) this tool works with 1-byte addresses!

NOTE

       Don't forget to load your i2c chipset and the i2c-dev drivers.

       Pages/addresses:
	   eeproms with more than 256 bytes appear as if they
	   were several eeproms with consecutive addresses on the bus
	   so we might as well address several separate eeproms with
	   increasing addresses

PARAMETERS

       dev    device, e.g. /dev/i2c-0	 (def)

       adr    base address of eeprom, eg 0xA0 (def)

       pgs    number of pages to read, eg 8 (def)

       -w     write to eeprom (default is reading!)

       -y     suppress warning when writing (default is to warn!)

       -f file
	      copy eeprom contents to/from file (default for read is test only; for write is all zeros)
