DESCRIPTION: Copies the EEPROM memory to a binary file (or stdout) on the Raspberry Pi. The Raspberry Pi GPIO SPI0.1 is used as interface to the SPI EEPROM (24 bit address, at least a 1024 Kibit type, 256 byte page). The generated data is written to the standard output stream or to a file. Caution: Overwrite file if it exists. Use > for redirecting (save the file) or | for piping to another command (e.g. hexdump).

size [Kibit]	address bits	page size [byte]
1, 2	8	16
4, 8, 16	16	16 (some 32)
32, 64	16	32
128, 256	16	64
512	16	256
1024, 2048	24	256

OPTIONS

Non argument options that are duplicated on the command line are not harmful. For options that require an argument, each duplication will override the previous argument value.

-s hexadr: start address in hex (0 is default)
-e hexadr: end adress in hex (0x1FFFF is default)

Added:

-p number: page size in bytes (256 is default)
-a number: address bits (8, 16, or 24; 24 is default)
