The length in bytes of the EEPROM memory array address. Note

that this is NOT the chip address length!
|
||||
|
||||
- CFG_I2C_EEPROM_ADDR_OVERFLOW:
|
||||
EEPROM chips that implement "address overflow" are ones
|
||||
like Catalyst 24WC04/08/16 which has 9/10/11 bits of
|
||||
address and the extra bits end up in the "chip address" bit
|
||||
slots. This makes a 24WC08 (1Kbyte) chip look like four 256
|
||||
byte chips.
|
||||
|
||||
Note that we consider the length of the address field to
|
||||
still be one byte because the extra address bits are hidden
|
||||
in the chip address.
|
||||
|
||||
- CFG_EEPROM_SIZE:

The size in bytes of the EEPROM device.

- CONFIG_CRC32_VERIFY
|

Add a verify option to the crc32 command.

The syntax is:
|

|
||||
=> crc32 -v <address> <count> <crc32>
|
||||
|
||||
Where address/count indicate a memory area
|

and crc32 is the correct crc32 which the

area should have.
