- Define this if you have a DataFlash memory device which you
- want to use for the environment.
-
- - CONFIG_ENV_OFFSET:
- - CONFIG_ENV_ADDR:
- - CONFIG_ENV_SIZE:
-
- These three #defines specify the offset and size of the
- environment area within the total memory of your DataFlash placed
- at the specified address.
+ Define this if you don't want to or can't have an environment stored
+ on a storage medium. In this case the environemnt will still exist
+ while U-Boot is running, but once U-Boot exits it will not be
+ stored. U-Boot will therefore always start up with a default
+ environment.
config ENV_IS_IN_EEPROM
bool "Environment in EEPROM"
These two #defines specify the offset and size of the
environment area within the total memory of your EEPROM.
- - CONFIG_SYS_I2C_EEPROM_ADDR:
- If defined, specified the chip address of the EEPROM device.
- The default address is zero.
-
- - CONFIG_SYS_I2C_EEPROM_BUS:
- If defined, specified the i2c bus of the EEPROM device.
-
- - CONFIG_SYS_EEPROM_PAGE_WRITE_BITS:
- If defined, the number of bits used to address bytes in a
- single page in the EEPROM device. A 64 byte page, for example
- would require six bits.
-
- - CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS:
- If defined, the number of milliseconds to delay between
- page writes. The default is zero milliseconds.
-
- - CONFIG_SYS_I2C_EEPROM_ADDR_LEN:
- The length in bytes of the EEPROM memory array address. Note
- that this is NOT the chip address length!
-
- - CONFIG_SYS_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.
- - CONFIG_SYS_EEPROM_SIZE:
- The size in bytes of the EEPROM device.
-
- CONFIG_ENV_EEPROM_IS_ON_I2C
define this, if you have I2C and SPI activated, and your
EEPROM, which holds the environment, is on the I2C bus.
