Define this if you have a SPI Flash memory device which you |
|
|
|
|
want to use for the environment. |

|
|
- CONFIG_ENV_OFFSET: |
|
|
|
|
- CONFIG_ENV_SIZE: |
|
|
|
|
|
|
|
|
|
These two #defines specify the offset and size of the |
|
|
|
|
environment area within the SPI Flash. CONFIG_ENV_OFFSET must be |
|
|
|
|
aligned to an erase sector boundary. |
|
|
|
|
|
|
|
|
|
- CONFIG_ENV_SECT_SIZE: |
|
|
|
|
|
|
|
|
|
Define the SPI flash's sector size. |
|
|
|
|
|
|
|
|
|
- CONFIG_ENV_OFFSET_REDUND (optional): |
|
|
|
|
|
|
|
|
|
This setting describes a second storage area of CONFIG_ENV_SIZE |
|
|
|
|
size used to hold a redundant copy of the environment data, so |
|
|
|
|
that there is a valid backup copy in case there is a power failure |
|
|
|
|
during a "saveenv" operation. CONFIG_ENV_OFFSET_REDUND must be |
|
|
|
|
aligned to an erase sector boundary. |

|
- CONFIG_ENV_SPI_BUS (optional): |
|
|
|
|
- CONFIG_ENV_SPI_CS (optional): |
|
|
|
|
|
|
|
|
|
Define the SPI bus and chip select. If not defined they will be 0. |
|
|
|
|
|
|
|
|
|
- CONFIG_ENV_SPI_MAX_HZ (optional): |
|
|
|
|
|
|
|
|
|
Define the SPI max work clock. If not defined then use 1MHz. |
|
|
|
|
|
|
|
|
|
- CONFIG_ENV_SPI_MODE (optional): |
|
|
|
|
|
|
|

Define the SPI work mode. If not defined then use SPI_MODE_3. |
