|
help |
|
When CONFIG_FLASH_PAGE_LAYOUT is used this driver will support |
|
that API. By default the page size corresponds to the block |
|
size (65536). Other option include the sector size (4096). |

|
int "Size of a stack-based buffer to handle writes not supported by QSPI" |
|
default 4 |
|
help |
|
The QSPI peripheral uses DMA and can only write data that is read |
|
from a word-aligned location in RAM. A non-zero value here enables |
|
a stack buffer to be used for any source data that does not meet |
|
these restrictions. Such data will be copied into this buffer to |
|
allow the write to proceed. Multiple transfers will be initiated |
|
if the data is larger than the configured size. |
|
Must be a multiple of 4. When set to 0, the feature is disabled. |

depends on SOC_NRF5340_CPUAPP |
|
help |
|
Enable setting up the QSPI NOR driver to allow for execution of code |
|
stored in QSPI XIP region. Note that for this functionality to work, |
|
the QSPI NOR init priority must be set so that no XIP code in the |
|
QSPI NOR flash chip is executed until the driver has been setup. |
|
This will also disable power management for the QSPI NOR flash chip. |

config NORDIC_QSPI_NOR_TIMEOUT_MS |

int "Timeout for QSPI operations (ms)" |

|
help |
|
The QSPI peripheral operation timeout in milliseconds. |
|
Primarily intended for long running operations such as |
|
a flash sector erase. The 500 ms default allows for |
|
most typical NOR flash chips to erase a sector. |
