By default the page size corresponds to the block size (65536). Other option include the sector size (4096). config NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE 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. config NORDIC_QSPI_NOR_XIP bool "XIP (eXecute in place)" 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)" default 500 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. endif # NORDIC_QSPI_NOR
