struct nand_read_write
Defined at line 57 of file fidling/gen/sdk/banjo/fuchsia.hardware.nand/fuchsia.hardware.nand/banjo/c/fuchsia/hardware/nand/c/banjo.h
Declarations
A single operation can read or write an arbitrary number of pages,
including out of band (OOB) data for each page. If either regular
data or OOB is not required, the relevant VMO handle should be set to
ZX_HANDLE_INVALID.
Note that length dictates the number of pages to access, regardless
of the type of data requested: regular data, OOB or both.
The OOB data will be copied to (and from) a contiguous memory range
starting at the given offset. Note that said offset is given in nand
pages even though OOB is just a handful of bytes per page. In other
words, after said offset, the OOB data for each page is located
nand_info.oob_size bytes apart.
For example, to read 5 pages worth of data + OOB, with page size of
2 kB and 16 bytes of OOB per page, setting:
data_vmo = oob_vmo = vmo_handle
length = 5
offset_nand = 20
offset_data_vmo = 0
offset_oob_vmo = 5
will transfer pages [20, 24] to the first 2048 * 5 bytes of the vmo,
followed by 16 * 5 bytes of OOB data starting at offset 2048 * 5.
