DRV_SST39_GeometryGet Function

C

bool DRV_SST39_GeometryGet(const DRV_HANDLE handle, DRV_SST39_GEOMETRY *geometry)

Summary

Returns the geometry of the device.

Description

This API gives the following geometrical details of the DRV_SST39 PROM:

Number of Read/Write/Erase Blocks and their size in each region of the device.

Preconditions

DRV_SST39_Open must have been called to obtain a valid opened device handle.

Parameters


Param	Description
handle	A valid open-instance handle, returned from the driver's open routine
geometry	Pointer to flash device geometry table instance

Returns

True if able to get the geometry details of the flash. False if the handle is invalid or errors occurs.

Example

DRV_SST39_GEOMETRY flashGeometry;
uint32_t readBlockSize, writeBlockSize, eraseBlockSize;
uint32_t nReadBlocks, nReadRegions, totalFlashSize;

DRV_SST39_GeometryGet(myHandle, &flashGeometry);

readBlockSize  = flashGeometry.readBlockSize;
nReadBlocks = flashGeometry.readNumBlocks;
nReadRegions = flashGeometry.readNumRegions;

writeBlockSize  = flashGeometry.writeBlockSize;
eraseBlockSize  = flashGeometry.eraseBlockSize;

totalFlashSize = readBlockSize * nReadBlocks * nReadRegions;

Remarks

None.
