1.1.3.4.14 DRV_MEMORY_GeometryGet Function

SYS_MEDIA_GEOMETRY* DRV_MEMORY_GeometryGet
(
    const DRV_HANDLE handle
);

Returns the geometry of the memory device.

This API gives the following geometrical details of the attached memory device:

• Media Property
• Number of Read/Write/Erase regions in the memory device
• Number of Blocks and their size in each region of the device

The DRV_MEMORY_Open() routine must have been called to obtain a valid opened device handle.

SYS_MEDIA_GEOMETRY - Pointer to structure which holds the media geometry information.

SYS_MEDIA_GEOMETRY geometry;
uint32_t readBlockSize, writeBlockSize, eraseBlockSize;
uint32_t nReadBlocks, nReadRegions, totalFlashSize;

if (true != DRV_MEMORY_GeometryGet(&geometry))
{
    // Handle Error
}

readBlockSize = geometry.geometryTable[SYS_MEDIA_GEOMETRY_TABLE_READ_ENTRY].blockSize;
nReadBlocks = geometry.geometryTable[SYS_MEDIA_GEOMETRY_TABLE_READ_ENTRY].numBlocks;
nReadRegions = geometry.numReadRegions;

writeBlockSize = geometry.geometryTable[SYS_MEDIA_GEOMETRY_TABLE_WRITE_ENTRY].blockSize;
eraseBlockSize = geometry.geometryTable[SYS_MEDIA_GEOMETRY_TABLE_ERASE_ENTRY].blockSize;

totalFlashSize = readBlockSize * nReadBlocks * nReadRegions;
