Flash Driver PDD IOCTLs (Windows Embedded CE 6.0)
1/6/2010
The following table shows the flash driver PDD IOCTLs with a description of the purpose of each.
| Programming element | Description |
|---|---|
This IOCTL copies data from multiple source sectors to destination sectors. |
|
This IOCTL erases multiple, possibly noncontiguous, blocks. |
|
This IOCTL queries the status of a specific block. |
|
This IOCTL retrieves identity information for the flash part, such as the manufacturer ID and serial number. |
|
This IOCTL retrieves life cycle information for each of the flash regions, such as number of typical erases per block. |
|
This IOCTL retrieves the physical sector address. If XIP support is desired, then this IOCTL must be implemented. |
|
This IOCTL queries for the number of flash hardware regions. |
|
This IOCTL retrieves region information from the flash platform dependent driver (PDD) and returns an array of FLASH_REGION_INFO structures, where each element of the array corresponds to a flash hardware region. Flash hardware regions have fixed physical block boundaries and may have different characteristics, such as sector size and block size. |
|
This IOCTL locks one or more contiguous ranges of physical blocks; such that block can not be unlocked without a power reset. If support for block locking is desired, then this IOCTL must be implemented. |
|
This IOCTL sets the status of a specific block. |
|
This IOCTL reads data and/or spare area from multiple, possibly noncontiguous, sectors. |
|
This IOCTL writes data and/or spare area to multiple, possibly noncontiguous, sectors. |
