API specification

Assumptions

It assumes that the Flash block is initialized using a ‘FlashInit()’ API.

3.6.5

ProgramVerify()

Description

The 'ProgramVerify()' API checks if a programmed Flash range matches the corresponding

source data buffer. In case of mismatch, the failed address, destination value and source

value are saved and relevant error code is returned.

Prototype

UINT32 ProgramVerify (PSSD_CONFIG pSSDConfig,

UINT32 dest,

UINT32 size,

UINT32 source,

UINT32 *pFailAddress,

UINT64 *pFailData,

UINT64 *pFailSource,

void (*CallBack)(void));

Arguments

Table 16. Programming algorithm for FlashProgram()

Address space to be

programmed

Description

LAS or MAS or Shadow Row

Programmed linearly double word by double word.

HAS

Programmed linearly double word by double word alternately

across each bank.

LAS and MAS

Programmed in parallel until programming in one address space

finishes. The remaining double words are programmed linearly in

the other address space.

MAS and HAS

Program MAS linearly. Once programming finishes, HAS is

programmed in parallel.

LAS, MAS and HAS

First programmed in parallel for LAS and MAS. Once

programming finishes in both the address spaces, HAS is

programmed in parallel.

Table 17. Arguments for ProgramVerify()

Argument

Description

Range

pSSDConfig

Pointer to the SSD

Configuration Structure.

The values in this structure are chip-dependent.

Please refer to Section 3.3 for more details.

Dest

Destination address to be

verified in Flash memory.

Any accessible address aligned on double word

boundary in main array or shadow row.
