API specification

2.7.2

FlashECCLogicCheck()

Description

This function checks the ECC logic of the Flash. The API simulates a single or double bit

fault depending on the user input. If the simulated ECC error is not detected, then the error

code C90FL_ERROR_ECC_LOGIC is returned.

Prototype

UINT32 FlashECCCLogicCheck (PSSD_CONFIG pSSDConfig,

UINT64 dataVal,

UINT64 errBits,

UINT32 eccValue)

Arguments

Return values

Troubleshooting

The trouble shooting given here comprises of hardware errors and input parameter error.

Table 48. Arguments for FlashECCLogicCheck()

Argument

Description

Range

pSSDConfig

Pointer to the SSD

Configuration Structure.

The values in this structure are chip-dependent.

Please refer to Section 2.3 for more details.

dataValue

The 64 bits of data for which

the ECC is calculated. The

bits of dataValue are flipped

to generate single or double

bit faults.

Any 64-bit value.

errBits

Is a 64-bit mask of the bits

at which the user intends to

inject error.

Any 64-bit value, except zero.

eccValue

It’s a 32 bit value which has

to be passed by user. This

is calculated ny using an

offline ECC Calculator.

This is a corresponding ECC value for the data

value passed by the user.

Note: Same data words should be used in off line

ECC calculator and Flash ECC logic check API.
