1.1.4.4.7 DRV_NAND_FLASH_IdRead Function

C

bool DRV_NAND_FLASH_IdRead(const DRV_HANDLE handle, uint32_t *readId, uint8_t address)

Summary

Gets identifier codes from NAND Flash.

Description

This routine read identifier codes from NAND Flash.

Preconditions

The DRV_NAND_FLASH_Open() routine must have been called for the specified NAND Flash driver instance.

Parameters

ParametersDescription
handleA valid open-instance handle, returned from the driver's open routine
readIdPointer to 32-bit unsigned int into which ID will be stored
addressAddress to be send after command cycle. Address 0x20 is used for ONFI compliant Flash.

Returns

True - If ID read successfully from the Flash.

False - If invalid handle.

Example

#define NAND_FLASH_ADDR_ONFI_SIGNATURE 0x20
uint32_t readId = 0;
DRV_HANDLE handle; // Returned from DRV_NAND_FLASH_Open

if (DRV_NAND_FLASH_IdRead(handle, &readId, NAND_FLASH_ADDR_ONFI_SIGNATURE))
{
    // ID read successfully
}

Remarks

This routine will block for hardware access.
