how does NFC_LDD map pages to blocks/pages?

bowerymarc — Thu, 29 Aug 2013 19:31:47 GMT

The WritePages and ReadPages API in NFC_LDD only asks for page number, and not block number. But erase blocks wants blocks. I need to know the mapping of pages to blocks for this to work, otherwise how can I know which page to erase and then write?

Is is simply blockNumber x NAND_FLASH_PAGE_SIZE + pageNumber?

or blockNumber x NAND_FLASH_PHY_PAGE_SIZE + pageNumber?

thanks,

Marc

Hello,

please check the details from our development team below. Anyway we will improve the documentation or will add some #define for next release:

These symbols are defined in NFC componenets header file:

#define NAND_FLASH_PAGE_COUNT 0xYYU
#define NAND_FLASH_BLOCK_COUNT 0xYYU

You can define new symbol NAND_FLASH_BLOCK_PAGE_COUNT

#define NAND_FLASH_BLOCK_PAGE_COUNT (NAND_FLASH_PAGE_COUNT / NAND_FLASH_BLOCK_COUNT )

and use folowing macro for page address to block address mapping:

#define GetBlockAddressFromPageAddress(_PageAddress_) (_PageAddress_ / NAND_FLASH_BLOCK_PAGE_COUNT)
