Hello. I am using MDK5 now. (stm32f2xx) When I used MDK4 before, I set nand configuration for NAND Page Data Layout.
//////////////////////////////////////////////////////////////////////////// static U32 Init (NAND_DRV_CFG *cfg) {
/* Setup OneNAND Page Layout */ cfg->PgLay->Pos_LSN = 2; cfg->PgLay->Pos_COR = 1; cfg->PgLay->Pos_BBM = 0; cfg->PgLay->Pos_ECC = 8; cfg->PgLay->SectInc = 512; cfg->PgLay->SpareOfs = 2048; cfg->PgLay->SpareInc = 16;
/* Init NAND Driver Peripheral */ /* ... */ return RTV_NOERR; }

Can I use nand configuration in MDK5?
I modified a FS_Config_NAND_0.h like this
Connect to hardware via Driver_NAND# : 0 Device Number : 0 Bus Width : 8-bit Page Size : 4096+244 bytes // special setting. not default Block Size : 64 pages Device Size[blocks] : 4096 Page Caching : 8 pages Block indexing : 16 blocks Software ECC : Hamming (SLC) Drive Cache Size : 8 KB
and I programmed the sample like this
finit ("N0:"); printf("finit = 0x%x\r\n",stat) ; fmount ("N0:"); printf("fmount = 0x%x\r\n",stat) ; stat = 0 ; opt = "/FAT32"; stat = fformat ("N0:",opt) ; printf("fformat = 0x%x\r\n",stat) ; result : finit = 0x0 fmount = 0x9 fformat = 0x9 #define fsMediaError 0x09 // Media error
I don't know why I can not format a NAND Filesystem in KEIL5(MDK5).
But I succeeded to format a NAND Filesystem using a NAND Page Data Layout in KEIL4(MDK4).
Did you make sure, that you have your external memory controller properly configured?
I used a Micron NAND(MT29F8G08ABACA / 1GByte) and its features is like this
- Page size x8: 4320 bytes (4096 + 224 bytes) – Block size: 64 pages (256K + 14K bytes) – Device size: 8Gb: 4096 blocks 1 page = (4K + 224 bytes) 1 block = (4K + 224) bytes x 64 pages = (256K + 14K) bytes Minimum required ECC : 8-bit ECC per 540 bytes of data
