Using Keil File System on STM32F4 with NAND

Hi!
I have MT29F32G08CBACA Nand Flash device, and I need wear leveling.
This device have Page Size = 4096 user + 224 spare bytes. But in FS_Config_NAND_0.h a can chose only 4096+ 128. Will this device work with the Keil File System?

You can manually define page size in config file and you should be ok.

#define NAND0_PAGE_SIZE 4320

Devices with bigger spare area usually require 4-bit ECC per 512 bytes. This can be only supported by hardware, so check your device and hardware ECC support before using such device.

Hi.
I difined NAND0_PAGE_SIZE 4320.
I'm trying to do next code, drive N0 not formatted, it's okey becose never formatted before.
And when I do: stat = fformat ("N0:", "/LL");,
I get error and stat = 8.

static void Filesystem_Init (void)
{
        fsStatus stat;

        /* Initialize and mount drive "N0" */
  stat = finit ("N0:");
  if (stat == fsOK) {
    stat = fmount ("N0:");
    if (stat == fsOK) {
      printf ("Drive N0 ready!\n\r");
    }
    else if (stat == fsNoFileSystem) {
      /* Format the drive */
      printf ("Drive N0 not formatted!\n\r");
      cmd_format ();
    }
    else {
      printf ("Drive N0 mount failed with error code %x\n\r", stat);
    }
  }
  else {
    printf ("Drive N0 initialization failed!\n\r");
  }
}
static void cmd_format (void) {

        fsStatus stat;
        stat = fformat ("N0:", "/LL");

  if (stat == fsOK) {
    printf ("Format completed.\n\r");
  }
  else {
    printf ("Formatting failed. Code = %d\n\r", stat);
  }

}

About ECC: Minimum required ECC 24-bit ECC per 1080 bytes of data. It's from DS.
