4Gbit NAND flash driver question

[vincent]

Hi:

we change NAND flash from 1Gbit(128M K9F1G08U0A) to 4Gbit(512M
HY27UF084G2M)
i update souce code fmd.cpp as the following:

========
case 0xADDC: //flash ID
{
NAND2KFMD *nand2K;
nand2K = new NAND2KFMD();
//memcpy(NandSpace,&nand2K,sizeof(nand2K));
Nand = (NandInterface*) nand2K;// NandSpace;
//Nand = (NandInterface*) NandSpace;
Nand->SetNandType(NAND2K);
Nand->SetSectorStartAddr((RESERV_BYTE / 2048 + 63)/ 64 * 64);
Nand->SetLineCycle(3); //row cycle 2->3
Nand->SetNandBlockCount(4096); //total blocks
Nand->SetNandPageCount(64); //pages counts in one block

}
break;
======

i can boot successfully and use bootloader to format nandflash successfully.
but after i download OS image and boot the OS, the error appear as the
following:

========

i traced detailly ,found when the OS check flash ,the block cross after
0x200 sectors
as the following message:(sector count 0,1,2

should i update something else or what problems happend??

hope to get your response soon.

Thanks and Best Regard.
