1:first i use the nand flash type is MT29F8G08MAAWC,if i cann't modify the
address,the Manufacture and device id is always 0,and the hardware engineer
told me to modify it,then the id can be identify ok.when i change nand flash
type to HY27UG088 ,the same result it is!
2:the micron flash page size is 2048+64,and the HY27UG088 is also size.
3:we can do uart boot and i have test it ok,but i have xds560 emluator,it can
translate data easy!
4:if i use the MT29F8G08M,i have to add {0xD3, 128, 2048+64,23, 5},
/* Micron MT29F8G08AAA */ //add by duke 2009.2.9
item in the const NAND_DEVICE_INFO gNandDevInfo[]
5:I am surprising too,but the hardware engineer ask me to do it.

主题： RE: nand_programmer check all nand flash blocks error
Hi Duke Zuo,
We are also struggling with similar issue since few weeks. We have done some
investigation that might help you.
1. What NAND chip you are using?
2. What is the page size? As per TI, RBL does not support NAND having 4096 page
size
3. Are you able to do UART boot?
4. Have you modified anything in “NAND_Programmer.pjt” source code? If yes,
what are those?
5. It is surprising to see your changes related to ALE/CMD address, we are not
required to do so.
Regards,
Jitendra

Subject: nand_programmer check all nand flash blocks error
dear all:
I use a new nand flash for dm355 in my new borad,first i used Micron 1G
nand flash, the address have been modify:
#define NAND_ALE_ADDR ((volatile Uint8*)0x02000004) //from 0x02000008
#define NAND_CMD_ADDR ((volatile Uint8*)0x02000008) //from 0x02000010
if i use the old address, the Manufacture id and device id is always 0 when
read it.and the hardware told me to modify the address!but when I run the
programmer by jtag,the result is:
Started Nand programming
Manufacture ID 2c
device ID d3
find the NAND device in the table!
NANDInit() Successful
Enter the UBL File Name
D:\dvsdk_1_30_00_40\dvsdk_1_30_00_40\PSP_01_20_00_014\bin\dm355\ublDM355-nand.bin

It seemd all block is bad!!
When i skip the block checking(just return E_PASS in NANDCheckBadBlock()
function ),it can run ok,the ubl and uboot seems burning ok,but when i reboot
the board,it cann't boot!!
I have contact to the supporter by ti,they told me the RBL(rom boot
loader) can't support 128 pages of a block,so i changed a nand flash type
HY27UG088G whick 64 pages of a block,it seem the same result!
any one can help me?thanks a lot!!
