iMX6Q NAND Boot issue in WinCE

[KeshavaGN]

Hi all,

I'm trying to boot eboot.nb0 from NAND. (Micron, MT29F4G08ABBDA) in WinCE7.

Processor: i.MX6Q

I have successfully booted u-boot.bin from NAND using kobs-ng tool in linux.

Also, if i use modified eboot.nb0 instead of u-boot.bin in kobs, it is booting without any problem.

But when i use MFGTool (in WinCE) for flashing eboot.nb0, it is not booting.

Following is the nanddump output when i am using kobs (linux) for flashing:

Here, why we are getting first 12 bytes as zeros? (METADATA_SIZE is set to 10). Why two additional zeros?

In WinCE (Using MFGTool):

In WinCE, it is not at all booting.

Where is the mistake?

If metadata size difference is the problem , how i can solve it? ( I have also tried by changing METADATA_SIZE = 12, which increases metadata size, but not booting.)

What are those two extra bytes in linux (kobs)?

Please help.

Thanks.

Hi,

Solved.

Eboot is booting now.

Please help: iMX6Q NAND Boot issue in WinCE

Thanks.

Keshava G N

[andrew_questps]

One point would be that the image you use in the MfgTool needs to know about the flash you are using, so I had to recompile the UUT versions of WinCE with the correct flash selected.

There was also an issue with FMD_Init where it didn't reconfigure it's details once you had used the lookup table, a couple of the values were defaulting to the #defines for a specific nand chip. I had to add the call CSPNAND_Init again once Eboot had run through the lookup table in Nandtypes.h or it was messing around with the bad block tables.

That is my new FMD_Init. I also have to support a flash that uses 2 bad block table blocks - ie BBMarkNum = 2 which is why I have the extra debug.

[KeshavaGN]

Hi Webster,

I ensured that my NAND flash values are updating.

Now, while comparing the data written in NAND (ie: FCB and DBBT) in linux and in WinCE, i am doubting on ECC values written using WinCE.

Can you post the ECC calculation procedure in your code?

Thanks .

With regards,

Keshava G N

[andrew_questps]

I haven't had to change anything to do with the ECC calculation as my chip only uses 4-bit ECC.

[KeshavaGN]

Hi Webster,

Do you know how (and where in source code) "metadata" is written in NAND?

Can we edit it?

Thanks.

With regards,

Keshava G N

[HuangShijie]

The metadata is written with the first data chunk(most of the time, it's 512bytes).

You can write some data in the metadata, but after you have written the metadata to nand, you can not change it any more.

Of course, if you erase the block again, you can write some other data to the metadata again.

[KeshavaGN]

Hi HuangShijie ,

Do you have any idea about my issue: iMX6Q NAND Boot issue in WinCE
