Hi, we have purchased a AT91SAM9261-EK and we trying to get the WinCE demo to work.

We have tried many many times with different example, different computers and using different versions of Samba without any success.

All the flashing is going ok and we enter values in the setup meny according to the guide, but when we
start the system and the WinCE is supposed to start the terminal window shows the following and then nothing happens:

Code:

INFO : Low Level Init : OK
Dataflash init OK
Starting eboot ...
Ã¿ serial initialized ........OK

Microsoft Windows CE Bootloader Common Library Version 1.4 Built Sep 24 2007 13:

Any helpful information is really appreciated.

I also try load NK.nb0 by Samba any version into nandflash, it doesn`t work. But when I load image by Ethernet from PB, it work!!!

May be samba and eboot have different methods for nandflash access (pagesize, ...)?

I compare sources eboot and CE nandflash driver, they are identical.

Ð•herefore I need help too...

Hello guys,

Do you have a Micron or a Samsung nandflash on your boards?

Hi gpouly
I have a Micron 29F2G08AAC.

Could the reson be wrong type of flash?

The board have a white sticker with BOM 006.

Thanks,
Jon

Yes this is the reason. For the moment the demo does not work with Micron nandflash (wrong nandflash timings). Adeneo who develop the demo) is currently working on it.

Thanks for the answer about wrong nandflash timings. However, it would be good if Atmel/Adeneo could deliver working example for such an expensive development kit, or at least inform customers about non-working examples!

If we replace the Nandflash will it work? If so, do you have a part number for a working type of Nandflash?

Hi JonLis,

I agree with you but this problem has been found recently. Replacing nandflash won't solve the problem. You should try to contact your local FAE or distributor to start an RMA procedure.

Sorry yanker I missed your answer.
You should try to perform a "scrub nandflash" with the dedicated SAMBA command then try to re-program the demo.
