AT91SAM9263 is not booting with NAND Flash..........

Deal All,

I am using AT91SAM9263 Rev.B CPU, with NAND Boot-Strap from www.linux4sam.org.
CPU will not boot with 64MB (512b page, 16k/block) NAND Flash (ST/Numonyx make) NAND512W3A2C,
but I changed 256MB (2048b page, 64pages/block) NAND Flash (Micron make) MT29F2G08AACWP, CPU is booting well....

Can any one suggest me what may be the woring thing??

Thanks in advance.

Hi,

Have you looked at the source of this NAND Boot-Strap from www.linux4sam.org
?
It could be possible that the sector size is hardcoded for 2K sectors.
Until late last year (AFAIK) Linux treated the actual device's sector size
("HW sector size") and the
user space/kernel's side of drivers both as default 512 bytes. (this of
course has nothing to do with the bootstrap, but it
does affect the bootstrap's perception of sector sizes)
They are now differentiated, I think so far 2K or 512 B sector sizes are
only supported.
So it might be coincidence, but it sounds like that bootstrap is fixed for
2K sectors ???

This is just conjecture, hoping it might help.

Best Regards,
Kris

hi kiran,
i am working on AT91SAM9263 Rev B cpu with Nand 64MB (ST make)
and i got my bootstrap working... i am getting my bootstrap working but not able to get u-boot could u suggest ny thing on tht after getting bootstrap working the bord simply hangs...
in your case with 64MB NAND i guess something went wrong with page sizes were u uisng samll block size?

Thanks& Regards
Mahesh

Dear Mahesh,

OK,
I will send boot-strap & u-boot by tomorrow, try this one.

can u send ur boot-strap, u-boot & datasheet of NAND Flash.
also send address location for the same.

Thanks and regards,
Kiran

hai Mahesh,

Does your board display anything after the bootstrap is up?If yes can you
build your u-boot to use the default enviroment?
Are you burning the environment variables into Nand flash?

hi kiran,
i have attached bootstrap code have a look at it. as i said i got it working but not getting u-boot working . addresses u can see the board/... nandflash/9263.h
also send me your bootstrap + bootloader for 9263

Regards
Mahesh.

hi vishnu,
i get the prints from bootstrap on consol after booting from bootstrap but nothing from u-boot, and yes i have build the u-boot with environment variables in nand flash... but i have not tried keeping environment default i will try that...

Thanks

Dear Mahesh,

board is not booting with your bootstrap,
I am using NAND512W3A2C NAND Flash, (512b page, 16k/block, ST/Numonyx make).

find the attached bootstrap+uboot, it works with 512MB NAND Flash (Part # MT29F2G08AACWP, Micron make).
but not works with ST make NAND Flash.

can u send me NAND Flash part #, that u r using.

Regards,
Kiran
