hi all ,
I am trying to boot the DM368 custom Board from nand flash .i have downloaded the latest u-boot source code from this link.
http://arago-project.org/git/people/?p=sandeep/u-boot-davinci.git;a=summary
I am flashing Nand using SDcard boot and flashing utiltiy.
I am using nand flash 256MB size from Micron and the part no is MT29F2G08AADWP .
I have a problem with this u-boot. u-boot is not able to load the kernel image and i see the following errors.
Loading from nand0, offset 0x400000
NAND read from offset 400000 failed -74
