Some DM368 systems get stuck at kernel boot

Hi.

About 3% of our boards gets stuck when the kernel is booting, and replacing the DM368 chips on these boards fixes the problem.

We are using DVSDK 2

The last print before it gets stuck is:

"nand_davinci nand_davinci.0 Using 4-bit hardware ECC"

And more precisely, it gets stuck when calling the function "nand_flash_init(info);"   inside drivers/mtd/nand/davinci_nand.c

I've tried to remove this line just to see what happens, and it just got stuck a little later somewhere inside the "nand_scan(info-mtd, 1)" call.

Can anyone help?

Thanks!

    Remove the NAND driver completely and see whether it boots up or not?

    If it boots then try to change the NAND timing and see whether it works or not. Also can you try the same with a later version of DVSDK like DVSDK 4.02?
