dm8168 can't boot uImage from nand flash

lowen lin

Prodigy 40 points

Hello all;

images of u-boot and uImage were flashed to nand flash memory via u-boot. And then I want to

boot from the nand flash memory and the filesystem is mounted from network .There are some errors

occoureed ,i can't fix them .I doubt the problem result in NAND ECC algorithm selection .because

Would you give me some suggestions ? Thanks a lot! There are some details below.

There is no reliable way to recover them.

Use this command only for testing purposes if you

are sure of what you are doing!

Really scrub this NAND flash? <y/N>

hello idle;

thank you for your reply.but I can't fix it yet followed your way. Would you have another solution?I am looking forward to hearing from you .

Hi, lowen lin!

Can you try burn another kernel image smaller size? In this forum I saw some messages about problems when flashing large kernel. I use latest ezsdk_5_03_01_15 and my custom kernel size about 2.5MB.

Lowen Lin,

Immediately after flashing have you tried booting the kernel?

Lowen,

Is this a custom board or EVM? Did you try using "nandecc hw 2" or using sw ecc?

Can you do this simple experiment?

Create a pattern in memory or a file which is of 2K in size. Make sure the data is correct by doing memory dump using "md " command in u-boot. Then erase and write this 2K data to the NAND after setting "nandecc hw 0".

Just read back the 2K data from NAND to a different RAM address offset and compare whether the data is proper or not. If its improper do a "nand dump " of the particular NAND offset.

Hi, Lowen lin!

1) May be there are short circuits between adress/data lines on NAND? (but u-boot was burned successfully) Open box there NAND is placed and carefully insert it again.

2) Image uImage-dm816x-evm.bin - have the same format as uImage in linux/arch/arm/boot/uImage ?

May be this help you.
