    The first message is not really an error; it is telling you that U-Boot could not read the environment in NAND and it is pulling it from the U-Boot image.

    The second I am not sure about and have a few questions.

    1. What instructions are you following to burn Android to NAND?

    2. Which ECC schemes are you using to burn the images?

    3. Have you setup the MTD drivers to use the ECC that the images are programmed with?

    4. What does your U-Boot environment look like?

    Thanks, for your reply. I have successfully booted Android through SD card,. Sorry,I don't remember the answer for above questions, I'm new to this platform. Please provide me steps to boot through NAND memory and how to transfer data through serial com port from pc to AM3517 development board. I have installed windows 8.1 and ubuntu 10.04 in virtual box. Is there any drivers need to install?

    Thanks in advance.
