[U-Boot] How to test a new u-boot image over network?

[vikas.sontakke at emc.com]

Hi Wolfgang,

Thank you for that reply!  

I do know that the board has NAND flash and it is seen by the u-boot.  

FLASH: 16 MB
NAND:  1024 MiB

The vendor has told us that the actual flash is lot bigger than reported by u-boot.

> (assuming your out-of-tree port supports NAND booting)

How do I find this out?

Thanks,
- Vikas

You cannot run the image without buring it to flash.

Did you bother to read the FAQ?  The very first U-Boot FAQ handles
your situation:

You may be able to istall a NAND booting version of U-Boot to NAND
flash (assuming your out-of-tree port supports NAND booting).

Once you got this working, you have a recovery system, and you can
erase and re-program the NOR flash without risk.

Best regards,
