about filesize when copy from flash to ram

You are copying flash over top of your interrupt vectors, overwriting active code and crashing your system. Don't do that. Getting a load into the bottom of RAM (e.g. loading linux) is a delicate dance that u-boot does well, so use that function. You are not going to be able to do it with the "cp" command. Read the README file for a lot more information.

Subject: about filesize when copy from flash to ramFirst thank you for your help.
Useing my MBX860 board's u-boot,I try to copy some files from flash to ram.The files in this address "
fe600000" in the flash.
I find a problem when I use this command"cp.bfe00000000000000 filesize",if the filesize<=900sbit(hex),the
file can copy from flash to ram.but if the filesize>=900sbit(hex),the system will reset.e.g."cp.bfe00000000000000 1000"will reset the system and fail to copy to ram,why?

The critical value of filesize is between 900~1000,about 2Kbytes,why?
Thank you
