RE: 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 ram



First 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.b fe000000 00000000 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.b fe000000 00000000 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
