Hi all,
I found a problem with load command on ARM based board. When I load hello_world standalone application using filesystem load command, the u-boot crashes. Loading with loads is OK.
I think that the problem is caused by cache inconsistency. If I add calling the flush_cache function, problem is solved.

I also ran into cache inconsistency problems when copying the stand
alone from NOR flash to RAM. I was using Freescale 85xx SOC.
Based on a few email conversations I had at the time, I added
http://www.denx.de/wiki/view/DULG/UBootStandalone#Section_5.12.3.
Maybe you will find something useful.
