Dear Jim,
Thank you very much.
I read the Wiki page. I was running to load the standalone application program. CPU is so ARM, there is instruction and data caches.
As in the Wiki of example, a program that was loaded with 'loads' command was able to run. However, when I loaded in the same program the 'fatload' command, it could not be executed.
When I look at the source program, in the 'loads' command has been executed cache flush. But, in the 'fatload' command, cache flash was not executed.
So, I created this patch.
Thanks.

The wiki includes information about cache considerations for the "go" command [1]. If possible, please check that information to be sure it remains consistent with this patch.
Thanks, Jim
