This means you are running your test program from either an IDE hard
disk or a CompactFlash card. Am I right?
No the test program is located in flash memory.
Bah. Probably same well-known cache aliasing issue with non-DMA block
transfers.
There were contentious patches moving around to fix this issue. But I
dont know what happened to them. Just search for
"cachepolicy=writethrough" in the mailing list archive for more details.
But in your case youre using the mtdblock module (hint: JFFS2 would be
much more advantageous) and it probably lacks the necessary cache flush
call.
