Subject: CRC errors and DMA

Message-ID: <200408131855.16376.lucasvr@gobolinux.org> (raw)
Hi,
What happens when the processor tryies to read data from memory while the bus
is being used for DMA transfers by another device? Is it possible that this
kind of situation turns into CRC errors when trying to read data from a flash
device (JFFS2)?
Given that this problem can happen, is there a way to make JFFS2, or the MTD
subsystem to try to execute the operation again?
Any suggestion is very welcome.
Thanks in advance,
Lucas
