Yes, I suppose it does. > I'm using Spansion MirrorBit S29GL128N, which reads at about 0.6 MByte/s. I think you should get more like an order of magnitude higher....

Depends on how you are measuring it. You ought to be able to get at least 2 orders of magnitude higher read speeds with a good sync Flash. Some of the newer stuff is even faster. -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
