I think you should get more like an order of magnitude higher.... Get an expert to look at your timings in the bootloader.

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 majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
