Thanks, Shawn! I'm not much up on the mtd stuff (read: while I understand all of the words and most of the syntax, the "cmdline" part of your reply is still greek to me). Is there a good reference I could read on how it works and interacts between Uboot and Linux? Failing that, could you give me an explanation of what your cmdline stuff does and why it's needed?
