It's my understanding that the jtag interface is only needed if you screw up the flash enough that the boot loader is messed up. Even if the OS itself won't boot, the bootloader can tftp stuff and write to flash. What I plan to do is bet the OS running over NFSROOT (which is about working now), then create the ubifs image and write that from the running linux system to the mtd root partition area. Certainly you can reflash the kernel from any running plug OS. I did that on my older sheevas to upgrade to 2.6.32 while keeping the stock ubuntu OS. I must admit that I a but confused about their jtag device too. It's always been my understanding that the mini USB port was both a serial console and a jtag interface. I'm not really sure; probably best to ask the plugcomputer.org forum. They have lots of info on reflashing the plugs and so forth. I plan to order mine without the jtag. Haven't had any need for jtag with my plugs yet. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
