There are debuggers that range form $50 to $50k with no JTAG standard. $50 wigglers that are painfully slow because they bit-bang the parallel port and $50k Gigabit interface with GBs of fast memory that can "capture bugs" in realtime (that is if you can define/setup the trigger condition to capture "the bug", but for a 400MHz processor that may only mean 1-2 seconds of data). The BDI is a nice product for $2k, wish I would of thought of designing it. You can either communicate with it directly for single step, breakpointing, etc, but the coolness is the capability to run remote gdb, then there is insight which is a gui that runs ontop of gdb.... works great debugging u-boot and kernel/user code later....but the best part is no need for windose and with DENX you don't have to pay big $ to metrowerks, greenhills or the like and wait while they develop or if they will ever develop debugger software for your target!
