G'Day,
I've been looking at a few of the posts regarding debugging tools, and the standard answer on this list appears to be "Get a BDI2000". I'm presently looking at getting a debugger to use to bring up a new board, get U-Boot going, and eventually do a lot of OS work (a new OS that we're developing - see http://www.ertos.nicta.com.au -- sorry, shameless plug).
Some people that we are working with use the Lauterbach Trace32 tools extensively, and we've had some good experiences with them. I was wondering if anyone on this list had used both (particularly while developing U-Boot), and how the BDI-2000 stacks up against the Lauterbach equivalent. (Apart from being significantly cheaper).
Pros: BDI - 10Mbit eth, Lauterbach - 100 Mbit. Lauterbach scalable and simply extendable, BDI - not. Cons: BDI support gnu toolchain natively (in GDB server mode), Lauterbach - not (sometime it parsing elf/dwarf correctly, sometime, usually in critical cases :), not). And you are know, hmm, strange Lauterbach price policy: price of BDI firmware for a new CPU target is approx. 1000 eur, for the Lauterbach - price of new device.
Any insights much appreciated.
Many thanks,
