I just picked up a set of Lego Mindstorms NXT 2.0. It’s a robotics kit based on the AT91SAM7S256, which is a rather nice ARM7TDMI based SoC.

Coincidentally, the little kernel (lk), written by Travis Geiselbrecht and being used as a bootloader for Android and webOS, supports AT91* platforms. Of course, this means I have to get lk running on the NXT.

I recently discovered a really cool tool called IDA Pro. It’s an interactive disassembler with some powerful features that make examining low-level code and debugging very easy.

I’m currently working on getting IDA Pro to talk to my Lauterbach JTAG Debugger via GDB Remote Serial Protocol, but it seems that there is a bug in the Lauterbach software. The two products should make a very powerful combination.
