That's a good point.  We may have to write our own driver instead.

Thanks for the tip.  I was looking at the toolchain building 
instructions, and also saw this discussion:

http://sourceware.org/ml/ecos-discuss/2008-09/msg00040.html

So I guess I'll try to use the CodeSourcery 2008q3-39 ARM EABI, and 
compile the latest newlib (v1.16.0) and GDB with that.  Should be fun. 
I'll make a point to keep some notes on the process, and post anything 
useful to the list.

Best regards,

James
