Thanks for giving notice.

I do have a working JTAG adapter (with openocd). So it *might* be 
simpler, although I don't know yet all the details of the memory layout 
(nor how to define it for the compilation of the program), and of course 
I don't know how the eCos startup sequence works etc.

I'm currently trying to get FreeRTOS running (which isn't exactly as 
easy as advertised either if you don't have Windows and the IAR tools 
since the Demo is assuming those), I'll take whichever route gives me 
light at the end of the tunnel first. It seems I have to delve into the 
thumb vs. 32bit code transition/linking business and linking etc stuff 
anyway by myself.

Christian.
