[ECOS] RE: eCos ROM application crashes without Redboot

I found the problem. 

It is not in eCos, but a lack of proper understanding of 
the JTAG debugger yours truly is using. 

When I connect to my target using GDB and issue a reset command,
the JTAG debugger (BDI 2000 from Abatron) will poke lots of
registers(because I told it to in the config files) to set up e.g.
memory layout, etc. 

I.e., this GDB command sequence crashes:

(gdb) monitor reset
(gdb) continue

This does not:

(gdb) monitor reset
(gdb) jump *0x1000000
