For test purpose I got the last eCos snapshot with port for Atmel AT91 CPUs 
and Atmel's EB01 evaluation board.
I make a simple test example - the spurious interrupt is generated every 
time when the timer interrupt appear.

Which options from "ROM monitor support" (in eCos configuration tool) must 
be activated to work the target with JEENI (or BDI2000) without ROM monitor?
When all option in "ROM monitor support" are deactivated the program 
crashed in hal_if_diag_init() (in hal_if.c) by 
CYGACC_CALL_IF_SET_CONSOLE_COMM macro - the virtual vector table is not 
initialized maybe.
My test example work only if I activate "Initialize whole of virtual table".

Do I need virtual vector table to debug with JEENI without ROM monitor?
Why is the spurious interrupt generated?

best regards
Ilko
