Hi to all, as suggest to me by tcomins I insert this line in the open ocd cmd file:
flash bank lpc2000 0x00000000 0x20000 0 0 0 lpc2000_v2 14746 calc_checksum

and then i insert this lines in the gdb commmand tad inside eclipse:
target remote localhost:3333
monitor reset halt
monitor sleep 500
monitor poll
monitor soft_reset_halt
load
break main
continue
info breakpoints
but I'm not able to enter in debug mode, and these are messages present in the eclipse console tab:
