Lpc2000

Thank Dominic, I heard that first I could write my program to the on-
chip RAM via ISP, then I could used the pre-downloaded program to 
download my bootloader to flash if the program running in RAM is a 
flash program. Is it that possible? Is there anyone doing this 
before, and will it be very difficult? Another question is where can 
I download openOCD?
 
Best Regards
