Thanks greatly for creating the GNU tool OpenOCD!
I followed the tutorial on this website to configure my LPC2210
(flashless) board. http://www.yagarto.de/howto/yagarto1/index.html
However, when I tried to configure the wiggler JTAG, which connected the
PC with the LPC2210 board via a parallel port, it failed. It said:"
Info: openocd.c:82 main(): Open On-Chip Debuger (2006-08-17 17:00 CEST)
Debug: jtag.c:1184 jtag_init():
Debug: parport.c372 parport_init(): requesting privileges for parallel
port 0x378…
Error: parport.c:380 parport_init():missing privileges for direct i/o
Could anyone tell me what the problem is? And anyone who is experienced
in configuring a system with external flash, please give me some
tutorials. Thank you very much.
The configuration file is as follows:
