I’ve recently compiled OpenOCD SVN121 (been using SVN62 for a long while now!). My target is a LPC2214 & JTAG interface is FT2232. I’m having problems when I run the reset command via telnet. The OpenOCD output after issung the reset is:

When I revert back to SVN62 with exactly the same hardware setup everything is fine. Has anything changed with the config which might explain the difference ?
Thanks
