I got a LPCXpresso with LPC1769 rev b target. I've installed the latest  Code Red IDE (4.2.2) on Fedora 16 running on a physical machine. I can  build examples for LPC1700 fine but when I try to debug any of them, IDE  freezes.   When I connect board to usb port, I can see a flashing led and lsusb  says: 

  Bus 001 Device 004: ID 0471:df55 Philips (or NXP) LPCXpresso LPC-Link 

Then when I start IDE, a select Debug for some of the demos, it builds,  displays a dialog saying "Initializing LPC Link", dialog closes and on  the status bar I can see "Launching adc_buzzer. Debug (57%)"   and led on board stops flashing. IDE freezes at that point.  lsusb now says:

  Bus 001 Device 005: ID 1fc9:0009 NXP Semiconductors  

The IDE has spawned the following proceeses (seen while it is hanging):

3130 pts/0    Sl+    0:12  |   \_  /usr/local/lpcxpresso_4.2.2_238/lpcxpresso/lpcxpresso 
3431 pts/0    S      0:00  |       \_ arm-none-eabi-gdb -q -nw -i mi  /home/adk/workspace/adc_buzzer/Debug/adc_buzzer.axf 
3443 ?        Ss     0:00  |           \_ crt_emu_cm3_nxp -g -mi -2  -pLPC1768 -vendor=NXP -wire=winUSB -msg-port=52073
When I kill the IDE and reconnect the board, led starts flashing again. 

Any ideas?
