Programming the first CORE (ARM9) works well. Programming the second core (NXP LPC246) fails with the following messages:
----------------------------------
Connecting ...
- Connecting via USB to J-Link device 0
- J-Link firmware: V1.20 (J-Link ARM V6 compiled Oct 15 2008 10:48:36)
- JTAG speed: 5 kHz (Fixed)
- Initializing CPU core (Init sequence) ...
- Initialized successfully
- JTAG speed: 5 kHz (Fixed)
- ERROR: Verification of RAMCode for CPU clock frequency detection failed!
- ERROR: Failed to measure CPU clock frequency
- ERROR: Failed to connect
----------------------------------

Any Ideas ?
