不能运行示例项目

Hi,

I have some basic problem with my setup and need your guidance. On my Expert Kit, when I compile and run the Blinky project, everything works as expected. All the other example projects (as I see it using the BLE part of the chip) will not even run to main_func, but ending up stuck in some interrupt handler or even Hardfault_Handler. What could be the problem?
Note: It is the DSPS i need in the end, I just tried the other projects in hope of finding a clue to the problem.

Details:

Hardware: Development Kit Expert, rev C2, with DA14580_CB_PX1_QFN48_078-13-A daughterboard
The dev kit is configured as in figure 9 in UM-B-014_DA14580_518 Bluetooth Smart Development Kit - Expert_v1.5.pdf

PC:HP DC7800 "standard PC" with Windows 7 32-bit

Keil: v4.74.0.22

Results:
Blinky_20150501.zip:
Compiles and runs exactly as expected, no errors or strange things. Can be stepped and debugged. Led blinks :P

DA14580_dialogBeacon_3.40.6.zip:
Compiles and runs, but does not bring up a visible BLE beacon. Does not reach main_func. If I single step through the code, disassembly window takes me through
- 0x200004A0 LDR R0, =SystemInit
- 0x200004A4 LDR R0, =__main
- 0x200004A6 NMI_Handler PROC BX R0
and then I get stuck at
- 0x000000E6

DA14580_DSPS_3.150.2__13_2_2015.zip:
Compiles and runs, but does not bring up any visible Bluetooth device. When singlestepping it does exactly like the DA14580_dialogBeacon_3.40.6.zip does. Both this one and the beacon needs to exit debug session to get out of the 0x00000xxx address range, clicking RESET wont help. I checked the code and the UART input pins (RX and CTS) are configured as INPUT_PULLUP.

DA14580_REMOTE_BLE_IR_3.80.4.zip:
Like the above

DA14580_TAG_3.20.6.zip:
Compiles, but reports No Cortex_M device found in JTAG chain. NOTE: If i run the Beacon project above again after this one, it works the same, so the Cortex device IS there...

DA14580_SmartDice.zip:
Compiles, but reports No Cortex_M device found in JTAG chain. NOTE: If i run the Beacon project above again after this one, it works the same, so the Cortex device IS there...
