What is your target board? Is it custom or an LPCXpresso board?
"Target marked as not debuggable" normally means one of:
- the SWD cable is not correctly inserted, or is broken
- the target has been put into one of the CRP modes - you may only be able to recover this using FlashMagic over a UART
- the board is not provided with power
- the debug circuit is incorrectly designed
