Could you please try with an ISP reset. Please check the following link:

I alrerady tried:

- Window > Preferences > LPCXpresso > Redlink Options > Pull ISP on reset

(on LPC-Link 2

- power board, press isp button then press rst button, release rst button

- also tried

1. GND the ISP pin

2. With ISP still pulled to GND, assert RST and release RST

3. Now remove the GND to ISP pin, and start your debug session

still nothing...
