I am using LPC11U68 eval board to program and debug a off board target processor (LPC11U68).

The debug session does not start and I get the following errors:

MCUXpresso IDE RedlinkMulti Driver v10.2 (Jul 25 2018 11:25:37 - crt_emu_cm_redlink build 555)
Reconnected to existing link server
Connecting to probe 1 core 0:0 (using server started externally) gave 'Ee(42). Could not connect to core.'
Connecting to probe 1 core 0:0 (using server started externally) gave 'Ee(42). Could not connect to core.'
Connecting to probe 1 core 0:0 (using server started externally) gave 'Ee(42). Could not connect to core.'
Server OK but no connection to probe 1 core 0:0 (after 3 attempts) - Ee(42). Could not connect to core.
Failed on connect: Ee(42). Could not connect to core.
No connection to chip's debug port

I saw similar postings but the suggested solutions did not work for me.

The debugger configuration is shown below:

Is there a known solution to this problem?

Thanks!
