I have the LPC824 and am trying to debug it using an lpcxpresso v2 board which has a LPC1549 on via SWD. I'm using the LPCxpresso IDE

Currently I am having no joy so far. This is my error:

""Error in final launch sequence
  Failed to execute MI command:
-target-select extended-remote | crt_emu_cm_redlink -msg-port=60254 -g -mi -2 -pLPC824 -vendor=NXP -vc -reset= -ProbeHandle=1 -CoreIndex=0 -flash-driver=LPC800_32.cfx
Error message from debugger back end:
Remote communication error.  Target disconnected.: No error.
  Remote communication error.  Target disconnected.: No error.""

Just for starters I'm using the periph_blinky to see if I can debug anything on the chip.

I believe I have followed the instructions in the datasheet, user guide and these links:

(see piccy attached)

I have configured my pcb to match what's in the datasheet and I have a pull up on pio0_12 which is the ISP entry (see piccy attatched), I have alos configured the V2 board to have J1 shorted, and J2 shorted on pins 2 & 3.

Please tell me where I have gone wrong.

Thank you.
