LPC845: Error:Wire ack fault - target connected?

[farha]

I am using LPC845 . From debugging and programming image using LPC-Link 2 debug probe. I have installed MCUxpresso IDE v11.5.1_7266 to connect with the board via LPC-Link 2.

I couldn't able to flash to board. I can see below the error every time.

Error: Wire Ack Fault - target connected?

Same error. Over two LPC55S69 boards... I'm at my wits end.

[ErichStyger]

I would check first the wire/connection: maybe you have it connected with wrong orientation?

Are you using your custom board or a LPC845-BRK board?

[farha]

I am using  custom board.

I have shared wire/connection.

kindly check attachment.

[ErichStyger]

I mean that you check the connection/soldering on your board.

[farha]

I have checked , it is ok.

[ErichStyger]

Have you tried another debug probe, e.g. a J-Link or P&E Multilink?

Check the Vddsense pin on the SWD header: does it have 3.3V or Vdd on it?

Are you able to debug other boards with your probe with the same MCU?

Have you tried deleting the .launch and recreated it?

Other than that: I wrote a checklist here:

I hope this helps,
