problem: wire ack fault - target connected?

[yvzblgcyln]

Hi, i have a problem which says "wire ack fault - target connected?" while debuging. Is there any suggestion to solve it?

I am using LPC-Link 2 and CLEV6630A board. That issue occurs when i try to debug "NfcrdlibEx4_MIFAREClassic" example which published by NXP itselfs.

Tnx for now, have good day y'all.

Hi @yvzblgcyln :

CLEV6630A evaluation board needs to be connected to the computer via LPC-Link2, as shown  below.

Please also check the LPC firmware and driver.  you can refer to chapter 3 in AN11022:  CLRC663 Evaluation board quick start guide.

Thanks for your reply, my connection looks similar as in picture. I also checked quick start guide, there is nothing i didn't do.

Hi @yvzblgcyln ：

please check the device manager of your pc, there should have a J-link driver.

If this J-link driver exists, please use jlink commands to check this connection is successful, please refer to  below picture.

Hi, there is a J-link driver in device manager as you sent. Then i checked my connection, at the end of process J-Link commender said "Cannot connect to target". What am i suppose to do?

I don't know why but i do not have permission to upload images. Here is my J-Link commender script's output:

Hi

I would suggest you change another j-link or LPC link,   or try this lpc-link with another board.

Did you rework this board?  for example ,remove some components from this board? Did this board work before?

Hi, this card was working 2 mounths ago. My coworker was working on it, and last time he gave it, i guess it was working. I just connected cables (LPC-Link:J7 to CLEV6630A and other USB cables), i didn't change anything on it. Also i have just one LPC-Link and one board.

Hi

I would suggest you check the power supply. make sure the jumpers are in the right places according to the quick start guider.

J-link is in the right direction.
