Hi All：
        I use LPC-link 2 as a debugger to debug LPC1768, the IDE I use is LPCXpresso v6.1.4_194,
when I debug a project, the IDE have following problem:

[color=#930][color=#900]       Error in final launch sequence
        Error: Unable to connect wire for probe index 1.
        RedlinkAPI: Wire Ack Fault - target connected?

[color=#930]      Redlink Server will be restarted.
      Please restart your debug session.
      Error: Unable to connect wire for probe index 1.
      RedlinkAPI: Wire Ack Fault - target connected?[/color]
[color=#930]
      Redlink Server will be restarted.
      Please restart your debug session.[/b][/color][/color]
[/color]

I need help, thanks.

Few things to try…

Turn the power to the board and the probe off, then try booting your board into ISP mode before starting your debug connection:

Ensure you have shut down any previous debug session. You must close a debug session (press the Red 'terminate' button) before starting another debug session. It is possible that the debug driver is still running in the background. Use the task manager or equivalent to kill any tasks called:
[list]
[*]redlinkserv
[*]arm-none-eabi_gdb*
[/list]

Try a different USB cable!

Try a different USB port. If your host has USB3 and USB2, then try a USB2 port. There are know issues generally with motherboard USB3 firmware, ensure your host is using the latest driver from the manufacturer. Note: this is not referencing the host OS driver but the motherboard firmware of the USB port.

If using a USB hub, make sure it is a powered one. And also try a direct connection between the LPC-Link2 and the host computer instead.

Regards,

Yes, Because paste of the chip, LPC-Link2 has no problem.[/quote]

Hello Zhai.
I am having the exact same problem on my EA-OEM-509 (LPC1788-32 developer's kit).
I was able to debug projects for a few days using LPC-Link2 before the same error as yours appears.

Redlink Server will be restarted.
Please restart your debug session.
Error: Unable to connect wire for probe index 1.
RedlinkAPI: Wire Ack Fault - target connected?

May I know what you meant by paste of the chip and how you resolved the problem?
Thanks in advance.

This means that LPC-Link2 is unable to find your target over JTAG/SWD.
- is the target connected?
- is JTAG or SWD correctly wired up?
- is the target powered?
- has the target entered a CRP mode?
-
For more information, search the FAQs for Debug Connection.

First, there is no problem, I can debug project.
After a period of time this problem appears.
