Wire ACK Fault in DAP access

saad_saeed — Wed, 09 Jan 2019 14:02:40 GMT

Hello,

I have just recently installed McuExpresso 10.3.0. Previously I was using McuExpresso 10.0.2. When I downloaded the latest SDK for FRDM K64 and tried to debug a demo example, I got this error.

Failed on connect: Nn(05). Wire ACK Fault in DAP access

I dont understand what is wrong. Kindly, help me with this.

Thanks,

Saad.

Hi Saad,

First, we need identify this issue is only on one project or a common issue for all project.

- please create a NEW project in a NEW workspace, see how the connection works.

- please test your project in a NEW workspace, how does it work?

If both of above can't fix the issue, I suggest you update your K64 firmware.

OpenSDA Serial and Debug Adapter|NXP

Have a great day,
Jun Zhang

I found the problem was that the MCP was locked, It's a simple way of unlocking a MCU in MCUXpresso that I thought I'd share with other novices so they can get going again easily:

Step 1: Open the GUI Flash tool

Step 2: Choose Resurrect locked...

Step 3: Hit Run.

In a moment the MCU will be unlocked and ready for more programming action!

@CBI Did you manage to find the solution for this? I am facing the same problem and tried the same solution but it is not working for me as well

In mcuxpressoide-11.7.1_9221 there is no such thing as "Resurrect locked ..."

Re: Wire ACK Fault in DAP access

As the screenshot indicates:

"Resurrect locked Kinetis device": this feature exists for Kinetis devices only.

If you happen to have an LPC: try erasing the flash from the bootloader, or you might use a recover script like described here: https://mcuoneclipse.com/2023/07/25/linkserver-scripting-and-how-to-recover-mcus-with-a-script/

Tried the script....no dice. But thanks for pointing me in that direction.

Thanks for trying. It worked in several cases on my side. Maybe indeed your device is permanently bricked.
