IMXRT1050 EVKB Wire Ack Fault

[kwolley]

I appear to have a similar problem to a few others however solutions provided are not working for my situation.

Up until a few days ago, I was able to debug my 1050 evkb without fail.  I started a new project and the Wire Ack Fault error started to appear.  Troubleshooting efforts so far:

1. attempt to debug previously working project - fail
2. create new workspace, create hello world from SDK - fail
3. uninstall MCUXpresso and JLINK -> restart -> reinstall - fail
4. https://community.nxp.com/t5/LPC-Microcontrollers/LPC54628-Error-Wire-ack-fault-target-connected/td-...
5. https://community.nxp.com/t5/MCUXpresso-IDE/MIMXRT-1060-EVKB-cannot-debug-anymore/m-p/1472056#M8163

I am operating on MCUXpresso version 11.5.1 and SDK 2.11.1.

Board connected to computer via J28:

Stream of events are as follows.  Error logs attached.

Any help is greatly appreciated.

Hi @kwolley ,

  Don't worry, it's easy to recover, you just need to do the external memory erase at first in the serial download mode, normally, your issue is caused by the flash is downloaded with the abnormal code, then it will also cause the debug issues.

  Follow me now!

  1. board enter the serial download mode

     Power off the board, SW7:1-OFF,2-ON,3-OFF,4-ON

    Power on the board

  2. Find another USB cable, connect to J9

  3. Use the MCUbootUtility to connect your board, and do the mass erase.

About the MCUbootUtility, you can download it from this link:

https://github.com/JayHeng/NXP-MCUBootUtility/releases/tag/v3.5.0
the related user manual is:
https://github.com/JayHeng/NXP-MCUBootUtility

4. After the mass erase finished, then you can power off the board, and change the 

SW7:1-OFF,2-ON,3-ON,4-OFF

Then, use the MCUXpresso IDE project try to connect the board again with CMSIS DAP if you don't change the on board debugger, it should be OK.

You can check this picture to check which on board debugger you are using now:

Control Panel\Hardware and Sound\Devices and Printers

Please try it on your side, any updated information, please kindly let me know.

Best Regards,

Kerry

Thank you for getting back to me.  The board does not recognize a device is connected.

However it appears in the device manager:

Current board setup:

• SW7: 1-off, 2-on, 3-off, 4-on
• J1: Jumper 3&4
• J9 to power
• J28 to computer

What am I missing?

Thank you for your help. The solution in my case was to do the following:

• power off the board
• Enter Serial Programmer by setting SW-7 to 1-Off, 2-On, 3-Off, 4-On
• Set J1 to Jumper 3&4
• Connect J28 to computer
• ConnectJ9 to power
• Use MCUXpresso to erase flash using LinkServer (see below)

• Power down the device
• Set SW-7 to 1-Off, 2-On, 3-On, 4-Off
• Connect J28 to computer
• ConnectJ9 to power
• install LED blinky from SDK demo
• debug as CMSIS-DAP

Marking this solution as solved.

Hello @kwolley @kerryzhou ,

I have the same problem but with a different EVB (FRDM-KW38). Do you know what steps I need to take for this board?

Any hint/help is much appreciated.

Cheers,

Nader
