Hello team,

I have been working with QN9080 a few weeks back and everything was working properly, but when I have tried to work with the devkit once again and I got the following error: 'Wire Ack Fault'.

Could you please advise how to overcome this issue, please find below the errors log.

Hi Shai,

 

Could you please let me know which SDK example are you programming to your boards?

Also, could you please check to see if the following macro definition is set to 0?:

/* Enable/Disable PowerDown functionality in PwrLib */
#define cPWR_UsePowerDownMode           0

After programming the device in ISP mode, the shorted JP15 must be removed and the device reset to allow it to enter the normal execution mode.

 

Please let me know if you need any more information.

 

Best regards,

Sebastian

Hi Shai, I hope you're doing well!

 

Could you please try programming your QN9080-DK in ISP mode?

 

You can enter this mode by pressing the reset button while the JP15 jumper is shorted. After programming, you can remove the jumper and reset the board again, and the device should be programmable again.

 

This could be happening because the program you downloaded may have implemented Low-Power mode, and it may have disabled the SWD interface. To prevent this, some SDK examples have the following macro, which can be set to 0 to disable low power mode for debugging purposes:

/* Enable/Disable PowerDown functionality in PwrLib */
#define cPWR_UsePowerDownMode           0

 

Please let me know if you have any further issues programming your board.

 

Best regards,

Sebastian

Hello Sebastian,

I have tried to flash via ISP mode and it works but once I have been tried to debugging I got an error.

Hi Sebastian,

I did the procedure again after reinstalling MCUXpresso, and now it works as expected.

Thanks a lot for your time and effort.

BTW, my QN908X SDK version is 2.2.1 and the cPWR_UsePowerDownMode, MACRO I did not found where is the macro list in settings are but I have noticed in the code the that

#if defined(cPWR_UsePowerDownMode) && (cPWR_UsePowerDownMode)


is marked in gray which means is Disable ('0').

Thanks and stay safe,

Shai

Have you tried to boot it into ISP mode and then re-flash with the debugger?
