Hi All,

I have issue with debugging using QN9090 dev kit. Most time when I start debug it can't find the hardware:

Some LEDs flash and above popup is displayed.

The only thing I can do is disconnect from PC or randomly press RESET and ISP buttons on board and sometimes it allows to run.Most times not.

When it finally runs, debugger disconnects after a few minutes, and can't change breakpoints. Tried adding one and got this message:

This befaviour is from new one.

Can anyone point to possible solution. Maybe it is faulty.

Thanks

Mike

Hello,

 

I see that you are building the temperature sensor example and you are working on this, by any  chance, did you disable the low power configuration on the example ? Whenever you are using an example with the low power capabilities enabled you will lost the debugger functionality as it disable the pins in order to save power.

 

Could you please check the definition state of cPWR_UsePowerDownMode?

 

regards,

Estephania

Hi Estephania,

Thank you for help, but it didn't work..

Another observation. When I manage to start, when i click STOP icon, I have the error reported by target message (the second one in my first message).

And I am able to run much more often after pressing ISP and then RESET.

Is there anything else I can do?

Regards

Mike
