JLink mini DK board QN8020 connection failure

[tonymakkiel]

Hi,

       Is there anything I need to do to establish JLink connection with the DK board? Attached is a screenshot of the error I get.

I have not changed the jumper settings. At present 

J11 connected 2 and 3

J12  connected 1 and 2

J13  connected 1 and 2

Hi Tony,

No, you do not need anything else.

Could you please press the reset button when you try to connect the device?

Also, press button 1 to wake up the device.

Regards,

Mario

Thank you Mario. That worked. On more quick question, please. What is the difference between "9020 D9M8K" and "9020 105PJ" ?

I found those numbers written on the QN9020 chips. So am guessing they are different versions of the same chip. But am wondering what are the difference?

Hi Tony,

That numbers are the lote number and also the date that was made.
