Hi,

      I just bought a QN9020 MiniDK board. According to the documentation AN11664, I can download the sample application to the chip by QN902xISPStudio, and it works fine.  And then I try to download the application code to board by J-Link in KEIL IDE.  The IDE's build output tells me that the download was successful, Meanwhile, the development board is not working properly:

      >LED1 and LED2 are not bright.

      >I tried using RESET button, or button1 or button2, but I didn't get any response.

 

 

Thanks for your help!
