Hello there
The QN9020DK development kit uses SWD mode to download the program. Has not been successful. Although KEIL can recognize SWD (as shown in Figure 1 below). However, a warning will be reported during the download process (as shown in Figure 2 below). An error will be reported (as shown in Figure 2, Figure 3 and Figure 4 below).
Use Jlink to connect the page as shown in Figure 5.
Can you help me solve this problem?
Thank you!

Hi,
It seems that your device is in sleep mode.
Could you please press the button 1 before you try to program your device again?
Regards,
