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!
