When using j-link to download programs or debug online, there are two modes: JTAG and SWD
You can choose in Keil:
The following are the interface pins used in the two modes:
It is recommended to use SWD mode because it saves pins and the debugging function is not affected.
In SWD mode, only 4 IO ports are actually needed, including downloading programs and online debugging.
They are: PA13/JTMS/SWDIO, PA14/JTCK/SWCLK, VCC, GND
