Need to use J-link emulator and Keil4 MCU development tool, the operation steps are as follows:

1) Connect the emulator to the JTAG interface of the mother board (note that the raised part of the emulator cable interface in Figure 1 is aligned with the JTAG interface), and the other end is connected to the computer's USB port.

2. SWD download

Need to use ST-link emulator and Keil4 MCU development tool, the operation steps are as follows:

As shown in Figure 6, the development board reserves a four-wire SWD interface, which can be connected to the corresponding interface of the emulator through a DuPont line to connect the emulator to the computer.
