3.2 PC Host Example

The PC as host need a software GUI (MSPM0_BSL_GUI.exe or Uniflash) and a USB-to-UART bridge. Two hardware bridges are included (can be chosen in the MSPM0_BSL_GUI.exe): one is XDS110 on the MSPM0 LaunchPad kit and the other is a standalone XDS110. Both of the bridges support the backchannel UART that can be used as a USB-to-UART bridge. The XDS110 on the LaunchPad kit supports NRST pin and BSL invoke pin controlling that can be used by the GUI to start BSL mode on the MCU. For the standalone XDS110, two GPIO output pins (IOOUT0 and IOOUT1) in the AUX connection port can be used to control the NRST pin and BSL invoke pin on the target device and start BSL mode. (This is implemented with MSPM0_BSL_GUI.exe).
