Go to the LEDMCUEVM-132 (PSIL-132) and locate J15 and RESET_SW1. Install shorting jumper at J15 locations as seen and then press the RESET_SW1 as seen in Figure 5-23. This action places the MCU in Bootloader mode.

Click Yes > to re-launch GUI.

A window appears indicating the the LEDMCUEVM-132 must be changed from bootloader mode to normal mode. This is accomplished by removing the shorting jumper from J15 then pressing the "RESET_SW1" switch and wait 3 seconds to ensure device drivers reload, see Figure 5-26.
