After flashing the "MSP432E4 Flash Based USB DFU Boot Loader Example" output file to the 432 device I then put the 432 into bootloader mode by cycling power after grounding pin PJ0 to ground. Once in bootloader mode I then flash usb_serial_device_MSP_EXP432E401Y_tirtos_ccs.txt over USB using BSL-scripter and I get the following result.

REBOOT_RESET
Once flashed I reset power and the 432 fails to show up in device manager under ports with a valid com assignment and I can no longer find DFU. To get the part functional again I must erase the device using Uniflash. The only changes I've made to the usb_serial_device_MSP_EXP432E401Y_tirtos_ccs example are below. What am I missing? Thanks!
