Hi, Kim,
I have tried to download code to flash based on MC56F84789 based on usbtap device, no problem. I copy my log.
Regarding your issue, from the log, it appears that the multilink universal device has issue from the error message "Unknown Fault. The Debugger can not connect to the P&E device(GDI Procotol fatal error:)".
can you use usbtap device and have a try?
secondly, can you download the *.elf file to flash with the CW for mcu ver11.c tools itself by clicking Run->Debug Configuration....?
Can you see the Multilink Universal device icon in Device Manager on PC?
Hope it can help you
