Getting the same problem and I have selected the board as the UNO. After installing the FTDI driver I have a COM1 port that only shows up when the microview is plugged in so I don’t think its one of those two problems. My error looks like
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xae
