@"The FTDI drivers for the JTAG-SMT3 automatically download and enumerate as a virtual com port that can be used with standard OS's." I don''t know what do You mean by "standard OS" I have W10 1903 and only what i see is: Enhanced com port and Standard com port. Both doesn't work. Windows update can't find correct drivers. Driver provider, date, version: not available. Should we simple download FTDI drivers from FTDI.com website? For linux I had to run driver installation script from vivado drivers folders, otherwise it didnt work for me.
