When dealing with USB drivers, Apple is even stricter if the USB device has any of the FTDI VID:PID pairs, macOS assumes it should be associated with a virtual UART device, and there is no simple way to reconfigure this. As with usual drivers, this generated driver can be installed and uninstalled, if no longer needed.Īn older workaround used a tool called Zadig, but this tool had the major disadvantage that changes were permanent, and it was not possible to return the FTDI device to the default UART. One possible solution is libusbk, which also comes with a tool to generate these drivers. This requires installing a special driver, specifically configured for a given VID:PID. Windows allows a port to be acceed via the user-space WinUSB driver only after explicitly reconfiguring a specific interface for direct drivers. On the HiFive1 board the problem is complicated by the fact that the second FTDI interface is used to forward the trace stream and must remain a virtual UART.Įxcept on GNU/Linux, where direct access to USB devices is native, for Windows and macOS there is no elegant solution to this problem, but only some work-arounds. ![]() The FTDI chip can be reconfigured to access the JTAG interface via direct drivers, but this requires the presence of a small EEPROM to store the configuration, and neither board has this EEPROM physically installed. Both the HiFive1 and the Arty boards use FTDI to access the JTAG interface.īy default, the standard FTDI drivers available on Windows and macOS assume the FTDI chip is used to connect UART ports via USB.
