Hi Jack,

I believe that driver has only been tested with the FT232AM, which has not been manufactured for several years now. Ashley (cc’d) implemented it as an intern project in 2013: https://github.com/tianocore/edk2/commit/3f1484f

There probably needs to be some work done to get it running with newer FTDI chips like the FT232RL.

Thanks,

Nate

Hi,

Are there any known bugs with [edk2-stable202002] when using the FtdiUsbSerialDxe driver? I am seeing errors during initialization when TerminalDriverBindingStart() tries to reset the FTDI device and gets EFI_DEVICE_ERROR.

Thanks,

Jack
