Guest mathk Posted April 23, 2012 Report Share Posted April 23, 2012 I am trying to load a simple test.bit bitstream file with the papilio-prog but I got an error. [tt] $ papilio-prog -f test.bit Could not access USB device 0403:6010.[/tt] It is a papilio-prog compile from github. I did have a quick look at the source code and add more debug information and here is the actual output: [tt]ftdi_usb_open_desc: unable to claim usb device. Make sure the default FTDI driver is not in use.[/tt] It seems to me that I am missing some driver. Thanks for the help Link to comment Share on other sites More sharing options...
