Vector22 Posted April 5, 2019 Report Share Posted April 5, 2019 As my first project using the Papilio Pro and LogicStart MegaWing, I made LEDs turn on from the switches. When I use the Papilio Loader 2.8 to write to FPGA, it executes fine and I am able to turn on the LEDs. When I try to write to SPI Flash, however, it times out and displays the following error message: readusb: Timeout readusb terminate called after throwing an instance of 'io_exception' What am I doing wrong?
