The HDMI2USB device has two different firmware, one for the FPGA and one for the Cypress FPGA chip.
- The *.hex file is for the Cypress USB chip.
- The *.bit file is for the Xilinx FPGA chip.
Prebuilt Firmware can be found in the HDMI2USB-firmware-prebuilt repository.
Current firmware is found in the base directory in two versions;
- Stable version - use this in production
- hdmi2usb-stable.bit
- hdmi2usb-stable.hex
- Testing version - use this to get the latest and greatest features
- hdmi2usb-testing.bit
- hdmi2usb-testing.hex
Older versions of the firmware can be found in the Archive directory.
The drivers directory contains the driver code to use the device. This is only required under Windows but can be helpful under Linux.
FIXME: Explain the inf file.
The Linux driver can autoload the HDMI2USB firmware onto a Digilent Atlys Board, allowing you to just plug in the device and have it work.
If you have a Digilent Atlys Board (and are not using the Linux drivers which auto-load the firmware or on Windows), you should follow the instructions at Digilent Atlys Board: Loading Firmware to load the firmware.
