Waveshare delivered a binary kernel (so much about GPL) for their 7" HDMI C until they changed something in the device firmware and upgraded for a newer panel about 2-3 years ago. This is the 10.1" HMDI B and it is a very early version I have, which however should use a firmware similar to the newer 7" HDMI C. I will retest with a stock Raspbian image to be sure I wasn't accidently using a Waveshare image back then. As far as I can see the Linux drivers just quirk the device to the egalaxy driver, so they do know the Waveshare by ID. I couldn't spot a difference between Linux and what is included in the webcamd source. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
