I am connecting the usb to udoo but my computer says "the found device is unknown device". I followed putty tutorial from the net. I successfully installed the cp210x driver for my 64 bit windows pc. Putty works also well but not connecting to the com port. I tried lots of comX to connect(115200 baud). http://www.udoo.org/tutorial/connecting-via-serial-cable/ I think my cp2104 chip burned because of 5V+ or shortcut in the usb cable. I want to change it with new one but i would like to ask you what should i do. I bought LVDS 7'' panel but i can't connect to the uart and cant set the lvds setup string for Android. When I am using ubuntu, there is an udoo tool for lvds setup, It works well for ubuntu and not requires putty - lvds setup string. Is there any way to connect boot and set options without usb(cn6 for udoo Quad)? My requirements needs Android with Touchscreen. If it is possible to set the boot options(For Android LVDS) from ubuntu when OS opened, i will be happy to learn how can i do it. Thanks.
