Dear all, I try to print debug information from the boot process. Therefore, I connected a serial-to-usb connector with 3 1-pin cables to the white CON2 connector on tiny4412. However, using PuTTy I dont receive anything while booting the stock linux version. Here is a picture of my setup: http://fs2.directupload.net/images/150423/9zwagv24.jpg What am I doing wrong? I know that the converter works as I used it to print information via UART for other hardware.
