Hi Gunnar, I tried booting the RPI2 image from https://raspi.debian.net/daily/raspi_2.img.xz Boot fails. It never leaves the colorful screen on HDMI. Rebuilding the image myself worked. But even then, the serial console does not work (only HDMI worked). The image uses console=ttyS1 in cmdline.txt, while the serial port is named ttyAMA0 on this board. Lucas
