The 4 pin is the UART connection. With the power button towards you and the DVI connection away from you the connections are as follows: GND, TX, RX, VCC (from left to right). kernelLinux Kernel 6.6.2 MVEBU package and Debian armhf rootfs https://forum.doozan.com/read.php?2,32146 mkfs.ext3 -L rootfs /dev/sda1 mount /dev/sda1 /mnt/sda1/ cd /mnt/sda1/ tar xvf /nuc/armada/Debian-6.6.2-mvebu-tld-1-rootfs-bodhi.tar.bz2 3.
