RIPE Atlas Probe v5 is a network measurement device based on Turris MOX. u-boot bootscript supports booting both from the original Turris BTRFS layout and default OpenWrt ext4 boot + root partition layout. Specifications: * SoC: Marvell ARMADA 3720 * RAM: 512 MiB, DDR3 * eMMC: 4G * Ethernet: 1x 1GbE MAC: LAN MAC: label on board Flash instructions: * For using the default ext4 layout, boot into a live system using tftpboot in u-boot and flash an OpenWrt SD image onto /dev/mmcblk0. * For the Turris layout, put the new rootfs into subvolume '@', not forgetting to add Image, device tree, and boot.scr to /boot. Misc: * USB connection is only for power. For UART access use the pin header: 1: GND 2: +1.8V 5: TX 6: RX * Flashing the image onto Turris Shield won't work. Use Turris MOX image instead.
