Step-by-step instructions

• Download Yocto image for UDOO NEO - 20151109191206

• Unzip the *.rootfs.sdcard.gz file $ gunzip core-image-full-cmdline-udooneo-20151109191206.rootfs.sdcard.gz

• Write the *.rootfs.sdcard file (i.e. on Windows, use Win32DiskImager) onto a blank Micro SD

• Insert the Micro SD

• Watch U-Boot and Linux console messages on the debug serial

• When getting the udooneo login prompt, login as root
