NUC980 ARM9 board design with 2 layer PCB. SW Rootfs built from BuildrootAs this SoC has only 64MB DDR memory, 128MB SPI-Nand flash, rootfs must be in minimal, buildroot is a suitable for such case. The images are quite small: HWThe design is in 2 parts, one is the core board, which export the NUC980 Pins using DIP. Part 2 is the base board, which export some interfaces and storage for production purpose.
