The Meerkat96 board, based on the NXP i.MX7D SoC, is a member of 96Boards community and complies with all Consumer Edition board specifications. https://www.novtech.com/products/meerkat96.html https://www.96boards.org/product/imx7-96/ The initial supported/tested devices include: - Debug serial - SD - USB Host (with Ethernet) With these support, it's good enough for loading Linux Kernel from SD or Ethernet over USB.
