The TS-7680 features are 10/100 Ethernet ports, +Wi-Fi, microSD card, eMMC, NOR Flash, USB host port, CAN ports, +relays and ADC/DAC. More details on the board here: +https://wiki.embeddedarm.com/wiki/TS-7680 + +The TS-7680 uses a 3.14.28 Linux kernel provided by +Technologic Systems. + +To build the default configuration you only have to run: + + $ make ts7680_defconfig + $ make + +The output looks like: +output/images +├── imx28-ts7680.dtb +├── rootfs.ext2 +├── rootfs.ext4 -> rootfs.ext2 +├── rootfs.tar +├── sdcard.img +└── uImage + +The provided genimage configuration generates an image file containing +two partitions.
