Manual setup
U-Boot
This board or SoC are not yet supported in mainline U-Boot as of v2017.09.
To get to a U-Boot prompt, you may need to enter s500 on the serial console. You can disable this in include/configs/s500.h.
git clone https://github.com/sparkysbc/sparky_sdk.git cd sparky_sdk/u-boot make actduino_s500_v12_defconfig make u-boot-dtb.img (cd ../owl/scripts; ./padbootloader ../../u-boot/u-boot-dtb.img ) cd ../..
You may want to tweak board/actions/owl/owl_boot_fdt.c to not add console=ttyS3 and Android cruft to $bootargs.
