NetBSD runs on the Terasic DE0 Nano-SoC board, based on the Altera/Intel Cyclone V. The evbearmv7hf-el version of NetBSD should be used.

Hardware supported

Currently, ethernet, USB, micro-SD slot, and UART are supported. FPGA, GPIO's, SPI, ADC, accelerometer, and so on are not yet supported.

Image build and installation

Basically, you need to dd u-boot from sysutils/u-boot-de0-nanosoc into a new partition of type 162 (0xA2) in armv7.img, and that's it.

Here are the precise instructions under NetBSD.

$ gunzip -c armv7.img.gz > armv7-for-nanosoc.img
$ fdisk -f -u -2 -s 162/2048/2048 armv7-for-nanosoc.img
$ dd if=/usr/pkg/share/u-boot/de0-nanosoc/u-boot-with-spl.sfp of=armv7-for-nanosoc.img seek=2048 conv=notrunc
# dd if=armv7-for-nanosoc.img of=/dev/rXXN bs=1m conv=sync
