Changes v4 -> v5:
- don't creates boot.img partition, uses directly barebox-socfpga-de10_nano-xload.img instead (Thomas)
Changes v3 -> v4:
- fix genimage.cfg indent (Thomas)
- drop rootfs size from genimage.cfg, use BR2_TARGET_ROOTFS_EXT2_SIZE instead (Thomas)
- s/BR2_KERNEL_HEADERS_5_11/BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_5_11/g (Thomas)
Changes v2 -> v3:
- use barebox default version: v2021.07.0 is now released with DE10 Nano support
Changes v1 -> v2:
- add defconfig and board path in DEVELOPERS

+Terasic DE10 Nano Development Board
+
+Intro
+=====
+
+More information about this board can be found here:
+https://rocketboards.org/foswiki/Documentation/DE10NanoDevelopmentBoard
+
+Build
+=====
+
+First, load socrates config for buildroot
+
+ make terasic_de10nano_cyclone5_defconfig
+
+Build everything
+
+ make
+
+Following files will be generated in output/images
+

+
+Creating bootable SD card
+=========================
+
+Simply invoke
+
+dd if=output/images/sdcard.img of=/dev/sdX
+
+Where X is your SD card device (not partition)
