[Buildroot] [PATCH 1/1] New board - EVB SoCrates based on Altera Cyclone 5
Michał Łyszczek
michal.lyszczek at gmail.com
Tue Aug 1 20:10:13 UTC 2017
From: Michał Łyszczek <michal.lyszczek at bofc.pl>
Configuration contains:
- binary uboot SPL
- building uboot from altera's github
- booting from SD card
- working ethernet, serial, spi, i2c, fpga_manager, gpio
- minimal rootfs with busybox (~3.5Mb)
- ready to flash SD card image
Signed-off-by: Michał Łyszczek <michal.lyszczek at bofc.pl>
---
Changes v1 -> v2:
- removed binary SPL (all compiled from source now)

+EBV SoCrates Evaluation Board
+
+Intro
+=====
+
+More information about board can be found here:
+https://rocketboards.org/foswiki/Documentation/EBVSoCratesEvaluationBoard
+
+Build
+=====
+
+First, load socrates config for buildroot
+
+ make socrates_cyclone5_defconfig
+
+Build everything
+
+ make
+
+Following files will be generated in output/images
+
+.
+├── boot.scr
+├── boot.vfat
+├── boot_partition.img
+├── linux.dtb
+├── preloader.bin
+├── rootfs.ext2
+├── rootfs.ext4 -> rootfs.ext2
+├── rootfs.tar
+├── sdcard.img
+├── u-boot.bin
+├── u-boot.img
+├── uboot-env.bin
+└── zImage
+
+
+Creating bootable SD card
+=========================
+
+Simply invoke
+
+dd if=output/images/sdcard.img of=/dev/sdX
+
+Where X is your SD card device (not partition)
+
+Booting
+=======
+
+Pins 6:8 on P18 selector is used to determine boot device. To boot socrates from
+sdcard set these pins to value 0x5 (101b). Rest pins are used to determine how
+to configure FPGA and are not associate with booting into Linux kernel.
