+* MIPS Creator CI40 *
+*********************
+
+This document details how to build and run a Buildroot system on the
+MIPS Creator CI40 platform. For more details about the CI40, see
+https://creatordev.io/ci40-iot-hub.html.
+
+How to build
+------------
+
+$ make ci40_defconfig
+$ make
+
+Prepare USB/MMC for boot
+------------------------
+
+On successful build, "sdcard.img" file will be created in 'output/images'
+folder.
+
+Use following command to write image to bootable device
+
+$ sudo dd if=./output/images/sdcard.img of=/dev/<your-microsd-or-usb-device>
+
+Booting from USB/MMC
+--------------------
+
+The boot loader is already present in NOR flash. To boot your newly generated
+Linux and root filesystem, you need to interrupt U-Boot autoboot. Current
+U-Boot is configured with 2 seconds of boot-delay, after expiry of this
+boot-delay timeout U-Boot starts booting the default image. To interrupt
+autoboot, press any key before the boot-delay time expires, U-Boot will
+stop the autoboot process and give a U-Boot prompt. You can now boot to
+your preferred boot method as describe below:
+
+From USB
+ pistachio # run usbboot
+
+From SD-Card
+ pistachio # run mmcboot
+
+Persistent boot command
+-----------------------
+
+To boot automatically to your preferred boot method, use following command to
+make it persistent, for example to automatically boot to usb:
+
+ pistachio # setenv bootcmd run usbboot
+ pistachio # saveenv
+
+Flash new bootloader
+--------------------
+
+The bootloader image will be available in the 'output/images' folder. To flash
+the new bootloader, copy it to the device and use the following command on the
+device:
+
+# flashcp -v u-boot-pistachio_marduk-<version>.img /dev/mtd0
+
+Online docs
+-----------
+
+Mostly for OpenWRT but it is applicable to Buildroot
