*********************
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
