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
|
