********************* * 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 https://docs.creatordev.io/ci40/guides/openwrt-platform/#overview
