Overview
The U-Boot boot-loader is used for low-level initialization and operating system loading.
Building U-BOOT for iMX8M-NANO-CM
This U-BOOT is based on https://source.codeaurora.org/external/imx/uboot-imx.git, branch imx_v2020.04_5.4.24_2.1.0
Setup the cross compiler and CPU architecture
$ export ARCH=arm64 $ export CROSS_COMPILE=/opt/cross/aarch64-ronetix-linux-11.1/bin/aarch64-ronetix-linux-gnu-
Cross compiler can be downloaded from here: http://download.ronetix.at/toolchains/crosstool-ng
Clone the latest revision of the repo
$ git clone https://github.com/ronetix/u-boot.git u-boot-ronetix --depth=1 -b imx_v2020.04_5.4.24_2.1.0_rnx $ cd u-boot-ronetix
Configure
$ make imx8mn_cm_defconfig
Download and build i.MX8M firmware
$ source tools/imx8m_build_firmware.sh imx8mn
Build
$ make flash.bin
Build Results
File Name | Description |
---|---|

u-boot-dtb.imx | U-BOOT image with DTB |
flash.bin | U-BOOT image with DTB and firmware |
Flashing U-BOOT image to a SD card
Replace sdX with the right device name.
$ sudo dd if=flash.bin of=/dev/sdX bs=1k seek=32 conv=fsync
