Created page with "{{#vardefine:HARDWARE_NAME|i.MX7-CM}} {{#vardefine:UBOOT_TAG|v2019.10}} {{#vardefine:DEFCONFIG_NAME|imx7_cm_defconfig}}  [[File:iMX7-CM top.png|thumb]..."

New page

= Overview =
The U-Boot boot-loader is used for low-level initialization and operating system loading.

= Building U-BOOT for {{#var:HARDWARE_NAME}} =
This U-BOOT is based on https://github.com/u-boot/u-boot.git, tag {{#var:UBOOT_TAG}}
==== Setup the cross compiler and CPU architecture ====
$ export ARCH=arm
$ export CROSS_COMPILE=/opt/cross/arm-ronetix-eabi-8.3.0/bin/arm-ronetix-eabi-

==== Clone the latest revision of the repo ====
$ git clone https://github.com/ronetix/u-boot.git u-boot-ronetix --depth=1
$ cd u-boot-ronetix

==== Configure and build ====
$ make {{#var:DEFCONFIG_NAME}}
$ make

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

The U-BOOT image should be at address 0x400 on the SD card.
