*************************** Freescale i.MX6UL EVK board *************************** This file documents the Buildroot support for the Freescale i.MX6UL EVK board. Please read the i.MX6UL Evaluation Kit Quick Start Guide [1] for an introduction to the board. Build ===== First, configure Buildroot for your i.MX6UL EVK board: In order to to do so there are two supported options: make freescale_imx6ulevk_defconfig if you plan to use NXP provided U-Boot and kernel. or make imx6ulevk_defconfig if you plan to use mainline U-Boot and mainline kernel. Build all components: make You will find in ./output/images/ the following files: - imx6ul-14x14-evk.dtb - rootfs.ext4 - rootfs.tar - sdcard.img - u-boot.imx - zImage Create a bootable microSD card ============================== To determine the device associated to the microSD card have a look in the /proc/partitions file: cat /proc/partitions Buildroot prepares a bootable "sdcard.img" image in the output/images/ directory, ready to be dumped on a microSD card. Launch the following command as root: dd if=./output/images/sdcard.img of=/dev/ *** WARNING! This will destroy all the card content. Use with care! *** For details about the medium image layout, see the definition in board/freescale/common/imx/genimage.cfg.template. Boot the i.MX6UL EVK board ========================= To boot your newly created system (refer to the i.MX6UL EVK Quick Start Guide [1] for guidance): - insert the microSD card in the microSD slot of the board; - verify that your i.MX6UL EVK board jumpers and switches are set as mentioned in the i.MX6UL EVK Quick Start Guide [1]; - put a micro USB cable into the Debug USB Port and connect using a terminal emulator at 115200 bps, 8n1; - power on the board.
