Freescale i.MX8MN EVK board
***************************
This file documents the Buildroot support for the i.MX8M Nano EVK board.
Build
=====
First, configure Buildroot for the i.MX8MN EVK board:
make freescale_imx8mnevk_defconfig
Build all components:
make
You will find in output/images/ the following files:
- bl31.bin
- boot.vfat
- ddr4_201810_fw.bin
- ddr_fw.bin
- fsl-imx8mn-ddr4-evk.dtb
- Image
- imx8-boot-sd.bin
- rootfs.ext2
- rootfs.ext4
- rootfs.tar
- sdcard.img
- u-boot.bin
- u-boot.imx
- u-boot.itb
- u-boot-nodtb.bin
- u-boot-spl.bin
- u-boot-spl-ddr.bin
Create a bootable SD card
=========================
To determine the device associated to the SD 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 SD card. Launch the following
command as root:
dd if=output/images/sdcard.img of=/dev/<your-sd-device>
*** 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_imx8.
Boot the i.MX8MN EVK board
==========================
To boot your newly created system (refer to the i.MX8MNano EVK Quick Start Guide
[1] for guidance):
- insert the SD card in the SD slot of the board;
- Configure the switches as follows (X = "don't care"):
SW1101: 1100XXXXXX [D1-D10]
SW1102: XXXXXXXXXX [D1-D10]
- put a micro USB cable into the Debug USB Port and connect using a terminal
emulator at 115200 bps, 8n1;
- power on the board.
Enjoy!
