This file documents the Buildroot support for the Technexion i.MX6UL Pico board.
|
|
Build
|
=====
|
|
First, configure Buildroot for the i.MX6UL Pico board:
|
|
make imx6ulpico_defconfig
|
|
Build all components:
|
|
make
|
|
You will find in output/images/ the following files:
|
- imx6ul-pico-hobbit.dtb
|
- rootfs.ext4
|
- rootfs.tar
|
- sdcard.img
|
- u-boot.imx
|
- zImage
|
|
Create a bootable SD card
|
=========================
|
|
In the U-Boot prompt lauch:
|
|
=> ums 0 mmc 0
|
|
This will mount the eMMC content in the host PC as a mass storage device.
|
|
To determine the device associated to the eMMC 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 the eMMC 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.
|
|
Boot the i.MX6UL Pico board
|
=========================
|
|
To boot your newly created system:
|
- put a micro USB cable into the Debug USB Port and connect using a terminal
|
emulator at 115200 bps, 8n1;
|
- power on the board.
|
|
Using Wifi
|
==========
|
|
# modprobe brcmfmac
|
# iwconfig wlan0 essid ACCESSPOINTNAME
|
# wpa_passphrase ACCESSPOINTNAME > /etc/wpa.conf
|
(enter the wifi password and press enter)
|
# wpa_supplicant -Dwext -iwlan0 -c /etc/wpa.conf &
|
# udhcpc -i wlan0
|
# ping buildroot.org
|
