Technexion i.MX6UL Pico board
*****************************
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/technexion/imx6ulpico/genimage.cfg.
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
Enjoy!
