Build
=====
First, configure Buildroot for your WarpBoard.
make warpboard_defconfig
Build all components:
make
You will find in ./output/images/ the following files:
- imx6sl-warp.dtb
- rootfs.ext4
- rootfs.tar
- sdcard.img
- u-boot.imx
- zImage
Update uboot
============
- Put warpboard in USB download mode by closing the j2 jumper on the
daugther board
- Load u-boot.imx in the WarpBoard by using the imx-usb-loader host utility:
$ ./output/host/bin/imx_usb -c output/host/etc/imx-loader.d/ output/images/u-boot.imx
- U-Boot will appear in minicom
- Reset the U-Boot environment to its default:
=> env default -f -a
=> saveenv
- Run the DFU command in U-Boot:
=> dfu 0 mmc 0
- Transfer U-Boot into flash by running this command in host side:
$ sudo ./output/host/bin/dfu-util -D output/images/u-boot.imx -a boot
- remove power and put the WarpBoard back into normal boot mode by
opening the j2 jumper.
Update linux & rootfs
=====================
Run the 'ums' command from the U-Boot prompt to mount the eMMC as USB mass
storage:
=> ums 0 mmc 0
And then flash the sdcard.img into the eMMC:
dd if=output/images/sdcard.img of=/dev/<your-sd-device>
*** WARNING! This will destroy all the eMMC content. Use it with care! ***
Using bluetooth
================
Enable the bluez_utils or bluez5_utils package, and then run:
$ hciattach /dev/ttymxc4 any
$ hciconfig hci0 up
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
