| 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/usr/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/usr/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 |
| |
