+*****************
+Warp i.MX7S board
+*****************
+
+This file documents the Buildroot support for the Warp i.MX7S board.
+
+Build
+=====
+
+First, configure Buildroot for the Warp i.MX7S board:
+
+  make warp7_defconfig
+
+Build all components:
+
+  make
+
+You will find in output/images/ the following files:
+  - imx7s-warp.dtb
+  - rootfs.ext4
+  - rootfs.tar
+  - sdcard.img
+  - u-boot.imx
+  - zImage
+
+Flash the eMMC image
+====================
+
+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 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 into the eMMC. Launch the following
+command:
+
+sudo dd if=output/images/sdcard.img of=/dev/<your-emmc-device>
+
+*** WARNING! This will destroy all the eMMC content. Use it with care! ***
+
+For details about the medium image layout, see the definition in
+board/warp7/genimage.cfg.
+
+How to recover from a bad eMMC image
+====================================
+
+In case a bad U-Boot has been flashed to the eMMC and the board no
+longer boots, it is possible to recover using the imx_usb_loader utility.
+
+Put the warp7 board in USB download mode by removing the CPU board
+from the base board then putting switch 2 in the upper position.
+
+Connect a USB to serial adapter between the host PC and warp7 serial
+USB port, and also a USB cable between the OTG warp7 port and the host
+PC.
+
+Copy u-boot.imx to the imx_usb_loader folder.
+
+Load u-boot.imx via USB:
+
+$ sudo ./imx_usb u-boot.imx
+
+Then U-Boot should start and its messages will appear in the console program.
+
+Open a terminal program such as minicom.
+
+Use the default environment variables:
+
+=> env default -f -a
+=> saveenv
+=> ums 0 mmc 0
+
+sudo dd if=output/images/sdcard.img of=/dev/<your-emmc-device>
+
+Put warp7 back in eMMC boot mode by placing switch 2 in the lower position
+and reboot the board.
+
+Boot the Warp i.MX7S 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!
