+__TOC__
+=Overview=
+This page presents a guide about how to recover your board when it is not booting.
+In order to recover your board, some components are required to be built in specific folders.
+Required components:
+# U-Boot
+# Flash Image
+# USB Loader
+Define a building directory:
+<syntaxhighlight lang=bash>
+RECOVERY_DIR=~/Nitrogen8M-recovery
+mkdir $RECOVERY_DIR
+</syntaxhighlight>
+=Dependencies=
+Install required dependencies for Nitrogen8M recovery:
+<syntaxhighlight lang=bash>
+sudo apt-get install crossbuild-essential-arm64 libusb-1.0-0-dev pkg-config
+<syntaxhighlight>
+=U-Boot=
+Clone Boundary Devices repository using your desired U-Boot version.
+<syntaxhighlight lang=bash>
+BRANCH=boundary-v2018.07
+cd $RECOVERY_DIR
+git clone https://github.com/boundarydevices/u-boot-imx6 -b $BRANCH
+</syntaxhighlight>
+Define toolchain for building the source code.
+<syntaxhighlight lang=bash>
+export ARCH=arm64
+export CROSS_COMPILE=aarch64-linux-gnu-
+</syntaxhighlight>
+Build kernel and device tree.
+<syntaxhighlight lang=bash>
+DEFCONFIG=nitrogen8m_defconfig
+cd $RECOVERY_DIR/u-boot-imx6
+make $DEFCONFIG
+make -j4
+</syntaxhighlight>
+=Building Image=
+In order to generate the final flash file, '''imx-mkimage''' tool is required.
+Download imx-mkimage tool as follows.
+<syntaxhighlight lang=bash>
+cd $RECOVERY_DIR
+git clone https://github.com/boundarydevices/imx-mkimage.git
+</syntaxhighlight>
+Define required variables.
+<syntaxhighlight lang=bash>
+UBOOT_PATH=$RECOVERY_DIR/u-boot-imx6
+</syntaxhighlight>
+Create the flash image.
+<syntaxhighlight lang=bash>
+cd imx-mkimage
+./make_boundary.sh
+</syntaxhighlight>
+At this point, a '''flash.bin''' file should be created under '''$RECOVERY_DIR/imx-mkimage/iMX8M'''.
+=USB loader=
+Before flashing the board, build the flashing tool '''imx_usb''' as follows.
+<syntaxhighlight lang=bash>
+cd $RECOVERY_DIR
+git clone git://github.com/boundarydevices/imx_usb_loader
+cd imx_usb_loader
+make
+</syntaxhighlight>
+=Flashing Board=
+Finally, under RECOVERY_DIR you must have 3 directories:
+# imx-mkimage: Image to flash.
+# imx_usb_loader: Flashing tool.
+# u-boot-imx6: U-Boot used by image to flash.
+Set your board to '''Serial Download''' mode, set the boot switch position as follows.
 [[File:Nitrogen8m_recovery_sw.png|400px|center|Boot switch on Nitrogen8M]]
+Now, connect the board to a host machine using the OTG port.
+Check with '''lsusb''' if your board is detected.
+Output example:
+<syntaxhighlight lang=bash>
+user@laptop:~$ lsusb | grep NXP
+Bus 001 Device 047: ID 1fc9:012b NXP Semiconductors
+</syntaxhighlight>
+Before flashing, check '''mx8mq_usb_work.conf''' in RECOVERY_DIR/imx_usb_loader which contains the required files.
+As example, the Nitrogen8M with 2 GB RAM requires the file '''bl31_2g.bin''' in '''mx8mq_usb_work.conf'''.
+In order to flash the board, run the following command:
+<syntaxhighlight lang=bash>
+sudo ./imx_usb
+</syntaxhighlight>
+Output example:
+<syntaxhighlight lang=bash>
+config file <.//imx_usb.conf>
