i.MX8MN BSH SMM S2 PRO
======================

How to build it
---------------

Configure buildroot:

$ make imx8mn_bsh_smm_s2_pro_defconfig

Change settings to fit your needs (optional):

$ make menuconfig

Compile everything and build the rootfs image:

$ make


Result of the build
-------------------

After building, the output/images directory contains:

output/images/
├── bl31.bin
├── Image
├── flash.bin
├── ddr3*
├── rootfs.ext2
├── rootfs.ext4 -> rootfs.ext2
├── rootfs.tar
├── sdcard.img
├── u-boot.bin
├── u-boot-nodtb.bin
└── u-boot-spl.bin


Preparing the board
-------------------

Plug the USB type A to micro B cable into the USB Debug
Connector (DBG UART). Use serial port settings 115200 8N1
to access the debug console.

Plug another USB type A to micro B cable into the USB-OTG
Connector (USB1). This connection is used to flash the board
firmware using the Freescale/NXP UUU tool.

Connect the power supply/adaptor to the DC Power Jack (labelled
+5V).


Flashing the emmc card image
----------------------------

Power up the board by switching on the Power ON Switch, which is
placed right next to the DC Jack.

Enter the following U-Boot commands on the debug serial console:

$ fastboot usb 0

Flash the images on eMMC. On your computer, run:

$ board/bsh/imx8mn-bsh-smm-s2-pro/flash.sh output/


Booting the board
-----------------

By default the bootloader will search for the first valid image,
starting with the internal eMMC.
