======================
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.
