From: Michael Trimarchi <michael@amarulasolutions.com>

BSH SMM S2 PRO (SystemMaster S2 Pro) Board is an add-on board which
provide input and output interfaces to a dedicated carrier board. It is
designed mainly to provide graphical/video and connectivity interfaces
to the appliance.

Board support package includes the following components:
- mainline Linux kernel 5.19.7
- mainline U-Boot 2022-07
- Default packages from buildroot

https://www.apertis.org/reference_hardware/imx8mn_bsh_smm_s2pro_setup/

Add Ariel D'Alessandro and Dario Binacchi as co-maintainer, we work
together on platform mainline

Build and tested using:
docker pull registry.gitlab.com/buildroot.org/buildroot/base:20220105.2314

The board boots from eMMC. The board/bsh/imx8mn-bsh-smm-s2-pro/flash.sh

Ah ok. I'm not familiar with the uuu tool. Nevertheless, the offset in
the genimage config looks wrong to me. If you want to install the
created image without the uuu tool it will probably not work, because
the imx8mn processor expects the bootloader (flash.bin) image at
offset 32k.

+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.
