BSH SMM S2 (SystemMaster S2) 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 5.18
- mainline U-Boot 2022-07-rc2
- default packages from buildroot
Patches applied to the Linux kernel and U-Boot have been submitted but
not merged yet.
Michael Trimarchi has been added as co-maintainer.

+Subject: [PATCH] dmaengine: mxs: fix driver registering
+
+Driver registration fails on SOC imx8mn as its supplier, the clock
+control module, is not ready. Since platform_driver_probe(), as
+reported by its description, is incompatible with deferred probing,
+we have to use platform_driver_register().
+

+Subject: [PATCH 02/10] mtd: nand: mxs_nand_spl: Fix bad block skipping
+
+The specific implementation was having bug. Those bugs are since
+the beginning of the implementation. Some manufactures can already
+experience this bug in their SPL code. This bug can be more visible on
+architecture that has complicated boot process like imx8mn. Older
+version of uboot can be affected if the bad block
+appear in correspoding of the beginning of u-boot image. In order to
+adjust the function we scan from the first erase block.
+
+The problematic part of old code was in this part:
+
+while (is_badblock(mtd, offs, 1)) {
+ page = page + nand_page_per_block;
+ /* Check i we've reached the end of flash. */
+ if (page >= mtd->size >> chip->page_shift) {
+ free(page_buf);
+ return -ENOMEM;
+ }
+}
+
+Even we fix it adding increment of the offset of one erase block size
+, we don't fix the problem, because the first erase block where the
+image start is not checked. The code was tested on an imx8mn where
+the boot rom api was not able to skip it. This code is used by other
+architecures like imx6 and imx8mm

+
+The badblock should be skipped properly in reading and writing.
+Fix the logic. The bcb struct is written, skipping the bad block,
+so we need to read using the same logic. This was tested create
+bad block in the area and then flash it and read it back.

+If the fitImage has some bad block in fit image area, the

+After implementing it in mxs now is possible to call the function

+i.MX8MN BSH SMM S2
+==================
+
+This tutorial describes how to use the predefined Buildroot
+configuration for the i.MX8MN BSH SMM S2 PRO board.
+
+Building
+--------
+
+Configure buildroot:
+
+ $ make imx8mn_bsh_smm_s2_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
+ ├── ddr3*
+ ├── flash.bin
+ ├── freescale/imx8mn-bsh-smm-s2.dtb
+ ├── Image
+ ├── nand-full.lst
+ ├── rootfs.ext2
+ ├── rootfs.ext4 -> rootfs.ext2
+ ├── rootfs.tar
+ ├── rootfs.ubifs
+ ├── u-boot.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
+--------
+
+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:
+
+ $ nand erase.chip
+ $ reset
+
+Flash the built images directly to board’s memory. On your computer,
+run:
+
+ $ board/bsh/imx8mn-bsh-smm-s2/flash.sh output/
+
+It will flash the bootloader, the Device Tree Blob, the kernel image
+and the UBI root file system.
