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.
