i.MX6ULZ BSH SMM M2
==================
This tutorial describes how to use the predefined Buildroot
configuration for the i.MX6ULZ BSH SMM M2 board.
Building
--------
Configure buildroot:
$ make imx6ulz_bsh_smm_m2_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/
├── imx6ulz-bsh-smm-m2.dtb
├── zImage
├── nand-full.lst
├── rootfs.ubifs
└── u-boot-with-spl.imx
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/imx6ulz-bsh-smm-m2/flash.sh output/
It will flash the bootloader, the Device Tree Blob, the kernel image
and the UBI root file system.
