| 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. |
