| i.MX8MN BSH SMM S2 PRO |
| ====================== |
| |
| How to build it |
| --------------- |
| |

| |
| $ make imx8mn_bsh_smm_s2_pro_defconfig |
| |

| |
| 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. |
