- Freescale i.MX8MM EVK board
- ***************************
- This file documents the Buildroot support for the Freescale i.MX8MM
- EVK board.
- Build
- =====
- First, configure Buildroot for the i.MX8MM EVK board:
- make freescale_imx8mmevk_defconfig
- Build all components:
- make
- You will find in output/images/ the following files:
- - bl31.bin
- - boot.vfat
- - fsl-imx8mm-evk.dtb
- - Image
- - imx8-boot-sd.bin
- - lpddr4_pmu_train_fw.bin
- - rootfs.ext2
- - rootfs.ext4
- - rootfs.tar
- - sdcard.img
- - u-boot.bin
- - u-boot.imx
- - u-boot-nodtb.bin
- - u-boot-spl-ddr.bin
- Create a bootable SD card
- =========================
- To determine the device associated to the SD card have a look in the
- /proc/partitions file:
- cat /proc/partitions
- Buildroot prepares a bootable "sdcard.img" image in the output/images/
- directory, ready to be dumped on a SD card. Launch the following
- command as root:
- dd if=output/images/sdcard.img of=/dev/<your-sd-device>
- *** WARNING! This will destroy all the card content. Use with care! ***
- For details about the medium image layout, see the definition in
- board/freescale/common/imx/genimage.cfg.template_imx8.
- Boot the i.MX8MM EVK board
- ==========================
- To boot your newly created system (refer to the i.MX8MMini EVK Quick Start Guide
- [1] for guidance):
- - insert the SD card in the SD slot of the board;
- - Configure the switches as follows:
- SW1101: 0110110010 [D1-D10]
- SW1102: 0001101000 [D1-D10]
- - put a micro USB cable into the Debug USB Port and connect using a terminal
- emulator at 115200 bps, 8n1;
- - power on the board.
- Enjoy!
