[Buildroot] [PATCH v3 1/5] package/freescale-imx: add option for i.MX 8M Plus

[Stephane Viau]

The i.MX 8M Plus focuses on machine learning and vision and industrial
automation. It also provides advanced multimedia, including a VPU and
the GPU GC7000UL (3D) + GC520L (2D).

[Buildroot] [PATCH v3 5/5] configs/freescale_imx8mpevk: new defconfig

[Stephane Viau]

This patch adds support for the NXP i.MX 8M Plus EVK board [1].

The final boot image is created from uboot and firmware binaries in post
image script board/freescale/common/imx/imx8-bootloader-prepare.sh.

This first support is based on NXP's 5.4.70_2.3.0 BSP.

+*********************
+NXP i.MX8MP EVK board
+*********************
+
+This file documents the Buildroot support for the i.MX 8M Plus EVK board.
+
+Build
+=====
+
+First, configure Buildroot for the i.MX 8M Plus EVK board:
+
+  make freescale_imx8mpevk_defconfig
+
+Build all components:
+
+  make
+
+You will find in output/images/ the following files:
+  - bl31.bin
+  - boot.vfat
+  - ddr_fw.bin
+  - Image
+  - imx8-boot-sd.bin
+  - imx8mp-evk.dtb
+  - lpddr4_pmu_train_fw.bin
+  - rootfs.ext2
+  - rootfs.ext4
+  - rootfs.tar
+  - sdcard.img
+  - u-boot.bin
+  - u-boot.itb
+  - u-boot-nodtb.bin
+  - u-boot-spl.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.MX 8M Plus EVK board
+===============================
+
+To boot your newly created system (refer to the i.MX 8M Plus EVK Documentation
+[1] for guidance):
+- insert the SD card in the SD slot of the board;
+- Configure the switches as follows (X = "don't care"):
+SW4:	0011 SW4[1-4]
+- 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!
