| Buildroot for Engicam i.CoreM6 SOM platforms: |
| ********************************************* |
| |
| This file documents the Buildroot support for Engicam i.CoreM6 |
| platform boards. |
| |
| i.CoreM6 Quad/Dual/DualLite/Solo SOM Starter kits: |
| https://www.engicam.com/vis-prod/101120 |
| i.CoreM6 Quad/Dual/DualLite/Solo Open Frame 10.1 C.TOUCH kits: |
| https://www.engicam.com/vis-prod/101133 |
| |
| This configuration uses U-Boot mainline and kernel mainline. |
| |
| Build |
| ===== |
| |
| First, configure Buildroot for the Engicam i.CoreM6: |
| |
| make engicam_imx6qdl_icore_defconfig |
| |
| Build all components: |
| |
| make |
| |
| You will find the following files in output/images/: |
| - imx6q-icore.dtb (for i.CoreM6 Quad/Dual) |
| - imx6dl-icore.dtb (for i.CoreM6 DualLite/Solo) |
| - imx6q-icore-ofcap10.dtb (for i.CoreM6 Quad/Dual ofcap 10) |
| - imx6q-icore-ofcap12.dtb (for i.CoreM6 Quad/Dual ofcap 12) |
| - rootfs.ext4 |
| - rootfs.tar |
| - sdcard.img |
| - SPL |
| - u-boot-dtb.img |
| - uImage |
| |
| 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> |
| sync |
| |
| *** WARNING! This will destroy all the card content. Use with care! *** |
| |
| For details about the medium image layout, see the definition in |
| board/engicam/icorem6/genimage.cfg |
| |
| Boot the i.CoreM6 boards with SD boot: |
| ===================================== |
| |
| To boot your newly created system: |
| - insert the SD card in the SD slot of the board; |
| - connect 3-wire RS232 serial port J28 on board, and connect with other |
| serial end or USB cable(if serial-to-usb converter used) using |
| a terminal emulator at 115200 bps, 8n1; |
| - close JM3 for sd boot. |
| - power on the board. |
| |
| Testing graphics on i.CoreM6: |
| ============================ |
| |
| Build with support for Etnaviv, Qt5 and demo applications: |
| |
| make engicam_imx6qdl_icore_qt5_defconfig |
| make |
| |
| Running kmscube |
| # kmscube -D /dev/dri/card1 |
| |
| Running glmark2-es2-drm |
| # glmark2-es2-drm |
| |
| Running Qt5 Cinematic Demo: |
| - for i.CoreM6 Starter Kit |
| # export QT_QPA_EGLFS_KMS_CONFIG=/root/imx6qdl-icore.json |
| - for i.CoreM6 ofcap10 |
| # export QT_QPA_EGLFS_KMS_CONFIG=/root/imx6qdl-icore-ofcap10.json |
| - for i.CoreM6 ofcap12 |
| # export QT_QPA_EGLFS_KMS_CONFIG=/root/imx6qdl-icore-ofcap12.json |
| |
| # CinematicExperience-demo |
| |
| Enjoy! |
