5 This file documents the Buildroot support for Engicam i.CoreM6
8 i.CoreM6 Quad/Dual/DualLite/Solo SOM Starter kits:
9 https://www.engicam.com/vis-prod/101120
10 i.CoreM6 Quad/Dual/DualLite/Solo Open Frame 10.1 C.TOUCH kits:
11 https://www.engicam.com/vis-prod/101133
13 This configuration uses U-Boot mainline and kernel mainline.
18 First, configure Buildroot for the Engicam i.CoreM6:
20 make engicam_imx6qdl_icore_defconfig
26 You will find the following files in output/images/:
27 - imx6q-icore.dtb (for i.CoreM6 Quad/Dual)
28 - imx6dl-icore.dtb (for i.CoreM6 DualLite/Solo)
29 - imx6q-icore-ofcap10.dtb (for i.CoreM6 Quad/Dual ofcap 10)
30 - imx6q-icore-ofcap12.dtb (for i.CoreM6 Quad/Dual ofcap 12)
38 Create a bootable SD card
39 =========================
41 To determine the device associated to the SD card have a look in the
42 /proc/partitions file:
46 Buildroot prepares a bootable "sdcard.img" image in the output/images/
47 directory, ready to be dumped on a SD card. Launch the following
50 dd if=output/images/sdcard.img of=/dev/<your-sd-device>
53 *** WARNING! This will destroy all the card content. Use with care! ***
55 For details about the medium image layout, see the definition in
56 board/engicam/icorem6/genimage.cfg
58 Boot the i.CoreM6 boards with SD boot:
59 =====================================
61 To boot your newly created system:
62 - insert the SD card in the SD slot of the board;
63 - connect 3-wire RS232 serial port J28 on board, and connect with other
64 serial end or USB cable(if serial-to-usb converter used) using
65 a terminal emulator at 115200 bps, 8n1;
66 - close JM3 for sd boot.
69 Testing graphics on i.CoreM6:
70 ============================
72 Build with support for Etnaviv, Qt5 and demo applications:
