10Build
11=====
12
13First, configure Buildroot for your i.MX6UL EVK board:
14
15In order to to do so there are two supported options:
16
17  make freescale_imx6ulevk_defconfig
18
19if you plan to use NXP provided U-Boot and kernel.
20
21or
22
23  make imx6ulevk_defconfig
24
25if you plan to use mainline U-Boot and mainline kernel.
26
27Build all components:
28
29  make
30
31You will find in ./output/images/ the following files:
32  - imx6ul-14x14-evk.dtb
33  - rootfs.ext4
34  - rootfs.tar
35  - sdcard.img
36  - u-boot.imx
37  - zImage

39Create a bootable microSD card
40==============================
41
42To determine the device associated to the microSD card have a look in the
43/proc/partitions file:
44
45  cat /proc/partitions
46
47Buildroot prepares a bootable "sdcard.img" image in the output/images/
48directory, ready to be dumped on a microSD card. Launch the following
49command as root:
50
51  dd if=./output/images/sdcard.img of=/dev/<your-microsd-device>
52
53*** WARNING! This will destroy all the card content. Use with care! ***
54
55For details about the medium image layout, see the definition in
56board/freescale/common/imx/genimage.cfg.template.

58Boot the i.MX6UL EVK board
59=========================

61To boot your newly created system (refer to the i.MX6UL EVK Quick Start Guide
62[1] for guidance):
63- insert the microSD card in the microSD slot of the board;
64- verify that your i.MX6UL EVK board jumpers and switches are set as mentioned
65  in the i.MX6UL EVK Quick Start Guide [1];
66- put a micro USB cable into the Debug USB Port and connect using a terminal
67  emulator at 115200 bps, 8n1;
68- power on the board.
