* Update buildroot-patches for 2020.11-rc1 buildroot * Update buildroot to 2020.11-rc1 Signed-off-by: Stefan Agner <stefan@agner.ch> * Don't rely on sfdisk --list-free output The --list-free (-F) argument does not allow machine readable mode. And it seems that the output format changes over time (different spacing, using size postfixes instead of raw blocks). Use sfdisk json output and calculate free partition space ourselfs. This works for 2.35 and 2.36 and is more robust since we rely on output which is meant for scripts to parse. * Migrate defconfigs for Buildroot 2020.11-rc1 In particular, rename BR2_TARGET_UBOOT_BOOT_SCRIPT(_SOURCE) to BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT(_SOURCE). * Rebase/remove systemd patches for systemd 246 * Drop apparmor/libapparmor from buildroot-external * hassos-persists: use /run as directory for lockfiles The U-Boot tools use /var/lock by default which is not created any more by systemd by default (it is under tmpfiles legacy.conf, which we no longer install). * Disable systemd-update-done.service The service is not suited for pure read-only systems. In particular the service needs to be able to write a file in /etc and /var. Remove the service. Note: This is a static service and cannot be removed using systemd-preset. * Disable apparmor.service for now The service loads all default profiles. Some might actually cause problems. E.g. the profile for ping seems not to match our setup for /etc/resolv.conf: [85503.634653] audit: type=1400 audit(1605286002.684:236): apparmor="DENIED" operation="open" profile="ping" name="/run/resolv.conf" pid=27585 comm="ping" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

Freescale i.MX6ULL EVK board
|
|
****************************
|
|
|
|
This file documents the Buildroot support for the Freescale i.MX6ULL EVK board.
|
|
|
|
Build
|
|
=====
|
|
|
|
First, configure Buildroot for your i.MX6ULL EVK board:
|
|
|
|
In order to to do so there are two supported options:
|
|
|
|
make freescale_imx6ullevk_defconfig
|
|
|
|
if you plan to use NXP provided U-Boot and kernel.
|
|
|
|
or
|
|
|
|
make imx6ullevk_defconfig
|
|
|
|
if you plan to use mainline U-Boot and mainline kernel.
|
|
|
|
Build all components:
|
|
|
|
make
|
|
|
|
You will find in output/images/ the following files:
|
|
- boot.vfat
|
|
- imx6ull-14x14-evk.dtb
|
|
- rootfs.ext2
|
|
- rootfs.ext4
|
|
- rootfs.tar
|
|
- sdcard.img
|
|
- u-boot.bin
|
|
- u-boot.imx
|
|
- zImage
|
|
|
|
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.
|
|
|
|
Boot the i.MX6ULL EVK board
|
|
===========================
|
|
|
|
To boot your newly created system (refer to the i.MX 6ULL EVK Quick Start Guide [1] for guidance):
|
|
- insert the SD card in the micro SD slot of the board;
|
|
- 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!
