* 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

QMTECH Zynq XC7Z010 Starter Kit
*******************************
This file documents the Buildroot support for the QMTECH [1] Zynq
XC7Z010 Starter Kit [2]. It is a low cost (~55$) Zynq based
development board. The board user manual is available at
[3]. Additional files are available on Github [4].
Build
=====
First, configure Buildroot for the QMTECH Zynq board:
make zynq_qmtech_defconfig
Build all components:
make
You will find in output/images/ the following files:
- boot.bin
- boot.vfat
- devicetree.dtb
- rootfs.cpio
- rootfs.cpio.gz
- rootfs.cpio.uboot
- rootfs.tar
- sdcard.img
- u-boot.bin
- u-boot.img
- uImage
- zynq-qmtech.dtb
Create a bootable micro SD card
===============================
To determine the device associated to the micro 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 micro 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! ***
Boot the QMTECH Zynq board
==========================
To boot your newly created system:
- put a mini USB cable into the J4 Debug USB Port and connect using a
terminal emulator at 115200 bps, 8n1,
- put the prepared micro SD card in the J2 micro SD card slot,
- plug the 5V power supply on the JP4 barrel jack.
Enjoy!
