* 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

|
|
|
This default configuration will allow you to start experimenting with the
|
|
Buildroot environment for the Bananapi M2 Zero. With the current configuration
|
|
it will bring-up the board, and allow access through the serial console.

This configuration uses U-Boot mainline and kernel mainline.

How to build
|
|
============
|
|
|
|
$ make bananapi_m2_zero_defconfig
|
|
$ make
|
|
|
|
Note: you will need access to the internet to download the required
|
|
sources.

|
How to write the SD card
|
|
========================
|
|
|
|
Once the build process is finished you will have an image called "sdcard.img"
|
|
in the output/images/ directory.
|
|
|
|
Copy the bootable "sdcard.img" onto an SD card with "dd":
|
|
|
|
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
|
|
$ sync
|
|
|
|
Insert the micro SDcard in your Bananapi M2 Zero and power it up. The console
|
|
is on the Debug UART on the CON3 header, with serial settings 115200 8N1.
