* 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

Intro
|
|
=====
|
|
|
|
This default configuration will allow you to start experimenting with
|
|
the buildroot environment for the MacchiatoBin board based on the
|
|
Marvell Armada 8040 SoC. Documentation for the board hardware and
|
|
software is available on the wiki at: http://wiki.macchiatobin.net
|
|
|
|
This default configuration will bring up the board and allow access
|
|
through the serial console.
|
|
|
|
How to build
|
|
============
|
|
|
|
Default configuration provides the following BSP versions:
|
|
- Linux v5.6.3 (mainline)
|
|
- U-Boot v2020.01 (mainline)
|
|
- ATF v1.5-18.12.2 (Marvell)
|
|
|
|
To build images run the following commands:
|
|
|
|
$ make solidrun_macchiatobin_defconfig
|
|
$ make
|
|
|
|
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 bs=1M conv=fsync
|
|
$ sudo sync
|
|
|
|
How to boot the board
|
|
=====================
|
|
|
|
The MacchiatoBin board can be setup to load the bootloader from
|
|
different sources including eMMC, SPI flash, and SD-card.
|
|
|
|
On Rev 1.2 board to select boot from SD-card the DIP switches
|
|
SW1 and SW2 should be configured as follows:
|
|
|
|
SW2: 01110
|
|
SW1: 1xxxx
|
|
|
|
The upcoming Rev 1.3 board will have a single pins header J1 instead
|
|
of the SW1/2 DIP switches. To boot from SD-card the setting of J1
|
|
jumpers should match the DIP switches of Rev v1.2 board
|
|
from left to right:
|
|
|
|
J1: 011101xxxx
|
|
|
|
Insert the micro SDcard in the MacchiatoBin board and power it up.
|
|
The serial console is accessible at the micro-USB Type-B connector
|
|
marked CON9. The serial line settings are 115200 8N1.
|
|
|
|
U-Boot environment
|
|
==================
|
|
|
|
By default current configuration provides U-Boot that keeps environment
|
|
in SD/eMMC. However, if needed, u-boot-fragment.config can be tweaked
|
|
so that U-Boot will keep environment in SPI flash. On the first boot
|
|
SPI flash may be empty or it may contain a stale environment that
|
|
prevents proper boot. Then the following commands can be used
|
|
to boot the board:
|
|
|
|
=> ext4load mmc 1:1 0x01700000 /boot/uEnv-example.txt
|
|
=> env import -t 0x01700000 $filesize
|
|
=> boot
|
|
|
|
The example environment from uEnv-example.txt can be written to
|
|
SPI flash using the following commands:
|
|
|
|
=> env default -f -a
|
|
=> ext4load mmc 1:1 0x01700000 /boot/uEnv-example.txt
|
|
=> env import -t 0x01700000 $filesize
|
|
=> saveenv
