* 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
Arcturus uCLS1012A SoM
======================
This tutorial describes how to use the predefined Buildroot
configuration for the Arcturus uCLS101A SoM platform.
Additional information about the uCLS1012A System on Module can be found at
https://www.arcturusnetworks.com/products/ucls1012a
and product support for registered users at
https://www.arcturusnetworks.com/support
Building
--------
Return to the top directory <buildrootdir> and execute the following commands.
make arcturus_ucls1012a_defconfig
make
Result of the build
-------------------
After building, you should obtain this tree:
output/images/
+-- arc-ucls1012a.dtb
+-- Image
+-- part0-000000.itb
+-- rootfs.cpio
+-- rootfs.cpio.gz
+-- rootfs.tar
+-- u-boot.bin
+-- ucls1012a.its
Flashing
--------
You'll need to program the image created by buildroot into the SPI NOR flash.
1. Reboot your module and via the serial console press <escape> to enter the B$
u-boot shell.
From the shell you will need to update four environment variables replacing the
IPv4 IP Address with ones that will work with your network and tftp server.
B$ setenv ipaddr 192.168.1.81
B$ setenv serverip 192.168.1.80
B$ setenv gatewayip 192.168.1.1
B$ setenv netmask 255.255.255.0
B$ saveenv
2. Enable tftp server to serve the <buildrootdir>/output/images/ folder.
3. Program the new U-Boot binary (optional)
If you don't feel confident upgrading your bootloader then don't do it,
it's unnecessary most of the time.
B$ tftp u-boot.bin
B$ run program_uboot
4. Program the ITB image (includes Kernel, DTB and Ramdisk)
B$ tftp part0-000000.itb
B$ run iprogram
5. Booting your new system
Reboot your system by reset command
B$ reset
or
B$ run bootcmd
Good Luck !
